You might want to keep reading a little further….
Romans 3:31 Do we then make void the law through faith? Certainly not! On the contrary, we establish the law.
Reading further does not make this law, Sinai law. It still concerns the law of faith that Abraham, Isaac and Jacob walked in.
Deut 5:2 The LORD our God made a covenant with us in Horeb.
3 The LORD
made not this covenant with our fathers, but with us, even us, who are all of us here alive this day.
4 The LORD talked with you face to face in the mount out of the midst of the fire,
Paul is not deleting the commandments of God here as he tells us what matters is keeping the commandments of God. 1 Cor 7:19
Why do you think, I think Paul is abolishing God's commandments? And what makes you think the law which Abraham Kept was not retained in Moses law?
Of course it was retained since it could not be disanulled by the covenant given 430 years later. Indeed, Sinai law was
ADDITIONAL to it....
Ga 3:19 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. The Christ, the royal seed in the promise made to Abraham and Sarah...
Ge 26:5 Because that Abraham obeyed my voice, and kept my charge,
my commandments, my statutes, and my laws.
It was Sinai, which was 430 after...
Ge 18:19 For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.
Ga 3:17 And this I say, that, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.
The above concerns the Gospel which was preached before Sinai, to Abraham. It was in covenant with Abraham, and confirmed much earlier.
Furthermore............
Abraham Instructed all his household in it...
Ge 18:19 For I know him, that
he will command his children and his household after him, and
they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.
God’s saints have both the faith in Jesus and keep the commandments of God Revelations 14:12
Yep, by the gospel in Christ which the law (of Sinai) which was 430 years after cannot disannul...
True faith means we want to believe the Words of our Savior and have His laws written in our hearts and minds and we fulfill those laws and show faith when we obey not disobey.
Just like Abraham.
Do you even notice The covenant God made with Abraham in Genesis 17? The annointed ones are..
1. Prophets
2. Kings
3. Priests
The covenant made with Abraham
in Christ, was of kings
Sarah an allegory.....Kings, Royal seed....
Ge 17:6 And I will make thee exceeding fruitful, and I will
make nations of thee, and kings shall come out of thee.
Ge 17:16 And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be
a mother of nations; kings of people shall be of her.
Hagar An allegory for Sinai..
Ge 17:20 And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly;
twelve princes shall he beget, and I will make him
a great nation.
