Brothers, speaking of human terms, though it is only a man’s covenant, yet when it has been confirmed, no one makes it void or adds to it.
Now the promises were spoken to Abraham and to his offspring.
He doesn’t say, “To descendants”, as of many, but as of one, “To your offspring”, which is Christ.
Now I say this: A covenant confirmed beforehand by God in Christ, the law, which came four hundred thirty years after, does not annul, so as to make the promise of no effect.
