Charles Williams has said of the Lord's Prayer, "No word in English carries a greater possibility of terror than the little word 'as' in that clause." What makes the 'as' so terrifying? The fact that Jesus plainly links our forgiven-ness by the Father with our forgiving-ness of fellow human beings. Jesus' next remark could not be more explicit: 'If you do not forgive men their sins, your Father will not forgive your sins.'

Jesus never met a disease he could not cure, a birth defect he could not reverse, a demon he could not exorcise. But he did meet skeptics he could not convince and sinners he could not convert. Forgiveness of sins requires an act of will on the receiver's part, and some who heard Jesus' strongest words about grace and forgiveness turned away unrepentant.

Forgiveness is the only way to break the cycle of blame-and pain-in a relationship...It does not settle all questions of blame and justice and fairness...But it does allow relationships to start over. In that way, said Solzhenitsyn, we differ from all animals. It is not our capacity to think that makes us different, but our capacity to repent, and to forgive.

We preach sermons, write books on apologetics, conduct city-wide evangelistic campaigns. For those alienated from the church, that approach no longer has the same drawing power. And for the truly needy, words alone don't satisfy; "A hungry person has no ears," as one relief worker told me. A skeptical world judges the truth of what we say by the proof of how we live.

If prayer stands as the place where God and human beings meet, then I must learn about prayer. Most of my struggles in the Christian life circle around the same two themes: why God doesn't act the way we want God to, and why I don't act the way God wants me to. Prayer is the precise point where those themes converge.

We should be asking: How do we respond to a post-Christian society?

Some things just have to be believed to be seen.
