¹⁶ God made his promises to Abraham and to his Son. The promise does not have the words, `and to his sons,' for that means many sons. But it says, `and to his Son,' and that Son is Christ.

¹⁷ Here is what I mean. The law was given [to Moses] four hundred and thirty years after God gave that promise to Abraham. But it cannot break the strong promise which God made. And the law cannot change God's promise.

¹⁸ Do we get what God has promised us by obeying the law? If we do, then we are not getting it by his promise. But God gave it to Abraham by his promise.
