What does Psalm 51:14 mean?
David asks the Lord to deliver him from "bloodguiltiness:" a fancy term for murder. David felt he had Uriah's blood on his hands. Although David had committed adultery and murder, he still belonged to God. He calls Him the God of his salvation. The fact that David felt so guilty about his sin and confessed it shows that he still belonged to God.Can God forgive even a murderer? The repentant thief on the cross was an insurrectionist who may have committed murder, but when he urged Jesus to remember him in His kingdom, Jesus promised, "Truly, I say to you, today you will be with me in paradise" (Luke 23:39–43). Also, God saved Saul of Tarsus, who consented to Stephen's martyrdom,(Acts 7:58; 8:1). In Galatians 1:13, the apostle Paul, formerly that same Saul of Tarsus, admitted he had "persecuted the church of God violently and tried to destroy it." Nevertheless, God saved him (Galatians 1:15–16).
Here in this verse, David promises to celebrate forgiveness by singing aloud about God's righteousness. We, too, should celebrate the grace that brings forgiveness by singing loudly about God's righteousness.
