Romans 9:1-9

I say the truth in Christ, I lie not, my conscience bearing witness with me in the Holy Spirit, that I have great sorrow and unceasing pain in my heart. For I could wish that I myself were anathema from Christ for my brethren’s sake, my kinsmen according to the flesh: who are Israelites; whose is the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises; whose are the fathers, and of whom is Christ as concerning the flesh, who is over all, God blessed for ever. Amen. But it is not as though the word of God hath come to nought. For they are not all Israel, that are of Israel: neither, because they are Abraham’s seed, are they all children: but, In Isaac shall thy seed be called. That is, it is not the children of the flesh that are children of God; but the children of the promise are reckoned for a seed. For this is a word of promise, According to this season will I come, and Sarah shall have a son.
