Now we, brothers, like Isaac, are children of the promise.
You are the sons of the prophets and of the covenant that God made with our fathers when he said to Abraham, ‘In yoʋr offspring all the families of the earth will be blessed.’
and not all of Abraham's children are his true descendants, but, “Through Isaac yoʋr descendants will be counted.”
And if you belong to Christ, then you are Abraham's descendants and heirs according to the promise.
But the son of the slave woman was born according to the flesh, while the son of the free woman was born through the promise.
The grace of our Lord Jesus Christ be with your spirit, brothers. Amen.
