8 That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
–“The children of the promise are counted for the seed”. The seed being referenced here is the seed of Abraham. The Hebrew people, the bloodline of Abraham, are counted as the covenant people of God. Paul is telling the church that we too have been brought into that covenant. Not because of who we are or where we’ve come from, but because God extended unto us a promise: John 1:11-13 “He came unto his own, and his own received him not. But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.” It is said that blood is thicker than water, but if your eternal soul is at stake; would you rather be bound by blood or bound by the promise of God Himself?
