Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins. Not that we loved God - And that he was thereby induced to give his Son to be a propitiation for our sins. No: we were enemies to God, and yet Christ died for our ungodly souls. (See Romans 5:6-11, and the notes there.) So it was God's love, not our merit, that induced him to devise means that his banished might not be expelled from him.
