Wisdom is defined in Proverbs 1 as understanding the consequences & dead-end that the road of sin takes us down. It's foreseeing the pain, suffering and inner destruction that sin surely causes. Self-Deception is just the opposite; denying the inevitable. The exits on the road to destruction are clearly marked. Living in daily wisdom takes the punch out of temptation and a daily Cross causes us to live in the New because old things are passed away.
