What, then, has He who is Love, and therefore must save, done to restore His lost humanity to Himself?
He has taken flesh Himself to start a new race. In the Person of His Son, Jesus, He came into history as a man called “the last Adam,” the Creator of the first. Having lived a perfect life which the first Adam failed to live, He then identified Himself totally with the fallen human race by dying for us. In that death He was so identified with us all in God’s sight that the Bible says, “He made Him to be sin for us, who knew no sin. Thus, He died. In doing so, the Bible reveals that He effected the two supreme deliverance’s that were the two absolute necessities.
First, He solved God’s problem (or rather, God solved His own problem) by taking upon Himself the curse of the broken law, and being made a curse for us. By the shedding of His blood, His out-poured life, He became God’s “mercy seat.”
By this, God could both be just and justify the ungodly, and pronounce all believers in Jesus justified from all unrighteousness-for-given, cleansed, in His sight as if we had committed no sin; “made the righteousness of God in Him.” Broken law has consequences. That is the nature of law. God, farseeing that we should all be lawbreakers, foreordained His Son to be “the propitiation through faith in His blood.”
What God revealed to be the necessary atonement for sin, He Himself suffered. What He suffered He accepted. And His acceptance is our justification (as the Scripture says, “raised again for our justification”). What is good enough for God is good enough for us. “How much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot unto God, purge your conscience from dead works to serve the living God?”
Secondly, Christ’s cross and resurrection solved our problem. For by this means He fully effected the destruction of the old union of humanity to Satan and replaced it by the new union to Himself.
Our problem is simply that in our unredeemed life our inner self, our spirit, was united to the self-loving spirit of Satan.
As a consequence, we followed the desire of soul and body. When our bodies stimulated appetites in us, we gratified them. When our souls stirred up pride or dislike of this or hate of that or love of that—we just followed them.
We were governed by our souls and bodies.
