13-14Christ redeemed us from that self-defeating, cursed life by absorbing it completely into himself. Do you remember the Scripture that says, "Cursed is everyone who hangs on a tree"? That is what happened when Jesus was nailed to the cross: He became a curse, and at the same time dissolved the curse. And now, because of that, the air is cleared and we can see that Abraham's blessing is present and available for non-Jews, too. We are all able to receive God's life, his Spirit, in and with us by believing—just the way Abraham received it.
15-18Friends, let me give you an example from everyday affairs of the free life I am talking about. Once a person's will has been ratified, no one else can annul it or add to it. Now, the promises were made to Abraham and to his descendant. You will observe that Scripture, in the careful language of a legal document, does not say "to descendants," referring to everybody in general, but "to your descendant" (the noun, note, is singular), referring to Christ. This is the way I interpret this: A will, earlier ratified by God, is not annulled by an addendum attached 430 years later, thereby negating the promise of the will. No, this addendum, with its instructions and regulations, has nothing to do with the promised inheritance in the will.
