Oooo, "replacement theology." No, it doesn't work that way.
Just what Law do you think Jesus might have been talking about? Why, the Law of the Father. That would be the Torah. Follow Him, and you choose to follow the Law of Moses, your works according to which you will be judged. Don't think works matter?
Nothing 'replaced' at all; but merely pointing out the facts of the matter.
I can post Acts 15 if you wish.
Jesus answered, The work of God is this: to believe in the one he has sent.
Yes, we are saved by grace, but we are KEPT by works, according to a LOT of 'christian' teachings these days!
