9 As a Christian, I’m telling you the truth. I’m not lying. The Holy Spirit, along with my own thoughts, supports me in this. 2 I have deep sorrow and endless heartache. 3 I wish I could be condemned and cut off from Christ for the sake of others who, like me, are Jewish by birth. 4 They are Israelites, God’s adopted children. They have the Lord’s glory, the pledges,[a] Moses’ Teachings, the true worship, and the promises. 5 The Messiah is descended from their ancestors according to his human nature. The Messiah is God over everything, forever blessed. Amen.
6 Now it is not as though God’s word has failed. Clearly, not everyone descended from Israel is part of Israel 7 or a descendant of Abraham. However, as Scripture says, “Through Isaac your descendants will carry on your name.” 8 This means that children born by natural descent from Abraham are not necessarily God’s children. Instead, children born by the promise are considered Abraham’s descendants.
9 For example, this is what the promise said, “I will come back at the right time, and Sarah will have a son.” 10 The same thing happened to Rebekah. Rebekah became pregnant by our ancestor Isaac. 11 Before the children had been born or had done anything good or bad, Rebekah was told that the older child would serve the younger one. This was said to Rebekah so that God’s plan would remain a matter of his choice, 12 a choice based on God’s call and not on anything people do. [b] 13 The Scriptures say, “I loved Jacob, but I hated Esau.”
14 What can we say—that God is unfair? That’s unthinkable! 15 For example, God said to Moses, “I will be kind to anyone I want to. I will be merciful to anyone I want to.”
