Galatians 3:15–18

15 Brothers and sisters, I’m using a human illustration. No one sets aside or makes additions to a validated human will.O 16 Now the promises were spoken to Abraham and to his seed. He does not say “and to seeds,” as though referring to many, but referring to one, and to your seed,P,at who is Christ. 17 My point is this: The law, which came 430 years later,au does not invalidate a covenant previously established by GodQ and thus cancel the promise. 18 For if the inheritance is based on the law, it is no longer based on the promise; but God has graciously given it to Abraham through the promise.
