At the Passion 07 conference in Atlanta last week, John Piper preached a remarkable message with a remarkable title: How to Deal With the Guilt of Sexual Failure for the Glory of Christ and His Global Cause. The title brings together several themes that at first glance seem unrelated -- guilt, sexual sin, the glory of Christ and the global cause of world missions. If someone wants to know how preaching in the 21^st century can be both biblical and yet realistic and ultimately hope-giving, then read this sermon.

Piper starts with the assumption that many young people struggle with the guilt of sexual sin (a fact we all recognize), but he goes further and says that that guilt often leads them to give up on serving the Lord and to settle for a life of middle class materialism. The tragedy here is that Satan then wins a double victory -- once when the original sin occurred, and later (and sometimes for a lifetime) when that residual guilt keeps them from doing anything for the Kingdom. Here is a taste of what Piper said:

The great tragedy is not mainly masturbation or fornication or acting like a peeping Tom (or curious Cathy) on the Internet. The tragedy is that Satan uses the guilt of these failures to strip you of every radical dream you ever had, or might have, and in its place give you a happy, safe, secure, American life of superficial pleasures until you die in your lakeside rocking chair, wrinkled and useless, leaving a big fat inheritance to your middle-aged children to confirm them in their worldliness.

He summarizes a vast area of truth in two rather shocking statements: Theology can conquer biology. Justification can conquer fornication. I've never seen it put that way before, but it certainly strikes me as a biblical formulation. Note that he doesn't say "theology will conquer biology," as if victory over sin is automatic. Theology provides the foundation and justification puts in you a position to receive God's life-changing power, but then you must fight and fight hard and keep on fighting, knowing that sometimes you will fail. What then? Either you give in (which is what the advocates of homosexuality support) or you stand and fight in Jesus' name, fighting in the power of the Lord but fighting nonetheless. Piper again:

The distinguishing mark of saving faith is not perfection. The mark of faith is not that I never sin sexually. The mark of faith is that I fight. I fight anything that dims my sight of Jesus as my glorious Savior. I fight anything that diminishes the fullness of the lordship of Jesus in my life. I fight anything that threatens to replace Jesus as the supreme Treasure of my life. Anything that stands between me and receiving Jesus. Faith fights -- not with fists or knives or guns or bombs, but with the truth of Christ.
