14 so that the blessing of Abraham might come on the Gentiles through Jesus Christ, that we might receive the promise of the Spirit through faith.
15 Brothers, I am speaking in human terms: Though it is only a man’s covenant, yet if it is ratified, no one annuls or adds to it.
16 Now the promises were made to Abraham and his Seed. He does not say, “and to seeds,” meaning many, but “and to your Seed,” meaning one, who is Christ.
17 And this I say, that the law, which came four hundred and thirty years later, does not annul the covenant that was ratified by God in Christ, so as to nullify the promise.
18 For if the inheritance comes from the law, it no longer comes from the promise. But God gave it to Abraham through a promise.
19 What purpose then does the law serve? It was added because of transgressions, until the Seed should come to whom the promise was made. And it was ordained through angels by the hand of a mediator.
20 Now a mediator is not a mediator for only one party, but God is one.
