Try me. What variant of replacement theology do you subscribe to?
It’s pretty simple really, looking at the covenants. The first was predicated on acts. IF you’ll do THIS, then God will do THAT. These actions were to point to the coming Redeemer. To remind them the Messiah was coming. The new Covenant is God meeting us more than halfway. He will put a new heart in us inclined to want to do His will. If we truly love God, we will do His Commandments willingly. We will want to please Him because of His sacrifice. It will not be a burden (as the old covenant was). We will be inspired and liberated no matter what our circumstances. (For God is with us).
