David was one man personally and intimately aware of the deep darkness that lurks within the human heart. He had, himself, sunk to depths of depravity he would have never thought possible as a harp playing, shepherd boy. But situations, opportunities and regal power had brought to the surface the gruesome reality of the human heart condition.
When Jeremiah said, “The heart is more deceitful than all else and is desperately sick; who can understand it?” (Jer. 17:9) he spoke like an insurance adjuster who writes of a damaged vehicle as a total loss. There seemed to be no hope for salvaging some good thing in it. Paul declared, “I know that nothing good lives in me”. And in Psalms reads, “All have turned aside, they have together become corrupt; there is no one who does good, not even one”.
I used to think that when David prayed, “Create in me a clean heart, O God…” he was asking God to clean his heart. Suddenly I realized that I had been reading it all wrong! David is not asking God to clean his heart, but rather to create a new clean heart…one that will replace the hopeless, desperate, unmitigated disaster he was born with. David wastes no time asking God to heal his old diseased heart. Instead he asks for a new one…a clean one. Such a thing, only God could create…….
