Romans 9:6-8

Romans 9:6-8 NASB1995

But it is not as though the word of God has failed. For they are not all Israel who are descended from Israel; nor are they all children because they are Abraham’s descendants, but: “THROUGH ISAAC YOUR DESCENDANTS WILL BE NAMED.” That is, it is not the children of the flesh who are children of God, but the children of the promise are regarded as descendants.
