¹⁵ Brothers and sisters, I’ll use an example from human experience. No one ignores or makes additions to a validated will. ¹⁶ The promises were made to Abraham and to his descendant. It doesn’t say, “and to the descendants,” as if referring to many rather than just one. It says, “and to your descendant,” who is Christ. ¹⁷ I’m saying this: the Law, which came four hundred thirty years later, doesn’t invalidate the agreement that was previously validated by God so that it cancels the promise. ¹⁸ If the inheritance were based upon the Law, it would no longer be from the promise. But God has given it graciously to Abraham through a promise.
