God’s promise in Jeremiah 31:34 is, “. . . I will forgive their iniquity, and I will remember their sin no more.”
“The Lord will make an act of indemnity. He will not upbraid us with former unkindness, nor sue us with a cancelled bond. ‘He will cast all our sins into the depths of the sea’ (Micah 7:19). Sin shall not be cast in like cork which rises up again, but like lead which sinks to the bottom. How we should all labour for this covenant blessing!”
