The Messiah is the Redeemer. He is the Law - the one who holds the keys to the jail. Nobody gets past him. Noone goes in, noone goes out without his authority.
So in a flipped over way, the Law does indeed save, because he is the Law. Those who are forgiven much, love much. There is everything to love about him for what he did. Well not for the individual benefit of the sacrifice per se, but for the soul behind the actions, the one who was willing to die for his friends. Same way people should know that it is the tree that provides the shade from the hot summer sun, not the shadow itself. No tree, no shade.
As it is axiomatic that laws die with the deceased, a soul is not a soul unless it is alive. Now if people would be grateful for his raising of the dead to life, they'd love others as they were loved by God and by him. Somehow that simple message got trampled to death on the doctrinal battlegrounds of perceived wisdom..
Jer 31
32. But this shall be the covenant that I will make with the house of Israel; After those days, says the Lord, I will put my Torah in their inward parts, and write it in their hearts; and will be their God, and they shall be my people:
33. And they shall teach no more every man his neighbor, and every man his brother, saying, Know the Lord; for they shall all know me, from the least of them to the greatest of them, says the Lord; for I will forgive their iniquity, and I will no longer remember their sin:
And they shall teach no more every man his neighbor, and every man his brother, saying, Know the Lord
There goes the religion forum!
For what is easier, to say, 'Know the Lord', or to say 'I love you'?
But that you may know the Lord, say, "I love you."
Easy to out a liar with that one, because love doesn't DO what many religion forum posters do to each other on a daily dysfunctional basis.
No, the Law does not save. It never has and never will.
The Law points us to our need for Christ, that the atonement and forgiveness that is freely given to us who break the Law will be credited to our account when we throw ourselves on the mercy of the court and simply believe what God told us and trust Him to do it.
