God never lies, but that does not mean you are hearing him accurately.
As He says also in Hosea: "I will call them My people, who were not My people, And her beloved, who was not beloved." "And it shall come to pass in the place where it was said to them, 'You are not My people,' There they shall be called sons of the living God." (Rom. 9:25,26)All those who trust in the living God by the blood of Messiah, Jesus Christ, are God's people. There is no more racial distinction.For you (the Church) are the temple of the living God. As God has said: "I will dwell in them And walk among them. I will be their God, And they shall be My people." (1 Cor. 6:16)
Jeremiah 31
31Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
32Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
33But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
35Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name:
36If those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever.
37Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD.
So, is the seed of Israel ever cast off? Is it ever ended? Wasn't tis written 500 to 600 years before Christ? Wasn't it written to genetic Jews, not Jews in name only?
