When real repentance is expressed and faithfully explained, it shatters so much of popular preaching, thinking, and assumptions.
Is God an incompetent physician who misdiagnoses the key problem, then performs radical, invasive surgery on a functional organ that was unnecessary? If YES, then David’s desperate plea for a new heart becomes meaningless. But if God knows the correct diagnosis and cure as well as the only valid remedy, Psalm 51 and more – suddenly make perfect sense.
