Romans 8:2 For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and of death. 3 For what the Law could not do, weak as it was through the flesh, God did: sending His own Son in the likeness of sinful flesh and as an offering for sin, He condemned sin in the flesh, 4 so that the requirement of the Law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit.…

The requirement of the law was "perfection". Man was never going to make the grade...never could, never will be able to....only Jesus Christ could do that...and he did it for us. It's done.
