Psalm 41:10 But thou, O Lord, be merciful unto me, and raise me up, that I may requite them.
David is facing evil enemies, disease, and betrayal, and in his need he prays to the Lord that He would be merciful to him and raise him up, thereby saving him from the enemies of sin, death, and the devil.
During this life, we, too, frequently come under attack from our spiritual enemies that make us feel weak, guilty, and scared. But the mercy of God is shown to us in the life, death, and resurrection of His Son, Jesus Christ. Because of Christ, by grace, through faith, He grants mercy to us. The blood of Jesus is the mercy of God. We remember who Jesus is and what He did for us, and we plead the blood in Jesus’ name. By faith we receive mercy and apply it to our present need and particular situation. Such mercy is near to us and always available to us.
