David is “lonely and afflicted” (v. 16). He’s surrounded by his enemies. His heart accuses him. His mind is haunted by the memory of his past sins. He has nowhere in this world to turn. So, he turns to God, saying, “To you, O Lord, I lift up my soul. O my God, in You I trust,” (v. 1), “My eyes are ever toward the Lord” (v. 15), “I take refuge in You” (v. 20). And the consolation David seeks for his heart is this: The forgiveness of all his sins (v.18).
