He simply wasn't all there. He wasn't a complete human being at all. A tiny bit of a man pretending he was the whole. That description fits far too many people in this material-minded world.
Integrity means wholeness.
We cannot be whole human beings, complete human beings, fulfilled human beings . . . That He keeps us in being. That we are destined for union with Him. That He has given us His Son, Jesus Christ, for our ideal and model. Integrity just isn't possible unless we are prepared to live our lives in the light of those truths.
