You are the sons of the prophets and of the covenant that God made with your ancestors, saying to Abraham, ‘And in your descendants all the nations of the earth will be blessed.’
For the promise to Abraham or to his descendants that he would inherit the world was not fulfilled through the law, but through the righteousness that comes by faith.
Now the promises were spoken to Abraham and to his descendant. Scripture does not say, “and to the descendants,” referring to many, but “and to your descendant,” referring to one, who is Christ.
These all died in faith without receiving the things promised, but they saw them in the distance and welcomed them and acknowledged that they were strangers and foreigners on the earth.
