Now we, brothers, like Isaac, are the children of promise.
And behold, the word of the Lord came to him, saying, “This man will not be your heir, but a son that is from your own body will be your heir.”
You are the sons of the prophets and of the covenant which God made with our fathers, saying to Abraham, ‘And in your seed shall all the families of the earth be blessed.’
nor are they all children because they are descendants of Abraham, but “In Isaac shall your descendants be called.”
If you are Christ’s, then you are Abraham’s seed, and heirs according to the promise.
But he who was of the slave woman was born according to the flesh, but he of the free woman through the promise.
Brothers, the grace of our Lord Jesus Christ be with your spirit. Amen.
