BSB(i)
14 He redeemed us in order that the blessing promised to Abraham would come to the Gentiles in Christ Jesus, so that by faith we might receive the promise of the Spirit.
15 Brothers, let me put this in human terms. Even a human covenant, once it is ratified, cannot be canceled or amended.
16 The promises were spoken to Abraham and to his seed. The Scripture does not say, “and to seeds,” meaning many, but “and to your seed,” meaning One, who is Christ.
17 What I mean is this: The law that came 430 years later does not revoke the covenant previously established by God, so as to nullify the promise.
