BEHAVIOR

There's little difference in ethical behavior between the churched and the unchurched. There's as much pilferage and dishonesty among the churched as the unchurched. And I'm afraid that applies pretty much across the board: Religion, per se, is not really life changing. People cite it as important, for instance, in overcoming depression--but it doesn't have primacy in determining behavior.

In his book I Surrender, Patrick Morley writes that the church's integrity problem is in the misconception "that we can add Christ to our lives, but not subtract sin. It is a change in belief without a change in behavior." He goes on to say, "It is revival without reformation, without repentance."
