Psalm 6
It seems that David knew he had done something wrong, something against the Lord, though we are given no indication of what. Whatever the details David asks the Lord not to rebuke him in His anger, but instead to have mercy on Him. We are all reliant upon the Lord treating us with mercy, David was not feeling good, he felt faint, and his bones were in agony. Moreover his soul was in anguish. Many of us go through times of feeling terrible, there is nothing unusual about this. We, like David, may wonder “how long?” David calls upon the Lord to deliver him on the basis of His “unfailing love”. He reminds God that the dead do not praise Him. We are more likely to praise the Lord when we are well than we are under pressure.
David was having a very difficult time, but he knew that the Lord had heard him and would answer his prayers. It is his enemies who would be put to shame. The unfailing love of the Lord is our strength and security.
