Psalm For The Fearful & Foolish

David acted like a mad man; like a crazy man; like he did not know the Lord. He was in a place he shouldn't have been, amongst heathen people, and he ended up looking and acting like a man who had lost his mind.
This story shows just what a believer is capable of; how a child of God, even a man like David, can get himself into such a deep hole and a bad way that it looks hopeless for him.
