I don't need to read it again. I've already highlighted what it says:
Galatians 3:17
17 And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.
Galatians 3:19
19 Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.
I would like for YOU to give me one reason to believe YOU. Show me some scripture which shows the Mosaic Law was a new covenant - and good luck with that. The law is NOT a covenant.
Maybe we should address another question. What do you believe the new covenant with Jesus is?
When we speak of the new covenant we are speaking of the covenant Jeremiah spoke of which came in Jesus.
The Law of Moses is associated with the covenant God made with the nation of Israel.
