The Drifting Life, by William Barclay

There are few people who deliberately and in a moment turn their backs on God; there are many who day by day drift farther and farther away from Him. There are not many who in one moment of time commit some disastrous sin; there are many who, but by bit and almost imperceptibly, involve themselves in some situation, and suddenly awake to find that they have ruined life for themselves and broken someone else's heart. We would do well to be continually on the alert against the peril of the drifting life.
