Some time ago, no doubt while I was awake in the middle of the night with one of the children, I saw a documentary about some weird disease that causes a patient’s skin to harden. This disease often sets in during childhood and causes the skin to become hard and shiny. I searched around to find the name of this condition and I think it must be “systemic sclerosis.” “Dermatology Online Journal” describes it this way: “Systemic sclerosis is a clinically heterogeneous, systemic disorder which affects the connective tissue of the skin, internal organs and the walls of blood vessels. It is characterized by alterations of the microvasculature, disturbances of the immune system and by massive deposition of collagen and other matrix substances in the connective tissue.” That doesn’t mean anything to me, but I guess it all adds up to “hard and shiny.” Though most people experience the disease only moderately (these people see hardening of the skin mostly on their hands and forearms) there are some who see the disease progress so that the skin hardens all over their bodies, leaving even their faces set in hard “masks.” Sometimes it will progress to the organs, hardening them and leading to an early death. It is a horrifying illness when it progresses past the point where it can be easily and successfully treated.
I thought of this while reading Gum, Geckos and God by James Spiegel. In this book (to borrow a line or two from Publishers Weekly) “Spiegel, philosophy professor at Indiana’s Taylor University, takes deep issues of the Christian faith and dumps them smack into real life with a little help from his children… Spiegel ponders the great issues of the faith with a light touch, thanks to the innate comedy of kids, but also to his own brand of humor.” In a chapter entitled “How Can God Fix Us” he looks at how God can overcome our sin–how He can fix what we have done to ourselves through our sinful natures. He uses The Lion, the Witch, and the Wardrobe to springboard into this conversation, explaining how his son, at only four years of age, was able to draw the connection between the death of Aslan and the death of Jesus Christ. He mentions that, when teaching a faith and culture course at Taylor University, he often asks students to raise their hands if they became Christians at the age of four or younger. Almost invariably at least a few of the hands go up. This is amazing, he says, “considering that comprehension of the gospel demands that one understand such weighty moral concepts as duty, sin, punishment, love, and forgiveness.”
“I am sure,” he says, “there are many parents who are mistaken in thinking that their kids comprehend the gospel. But the point is that many do. And given their stage of cognitive development, this suggests something supernatural is going on.” And truly something supernatural must be going on for children to understand what too often escapes many adults. A child can sometimes grasp deep spiritual truths that are lost on adults who are, in any other wise, far more wise and far more intelligent. Those who hate the Christian faith and who hate religion in general will insist that children believe because they have been indoctrinated. But we know better; we know that God can work his supernatural work of regeneration even in a child.
Here is why it is more difficult for adults than for children to come to know the Lord. “Sin causes cognitive malfunction, and this is especially so when it comes to moral-spiritual matters. The older we grow without being redeemed, the more polluted we are by our sin and the more entrenched we become in our corrupt patterns of thinking. Though by no means pure, children are less corrupted in their thinking and less hardened in faulty thinking patterns simply by virtue of their being younger. So it shouldn’t surprise us that the overwhelming majority of Christians come to faith by the time they are eighteen years old.”
Of course there is a second barrier to coming to Christ and it is a spiritual one. As Paul explains in 1 Corinthians 2:14, without the Spirit’s prior work, no one can grasp the gospel. The spiritual nature of the gospel, that part of the gospel message that transcends natural cognitive abilities, must be overcome by the Holy Spirit. “So there are two major barriers when it comes to grasping and accepting the gospel,” says Spiegel. “One is the spiritual nature of the gospel, which transcends natural reason. The other is our sin, which corrupts cognitive function. The Holy Spirit must graciously overcome both of these obstacles in order to work redemption in any human heart. This implies that all Christian conversions are doubly miraculous and doubly gracious. And given that even after conversion Christians continue to struggle with sin, the Spirit must constantly work to keep us faithful. Job really nailed it when he said that God, ‘performs wonders that cannot be fathomed, miracles that cannot be counted’ (Job 5:9).”
And this takes us back to systemic sclerosis. A person’s spiritual condition, it seems, is much like the condition of a patient with systemic sclerosis. While all humans are born sinful, children have less of the pollution and less of the hardening of adults. While the extent of our depravity cannot change, for from the moment of conception it encompasses all that we are, the degree will and must change. Life without God progresses much like the disease. It causes increased hardening. What was once soft becomes hard; what was once supple becomes stiff and stretched. The longer a person denies God and the more his internal pollution increases, the more hardened he becomes against God and against His gracious offer of salvation. No wonder the Bible is filled with commands and exhortations that as parents we dedicate ourselves to teaching our children what God requires of them. And what impetus this should give us to obey Him! “You shall therefore lay up these words of mine in your heart and in your soul, and you shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. You shall teach them to your children, talking of them when you are sitting in your house, and when you are walking by the way, and when you lie down, and when you rise…”
