He fulfilled the law. Man cannot keep the law. He fulfilled the law. He bore as our sin. It's like we put our hands on him. We trust him. All our sins transferred to him, and he bore the judgment of God. One stroke of the broken law, one curse after another fell upon him, stroke after stroke after stroke, until every stroke was exhausted in the person of Christ, and he shouted, "Finished," "kulah" in Hebrew, "Finished". There's no more judgment from God for you if you believe in him and what he's done.
