Men, Will You Join With Me for 31 Days of Purity?

Men, I want to offer you a challenge. You too, women, but allow me speak to the men first. Beginning on March 1, I am going to begin a program I’m calling 31 Days of Purity. This is for all of us—for those who are young and those who are old, for those who are married and those who are single, for those who struggle mightily in the area of sexual sin and for those who may barely struggle at all. I would love it if you would commit with me to 31 Days of Purity—thirty-one days of considering what God’s Word says about sexual purity and thirty-one days of praying that God would help us fight sin and pursue holiness in this area.

Will you join me?

What If I Don’t Struggle?

A little while ago I wrote an article titled When You’re at Your Best, Plan for Your Worst. My point there was that even if you have gained significant victory in this area, thank the Lord, but don’t stop battling. What I said there still applies:

There is a kind of weakness, a kind of vulnerability, that may come when we are convinced of our strength. It is when we are not being tempted, it is when we are standing strong in the Lord’s grace, that we ought to consider the times we will be weak and tempted and eager to sin. We need to assume such times will come and we need to use the moments of strength to put measures in place that will protect us when we are weak.

Also, even as you pray for yourself, you can partner with a friend who may not be experiencing the same victory. Encourage him along. There is every reason for you to join us, even if you are not struggling in this area.

What About Women?

Women, you can be involved too. I would love it if you would follow along, read what God’s Word says, and then pray for the men in your life: your husbands, your sons, your grandsons. What a blessing it would be to them if you will pray for them in an area in which Satan seems to be winning so many battles. Also, if you are struggling in the area of sexual purity, you’ll easily be able to adapt the devotionals and prayers to your own use.

How Does It Work?

Men, here’s how to get started.

First, pray about people who might join you in this challenge, and then ask them. I am convinced this time will be especially encouraging if you ask a friend or two to join you and if you make it a point to pray with and for one another.

Second, consider joining our 31 Days of Purity Facebook group. It is optional, but you will find it a good place to go for discussion and encouragement. (Note: that Facebook group is for men only; here is one for Women Supporting Men)

Finally, beginning on March 1, I will post a devotional every morning. I will be writing some of them, Mike Leake (with whom I am teaming on this challenge) will be writing some of them, and we have also asked a few friends (whom you may recognize) to help out from time-to-time. Each post will include a short section of the Bible, a couple of paragraphs of explanation or application, and a prayer. You can ponder the Scripture, read the devotional, and pray the prayer. Obviously this is no magic talisman that will ward off sin. However, since we believe in the power and authority of God’s Word and since we believe that God loves to hear and answer our prayers, why shouldn’t we expect that he will move powerfully in our lives?

It all begins right here on March 1. If you would like to begin thinking now about sexual purity, we’ve reduced the price on my book Sexual Detox, so it’s just $1.99 for the Kindle edition (I haven’t seen the price adjusted yet on Amazon, but it will change soon!). You can buy the ebook version direct from Cruciform right here, or the print version (just $5.49) right here.

    Some Unexpected Blessings of Christian Friendship

    While I was sitting at John MacArthur’s memorial service and hearing his friends tell of their love for him (and his for them), I began to ponder some of the unexpected blessings that have come with both having friends and being a friend. Here are just three that came to mind…
