It was from God's promise. I have just read the whole of it. My understanding of it is more in depth, but I now know the meaning at a higher level so disregard the previous post. How I had interpretted what I heard is a little different now that I have read it. His meaning to me is clear. I understand. It was interesting reading about David, the type of person he was and how he really didn't think that much of himself. He praised God so much and thanked him for all he had done and was always looking for ways to repay Him. God's response was to not have to repay Him, but know Him. Know his will and do His bidding. Me and David from the Bible had some in common.
