Like countless others, while I enjoyed the film O Brother, Where Art Thou, I was captivated by the music. I was one of the millions who immediately purchased the soundtrack and enjoyed discovering, or rediscovering, that old-school country and bluegrass music. It was there that I first heard of The Peasall Sisters. These three girls, unknown at the time, tried out to be the singing voices of three little girls in the film. Against all odds they were selected for the part. This began a lightning-quick rise to popularity and they embarked, along with others who contributed to the soundtrack, on a nation-wide tour.

The DVD is balanced between showing the girls singing and showing their daily lives. The songs on the album are performed live and raw at Pucketts in Franklin, Tennessee. They sing many traditional songs along with some of their most popular tunes: “Home To You,” “The Old Churchyard,” “Hallelujah, I’m Ready,” “The Old Account,” and “Be Thou My Vision.” Compared to the album Home To You (you can listen to several MP3s here) the songs sound somewhat rough, yet for a live performance the girls show remarkable skill in their harmonies and the playing of their instruments. When it comes to musical talent, these girls are incredible, especially when you consider their ages: 18, 14 and 12.

It is interesting being given a glance into the life of this family. They are a homeschooling family, and one that was dedicated to homeschooling long before they headed out onto the road to perform. They are a big family with six children so far and a committment to letting God determine how many children they will have. They are a close family, one that lives together, studies together and travels together. When the girls embark on a tour, the whole family piles into the R.V. and they travel together. Dad, a former music minister at a large Baptist church, is the fourth member of their band, playing bass and holding back the boys.

Together the family makes a compelling picture of the power of the gospel. Throughout their rise to popularity this family has stayed grounded in their faith and family. When asked what they hope people to take away from one of their concerts the answer is uniform, from dad to the youngest daughter: they want people to hear and know the gospel. They want people to see the gospel in action. They are unashamed to declare their allegiance. Here are a few quotes from the family when asked about their vision for what they do. “When people leave our concerts I want them to know that we really enjoy what we do. That they’ve seen the gospel and they’ve seen a Christian family and they’ve seen good musicians and they’ve heard some good music. But they’ve seen a family who enjoys what they do.” “I just want to have a godly personality and a godly influence on people.” “I want them to have experienced the presence of God. That is my one, true desire. Second of all I want them to take home a new appreciation of bluegrass and traditional country.” “I want musical excellence to be a part of the picture, but more than that I guess the number on priority, or something I want my family to be known for, is honoring God in our daily lives. Shining light in the darkness for God.”

This is one of my new favorite DVDs and one I expect I will watch (and listen to) regularly - probably whenever I need that bluegrass fix. I recommend this one on two levels, both for the music, which is outstanding, and the story of this family, which is inspiring. You can purchase the DVD from Franklin Springs Family Media. Included on the DVD are several compelling extras, including unreleased tracks, a music-only version of the DVD and so on. You may also enjoy the Home To You CD which is available from Amazon.

In the spring of 2003, three young Americans set out for Africa, in search of adventure and a story. They found what they were looking for. They found a tragedy that changed their lives and has since changed the lives of many who have heard the story. They found the invisible children of Uganda.

Jason Russell, Laren Poole and Bobby Bailey headed to Africa with a desire to have their lives changed. Armed with camera equipment they had purchased on eBay, they set out for Sudan, a country that has been rocked with continual war and strife. Unable to find anything in Sudan that could capture their short attention spans they set out for Uganda and soon found themselves in the northern part of that nation. It was there that they found their story.

What they found were children who were being abducted and forced to participate in one of the meaningless, brutal wars that rage in Africa. Young children, even just six or eight years old, are taken from villages and the countryside, are indoctrinated, and forced to bear arms against their own people. They are subjected to unbelievable horrors. They watch their friends and siblings being killed and dismembered simply so their captors can destroy their innocence and shock them into subjection. They are warned that any attempts at escape will end in a brutal, violent death. Those who do escape are hunted like dogs.

Every night the large towns in this part of Uganda fill with children - children who flee the surrounding villages lest they be abducted. Thousands of children migrate to bus parks and hospitals to spend the night in relative safety. Largely unsupervised and with little more than a blanket and the clothes on their backs, these children return night after night. They have no choice. They are desperately poor and suffer terrible abuses. It truly is a tragedy the likes of which is foreign to the mindsets of North Americans.

Invisible Children is a fast-paced MTV-style documentary designed to appeal primarily to young people. The filmmakers say, “This wonderfully crappy rock-and-roll documentary is something truly unique. To see Africa through young eyes is funny, and heart breaking, quick, and informative - all in the very same breath.” While it is not the quality of some of the better documentaries I have seen, I found it well-made and well-produced. In fact, the only real problem I had with the quality of the film was the narrating and voice-overs. They were stilted, unnatural and unsuited to the format of the film. What I watched was only a rough cut of the DVD and I do hope they address the narration before releasing a final cut.

Having brought the story of these invisible children before a North American audience, Russell, Poole and Bailey have great plans for aiding the children. Their plan has three parts. First, they wish to expose the effects of a 20 year-long war on the children of Northern Uganda by telling their stories in a relevant way. Second, they wish to empower the individual viewer towards action (volunteering, donations, the bracelet campaign, political pressure, etc.). Finally, they would like to use the proceeds to provide aid to the invisible children on the ground, in Uganda. “Our dream,” they say, “is to inspire the young and young at heart, to challenge their thinking, and empower them to ‘be the change they wish to see in the world’ through action.” To this end the organization encourages individuals to host viewing parties, to be creative, and ultimately to donate money to the cause. According to the extra features on the DVD, the young men have partnered with World Vision to design communities in Uganda that will provide safe housing and education for the children. These projects can begin only when there are sufficient funds available.

The story this DVD tells is powerful and convicting. It is heart-breaking. I admire the young men for finding this story and for their passion in telling it. Unfortunately I would be hesitant to donate funds to their campaign. I have every confidence that these people are sincere in their desire to help the children of Uganda, but I am less convicted that they will be able to make the impact they desire. Sincerity is not enough: they must also have credibility. I felt that the apparent obsession with South Park, Dave Chappelle and Family Guy along with the immature activities recorded at the beginning of the film (blowing up termite hills with gasoline, chopping snakes into pieces with an axe, and close-in shots of vomitting) damage the credibility of the young men and thus their organization. This may appeal to their target audience, but it will surely prove a hindrance to those who are older and are likely to have more resources available to them.

I should note that the organization does have an active board of directors and that my fears may be unreasonable. “Invisible Children has an active board of directors made up of local businessmen and women who are passionately committed to growing and expanding the effect of Invisible Children both domestically and abroad. They meet on a bi-monthly basis and have the ultimate legal control over Invisible Children. The filmmakers of Invisible Children have creative authority over the film. Their vision is the driving force behind the movement of Invisible Children. The staff at the IC office takes the vision and facilitates action. They are in charge of setting up screenings and events, organizing volunteers, budgeting/financial record keeping, communication with IC representatives in Africa and coordinating the international campaigns.”

My other concern was that, while the three filmmakers are professed Christians, Invisible Children is not a Christian organization. I do hope that those who help the children will do more (and certainly not less) than provide the necessities of life, but also share the Gospel which brings eternal life.

Invisible Children was a chilling DVD and made me profoundly grateful to live in such a safe and innocent part of the world. It truly is a blessing to live in a land of freedom and safety. It made me aware of horrors that are almost unimaginable. I have little doubt that it will stir and motivate many young people to look beyond their comfort zones and see the importance of extending help and comfort to those who are in need. I hope it does. Ultimately I hope God uses it to bring the Gospel to those hurting, abandoned, invisible children, for they are not invisible to Him.

I guess that if a movie about Jesus became one of the highest grossing movies of all time (no pun intended), we should not be surprised to see other unusual subject matter become popular at the box office. This is the case with March of the Penguins, a documentary about the life cycle of the Emperor Penguin. This strange species lives in the Antarctic in what is surely the most horrific climate in the world.

When the Antarctic summer begins to draw to a close the Emperor Penguin, having spent the summer feeding in the ocean, feels the need to march inland to the very place where it was born. So begins a comical trek of penguins, single-file, marching day after day for up to seventy or even eighty miles. Having arrived at the place of their birth, the penguins begin to seek out a mate, somehow carefully choosing one that seems ideal to them. They begin a loving, tender dance and song which leads to breeding. Weeks later the female delivers a single egg which she immediately and carefully passes to her mate. She, approaching death because of losing much of her body weight to the egg, returns to the sea and feeds. The male, having placed the egg on his feet, incubates it for two months, standing still and huddling together with the rest of the pack to keep warm. Through terrible winter storms and temperates approaching 100 degrees below zero, they stand together to protect their young. When finally the egg hatches, the female returns and finds her mate. She then takes the baby and the male, not having eaten for several months, heads to the ocean to eat. In the following months the male and female takes turns feeding and caring for the young.

It is this amazing cycle that is captured in March of the Penguins. The narrator, Morgan Freeman, tells us that this film is a love story. But it is more than that. In his review, in which he gave the film 4.5 stars out of 5, Roger Ebert wrote the following:

I think it is more accurately described as the story of an evolutionary success. The penguins instinctively know, because they have been hard-wired by evolutionary trial and error, that it is necessary to march so far inland because in spring, the ice shelf will start to melt toward them, and they need to stand where the ice will remain thick enough to support them.

Why do penguins behave in this manner? Because it works for them, and their environment gives them little alternative. They are Darwinism embodied. But their life history is so strange that until the last century, it was not even guessed at. The first Antarctic explorers found penguins aplenty, but had little idea where they came from, where they went to, and indeed whether they were birds or mammals.

While I generally agree with his assessment of the film, Ebert misses the mark in this area. The Emperor Penguin does not embody Darwinism but clearly shows the handiwork of a Creator. “For since the creation of the world God's invisible qualities--his eternal power and divine nature--have been clearly seen, being understood from what has been made, so that men are without excuse” (Romans 1:20). It is startling to think that everyone who watches this incredible film has further left himself without excuse when he stands before God and attempts to plead ignorance.

The Emperor Penguin, being far more than a mere “evolutionary success,” is, in fact, one of the creatures that evolution cannot fully explain. Answers in Genesis, drawing from the excellent DVD series Incredible Creatures That Defy Evolution explains:

[C]onsider how (in a climate which no other living creature can endure), the emperor penguins get to the same destination, but via a different path, each time. As the narrator poses the question, "How do they get there--by an invisible compass inside?" And these aren't the only birds that seem to have a built-in compass--migratory birds do as well.

Dr. Jobe Martin points out in the DVD Incredible Creatures that Defy Evolution (Volume 3) how amazing it is that the egg, which is only a couple of inches from the ice, doesn't freeze. "The fact that their feet don't freeze on the ice is a miracle in itself," he adds.

With mother gone, the male penguin must carry and protect the egg for more than 60 days (practically without moving), without eating, and while exposed to the worst weather conditions on earth. (When all is said and done, the male will go without food for 125 days.)

So, how do the male penguins keep their eggs, let alone themselves, from freezing in the extreme polar weather? As a way to resist the blizzard, the penguins regroup in a turtle-like formation while swirling around like a snail. Compressed against each other, they take turns being in the middle where it's the warmest and being on the outside where it's the coldest. All the while, they are shuffling along the ice, careful not to lose the egg that is so delicately balancing on their feet.

What makes these male penguins cooperate in such perfect harmony? According to an article by the Australian Antarctic Division (AAD),3 it's their instinct as a social creature.

Another special adaptation of the emperor penguin, according to the AAD article, is the penguin's ability to "recycle" its own body heat. The emperor's arteries and veins lie close together so that blood is pre-cooled on the way to the bird's feet, wings and bill and warmed on the way back to the heart.

Many evolutionists say that the penguin is a bird that supposedly lost its ability to fly, as Dr. Martin points out in Incredible Creatures that Defy Evolution (Volume 3). "But evolutionists haven't come up with any ancestors for the penguin," he counters. "So what kind of bird was it that became a penguin and lost its ability to fly?" he adds.

The Emperor Penguin is irrefutible evidence of a Creator. This documentary (inadvertently, I’m sure) does a wonderful job of presenting this creature in a way that showcases God’s creative ability and his love and care for every creature. This is a film for the whole family and one that will stir your heart with awe towards the One who created this world and everything in it.

Last night, at long last and having had it recommended to me many times, I sat down to watch the film To End All Wars. For those who do not know of it, it is the story of Ernest Gordon who was a captain of the Scottish Argyles during the Second World War. After escaping the Japanese at the fall of Singapore, Gordon and some fellow soldiers sailed a junk almost 2000 miles, only to be captured by Japanese. They were taken prisoner and were sent to work on the Burma-Siam Railroad (which you may know from the film Bridge of the River Kwai).

Before I continue allow me to provide a bit of a warning. I was quite surprised at the volume of swearing in this film. Usually I would not be surprised to find bad language in a war movie, but was surprised at this one primarily because the people who recommended it to me made no mention of it. Thankfully, because of the subject matter, it was not a film we decided to watch with the children present.

I will leave summaries of the content of the film to others and just mention a few brief points about my experience.

In some ways I enjoyed this movie and in others I didn’t. I enjoyed the subject matter and the deep spiritual message behind the film. The film was produced by a professed Christian and this was obvious in the overall theme of struggle with sin, redemption and forgiveness. I don’t know that anyone could watch this movie and not come away without a deep sense of the power of forgiveness and the need for redemption. Key characters grapple with their depravity not through their own actions but through the realization that they are, in reality, no better than the very people they hate. So there is a real maturity to the message - far more than we might find in other “spiritual” movies.

I was disappointed for two reasons. First, while I am not intimately familiar with the story that inspired the film, and have not read Gordon’s book by the same title, I know enough to realize that the producers deviated in several key ways. Certain characters were combined to form one and actions that ought to have been attributed to one person were attributed to another. There was also a key scene of suffering that I believe was changed substantially so as to make a more clear parallel to Christ’s sacrifice. Secondly, I found that many of the characters were shallow and underwent little development. In fact, many of the characters seemed little more than caricatures and were typecast into specific roles from which they could not deviate. Every character had his part, and while each played it well, it allowed little room for development or surprise. From all I have read the real story behind To End All Wars is inspiring and displays the best of what God can do in the lives of men and I don’t understand why the story was rewritten.

Despite those small complaints the movie was well-made and, as I have said, contain a strong, biblical message. It would be a mistake, however, to say that this is a “Christian film,” whatever that might mean. Like most films, it tells a story, and like only a few, it tells it well. But as with most in the genre of “inspired by a true story” films, I was left more interested in reading the book than watching the film. As for the swearing, I don’t know how to reconcile that with my Christian worldview. Judging by the caliber of Christian by whom this movie was recommended to me, it is not an issue even conservative, Reformed Christians feel strongly about. Yet I have difficulty recommending it on the basis of the language. I am looking forward to reading the book.

The Torchlighters video series is a new series of animated DVD’s dedicated to “Highlighting the honor, integrity and life-changing experiences of those well-known and little-known Christian men, women and children who in response to God’s call, dedicated their lives to a life of whole-hearted commitment and passionate service to Jesus.” It is a production of Christian History Institute along with International Films and Voice of the Martyrs. The first in this series is The Jim Elliot Story. Elliot is widely known in the Christian world because of the prolific writing and speaking career of his wife, Elisabeth. In 1956 Jim Elliot, along with four other young missionaries, were killed by a vicious tribe of Euadorian natives whom the men were trying to reach with the gospel. The tragedy has become an inspiration to people across the world as they have seen the families of those who were killed continue to love and serve among the tribe who put them to death.

This video, which is about a half hour long, provides a brief glimpse of Elliot’s short career as a missionary. It introduces each of the men who served with him and shows their love for the Lord and their determination to serve him whatever the cost. The cover for the DVD says, “In the inaugural Torchlighters episode we follow Jim’s adventures from his college years to his work in the jungles, showing young people his faith in action as he answers God’s call to do the seemingly impossible.” The story is presented well, focusing on the unshakeable faith of these young men.

It should be noted that the series is targetted primarily at children between the ages of eight and twelve. I was hoping that I could show this film to my son, who is five, but my wife feels that it might be a little too intense for him. Perhaps next year. There is nothing too terribly graphic (certainly by today’s standards) but the viewer will nevertheless witness the deaths of many people, including the hero of the story.

Included with the film is a study guide suitable for children that includes a leader’s guide and reproducible student worksheets; an interview with Steve Saint, son of Nate Saint who was killed along with Jim Elliot and who has gone on to serve with the same tribe; and a video autobiography of Marj Saint Van Der Puy, Nate’s wife. These add significant value to what is already a strong presentation, though these extras will appeal far more to adults than to children.

Future titles in the Torchlighters series include The William Tyndale Story (release is imminent), The John Bunyan Story (set for a 2006 release) and The Eric Liddell Story (also set for a 2006 release). This looks like a wonderful little series and I am sure each of the titles will be a valuable addition to any church or personal library. I hope to make each of these titles available to my children.

The Jim Elliot Story is well-made and will surely appeal to the target audience. It will share with children the deep and inspiring faith of some of God’s most dedicated servants. I am glad to recommend it.

The Jim Elliot Story is available from Vision Video (800-523-0226). Adults may be interested in Beyond the Gates of Splendor.

Until the 1960’s, the Yali tribe of Papua (formerly known as Irian Jaya) existed much as they had for thousands of years. An adventure web site says the following of the tribe. “Yali tools have not changed in a thousand of years [sic] - stone axe of pointed shards wrapped tightly onto a wooden stick, net carrying bags supported from the forehead, thick bows five or six feet long, and arrowhead carved to a purpose -broad and flat for large game, a triple barb for birds, notched and tapered black for setting tribal disputes.” They truly were a Stone-Age people who had existed in isolation from the industrialized world. They had very little knowledge of anything beyond their own villages. They were warriors, cannibals and lived in constant fear of evil spirits. Revenge was an admirable trait in their culture which, not surprisingly, knew little peace.

But in the 1960’s a group of missionaries entered their world and brought with them the gospel of Jesus Christ. Once language barriers had been crossed, the Good News was received with enthusiasm and a type of revival swept the tribe. Men who had once been medicine men became teachers of the Word of God. People who had once lived in fear of evil spirits now placed their trust in the Creator. The people, men and women alike, were educated and taught to read and write.

This DVD presentation, which is roughly a half hour in length (and is available in several languages) features three of the missionaries who were involved in evangelizing the tribe, Bruno de Leeuw and both of John and Gloria Wilson. The video documents the amazing transformation of this people as God changed their lives through the Scriptures. It tells of the long but rewarding process of translating the Scriptures into the native language.

The most amazing moment captured in this presentation, and one of the most powerful things I have witnessed, was the joy of the people as they received the first translations of the Bible into their own language. The New Testament was completed in the ’90s and the entire Bible in the year 2000. To watch the Yali people jump and dance and sing and celebrate over something we take so for granted was both powerful and moving. It quite literally moved me to tears. How I wish we, in the Western world, could experience that excitement and joy.

There is some bonus material included on the DVD. This includes “Lessons from the Yali Story” (a discussion of missions, a music video, two shortened versions of the main documentary, some commentary and John Wilson’s story of surviving cancer.

The Yali Story is a fascinating story and one that has served to encourage many Christians. I highly recommend this DVD for church, public or private libraries.

The Yali Story is available from Vision Video (800-523-0226). It can also be purchased through Amazon.com

There are a few events or occasions in every generation where time seems to stop. Those old enough to remember J.F.K’s assassination tend to not only remember the news reports, but remember where they were and who they were with when they heard about his death. Many people still remember how they felt when they heard that the space shuttle Challenger was destroyed just seconds after lift-off, or more recently, when they began to hear news reports about planes plowing into the World Trade Center in New York City. Another tragedy that stopped a nation, and really an entire continent, was the shootings in Columbine High School on April 20, 1999.

As with all tragedies, there arose out of Columbine stories of untold grief along with stories of great hope and rejoicing. Untold Stories on Columbine places the spotlight on just one of the young people who lost her life that day. Rachel Joy Scott was only seventeen years old but had placed her faith in God and sought to be a light in the darkness of the halls at her high school. From all accounts she was a fun, happy and vivacious young woman who was bold in sharing her faith. The DVD is a video recording of a speech her father, Darrell Scott, gave at a Baptist church in Tennessee. It also contains footage from Rachel’s funeral which was broadcast worldwide on CNN.

Apparently only a couple of weeks before the shootings Rachel, true to her convictions, had witnessed to the two gunmen. Her father recounts what has become a popular but unsubstantiated account of the events surrounding her death. Rachel had already been shot twice while standing outside the school building. One of the gunmen, seeing that she was wounded, grabbed her hair and pulled her head towards him, asking “Do you still believe in God?” When she replied, “You know I do,” he immediately shot her through the temple. This same affirmation of faith was attributed to Cassie Bernall (and was later disproven, despite books and songs in her honor) and to Valeen Schnurr who survived. It is entirely possible that the gunmen asked this question of multiple people. We will never know with any certainty whether Rachel’s final words were a statement of her faith, but what we do know is that she was a remarkable young woman who left a legacy that has since inspired thousands or even tens of thousands of young people.

The untold stories of Columbine are not the stories of Rachel or Cassie, but of those who were stirred to follow their example in finding meaning and refuge in Christ. While many stories that arose in the aftermath of that day have long since been proven false, what no one can disprove or take away is the faith of those young women and many of the other students. We cannot know how many lives were touched and how many hearts stirred to hear of young believers who lost their lives - maybe as martyrs and maybe not - leaving behind a legacy of faith.

Darrell Scott is a natural speaker and his presentation is powerful and stirring. He shares stories from his daughter’s past and relates many of her premonitions that her life was not going to last long. Equally powerful are the testimonies of Rachel’s friends and family as they pour out their hearts at her funeral. The grief, still so new and fresh, is palpable. I had two concerns with the presentation. First, it seemed that he must have already given the speech hundreds of times, for it seemed to be done with little spark or emotion. Secondly, discerning viewers may find themselves squirming at times, as Scott is a Pentecostal and holds back nothing, even in front of his Baptist audience. Knowing his audience he attempts to explain his beliefs on visions, dreams and direct revelation from God, but in the end I agree with a friend he mentions in his speech who always encourages him to “show me in the Word!”

This is an interesting DVD and well worth the 80-minute investment. Whether or not Rachel Scott died with a confession of her faith upon her lips, we know from her life and from the legacy she left behind that she believed deeply in the Lord and was called home from that bloodstained field to her Savior’s side. Her life and death were both a powerful testimony to the grace of God.

One of my most vivid memories of the year my family spent in Scotland happened soon after we moved there. We were progressively touring the town of Edinburgh and had already visited The Royal Mile, Edinburgh Castle, the home of John Knox and many of the other prominent locations. Eventually we made our way to Greyfriars, the church where many of the Scottish Covenanters were buried after being killed (and often first being mericlessly tortured) for their faith. We were astonished and not a little upset to find that the main attraction of the cemetary at Greyfriars is not the graves of those who were martyred, but a monument to a little terrier who sat faithfully at his master’s grave for many years after his death.

In retrospect it seems almost fitting for the Covenanters, who have largely been overlooked in history, to be overlooked where their bodies now lay.

The Covenanters were a group of Presbyterians from 17th-century Scotland, considered radical today, who covenanted with God for the good of the people of their nation. They were persecuted by the English and hunted down all across the nation. A great many of them paid with their lives. Wikipedia says the following of the Covenanters: “Gathering around them many of the Covenanters who clung tenaciously to their standards of faith, these ministers began to preach in the fields, and a period of persecution marked by savage hatred and great brutality began. Further oppressive measures were directed against the Covenanters, who took up arms about 1665, and the struggle soon assumed the proportions of a rebellion. The forces of the crown under John Graham of Claverhouse and others were sent against them, and although the insurgents gained isolated successes, in general they were worsted and were treated with great barbarity. This period of repression was remembered in folk memory as “the Killing Time”. They maintained, however, their cherished covenants with a zeal which persecution only intensified; in 1680 the more tenacious members of the party signed a document known as the “Sanquhar Declaration,” and were afterwards called Cameronians from the name of their leader, Richard Cameron. They renounced their allegiance to King James and were greatly disappointed when their standards found no place in the religious settlement of 1689, continuing to hold the belief that the Solemn League and Covenant should be made obligatory upon the entire nation. The Covenanters have a martyrology of their own, and the halo of romance has been cast around their exploits and their sufferings. Their story, however, especially during the time of their political predominance, is part of the general History of Scotland.”

The Scottish Covenanters is an hour-long DVD that examines these people and the conflict they faced. It introduces many of the most important Covenanters and the men who persecuted them. It describes the faith and the covenants for which so many were willing to die and examines the impact of this movement in Scottish history. It is quite a good little presentation - well made and filled with historical facts and visits to the important historic locations. It is certainly educational and well worth watching. I recommend it.

The Scottish Covenanters is available from Vision Video or from Amazon.
