Christ Jesus became what we are not; He accomplished what we could not. He alone was capable of filling the role of the perfect sacrifice for sin, as well as becoming the Great High Priest interceding to carry out our redemption, both so skillfully described in the book of Hebrews. Here’s how Paul describes it in Romans:
“Now if we have died with Christ, we believe that we shall also live with Him, knowing that Christ, having been raised from the dead, is never to die again; death no longer is master over Him. For the death that He died, He died to sin once for all; but the life that He lives, He lives to God. Even so, consider yourselves to be dead to sin, but alive to God in Christ Jesus.” (Romans 6:8-11)
