God forgave sins all through the Old Testament — so what exactly did the cross ADD that God couldn't already do on His own?
David murdered a man, committed adultery, and was forgiven with no crucifixion in sight. The whole sacrificial system in Leviticus was given specifically to cover sin — centuries before Calvary. So if God was already forgiving people left and right in the Old Testament, what is the cross actually doing that God wasn't already perfectly capable of doing? Pick a side: is the cross the only way sins are ever truly forgiven, or has that always been God's choice to make — and the cross is something else entirely?
