Evolutionary tendencies.

"People do not drift toward holiness. Apart from grace-
driven effort, people do not gravitate toward godliness,
prayer, obedience to Scripture, faith, and delight in the Lord.
We drift toward compromise and call it tolerance; we drift
toward disobedience and call it freedom; we drift toward
superstition and call it faith. We cherish the indiscipline of
lost self-control and call it relaxation; we slouch toward
prayerlessness and delude ourselves into thinking we have
escaped legalism; we slide toward godlessness and convince
ourselves we have been liberated."
