You do understand that there is no cuch thing as "the Covenant of Grace," despite any spin/lies, to the contrary?
I'll have to beg to differ on that, where God's relationship with Abraham, Isaac, and Jacob as to a MULTIPLIED seed out of them that one day WILL serve HIM, is concerned.
What then was this that Moses reminded the LORD of, when He was about to wipe out Israel based on their works?
Exodus 32:7 And the LORD said unto Moses, Go, get thee down; for thy people, which thou broughtest out of the land of Egypt, have corrupted themselves: 32:8 They have turned aside quickly out of the way which I commanded them: they have made them a molten calf, and have worshipped it, and have sacrificed thereunto, and said, These be thy gods, O Israel, which have brought thee up out of the land of Egypt. 32:9 And the LORD said unto Moses, I have seen this people, and, behold, it is a stiffnecked people: 32:10 Now therefore let me alone, that my wrath may wax hot against them, and that I may consume them: and I will make of thee a great nation. 32:11 And Moses besought the LORD his God, and said, LORD, why doth thy wrath wax hot against thy people, which thou hast brought forth out of the land of Egypt with great power, and with a mighty hand? 32:12 Wherefore should the Egyptians speak, and say, For mischief did he bring them out, to slay them in the mountains, and to consume them from the face of the earth? Turn from thy fierce wrath, and repent of this evil against thy people. 32:13 Remember Abraham, Isaac, and Israel, thy servants, to whom thou swarest by thine own self, and saidst unto them, I will multiply your seed as the stars of heaven, and all this land that I have spoken of will I give unto your seed, and they shall inherit it for ever. 32:14 And the LORD repented of the evil which he thought to do unto his people.
Clearly, the LORD was once more setting a precedent by which to view God's dealiings with Israel - that theirs is a Covenant of Grace.
It is why the the Replacemetists are wrong.
God Himself portrayed Himself for a moment a Replacementist that day at Sinai to establish in the Law - that's right - in - the - Law - itself - and once and for all - that He will NEVER be through with the sons of Jacob.
Because His Covenant unto Abraham, Isaac, and Jacob concerning a MULTIPLIED seed that one day WILL serve HIM - was a Covenant of Grace UNTO and concerning - THEM.
That is what all this, is...
Malachi 3:6 For I am the LORD, I change not; therefore ye sons of Jacob are not consumed.
Romans 9:11 (For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth; )
Romans 11:5 Even so then at this present time also there is a remnant according to the election of grace.
11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
As works is not of grace, neither is grace, of works.
Or, grace is no more of works, than works is of grace.
Neither the twain, shall meet.
Malachi 3:6 For I am the LORD, I change not; therefore ye sons of Jacob are not consumed.
