Surely for my own welfare I had such great anguish; but Your love has delivered me from the pit of oblivion, for You have cast all my sins behind Your back. — Isaiah 38:17

"In love to my soul You delivered it from the pit of corruption". Hezekiah's song of healing points beyond itself to a greater deliverance. God sent His Son as the propitiation for our sins—that's love, not our love for Him but His love for us. Micah 7:18-19 asks "Who is a God like You, pardoning iniquity?"—He casts our sins into the depths of the sea. He lifted me from the pit of destruction and set my feet on a rock.
