Galatians 3:16–18

Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ. This is what I mean: the law, which came 430 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void. For if the inheritance comes by the law, it no longer comes by promise; but God gave it to Abraham by a promise.

The promises were spoken to Abraham and to his seed. Scripture does not say “and to seeds,” meaning many people, but “and to your seed,” meaning one person, who is Christ. What I mean is this: The law, introduced 430 years later, does not set aside the covenant previously established by God and thus do away with the promise. For if the inheritance depends on the law, then it no longer depends on the promise; but God in his grace gave it to Abraham through a promise.

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, who is Christ. My point is this: The law, which came 430 years later, does not invalidate a covenant previously established by God and thus cancel the promise. 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.

God gave the promises to Abraham and his child. And notice that the Scripture doesn’t say “to his children,” as if it meant many descendants. Rather, it says “to his child”—and that, of course, means Christ. This is what I am trying to say: The agreement God made with Abraham could not be canceled 430 years later when God gave the law to Moses. God would be breaking his promise. For if the inheritance could be received by keeping the law, then it would not be the result of accepting God’s promise. But God graciously gave it to Abraham as a promise.

Now to Abraham and to his descendant the promises were spoken. It does not say, “and to descendants,” as concerning many, but as concerning one, “and to your descendant,” who is Christ. Now I am saying this: the law, that came after four hundred and thirty years, does not revoke a covenant previously ratified by God, in order to nullify the promise. For if the inheritance is from the law, it is no longer from the promise, but God graciously gave it to Abraham through the promise.

Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect. For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise.
