I just quoted you some verses from scripture that shows us how:And can anyone keep the Law perfectly, this side of heaven? Remember, we are by nature "children of wrath."
So, how do we keep the Law perfectly now? Remember, James says if we break one law, we are guilty of ALL of it.
Romans 8:2-4, "For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and of death. For God has done what the law, weakened by the flesh, could not do: by sending his own Son in the likeness of sinful flesh, and to deal with sin, he condemned sin in the flesh, so that the just requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit."
Under the NC God is putting his laws in our minds and writing them in our hearts. God is making it possible for us to keep the law if we walk according to the Spirit and not the flesh.
