What did Jesus do as the perfect sacrifice?
Jesus, as the perfect sacrifice, fulfilled all the demands of a holy God. He is the just one and also the holy God, so He is both the justifier and the sacrifice. Those who believe in Jesus the Christ, the resurrected one, are justified.
Les explains that He has done it all from both directions. He is the whole tabernacle, just as well as the justifier. He is not only the just one who was the perfect sacrifice, fulfilling all the demands of a holy God, but He is also the holy God. Then He is the justifier of him who believes now in Jesus, or as Paul normally puts it, in Jesus the Christ, the resurrected one.
