Temptation, in and of itself, is not sin. This is critically important, especially for those who suffer from an overly sensitive and tender conscience. Jesus was repeatedly tempted (Heb. 2:17-18; 4:15; Mt. 4), but he was sinless. We must resist thinking that we are sub-Christian or sub-spiritual simply because we are frequently tempted. It was the great reformer Martin Luther who first said, “You can't prevent the birds from flying over your head, but you can keep them from building a nest in your hair.” His point is that a temptation only becomes a sin when you acquiesce to it, as it were “fondle” it and “enjoy” it.
