Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, “Cursed is everyone who hangs on a tree”), that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith. Brethren, I speak in the manner of men: Though it is only a man’s covenant, yet if it is confirmed, no one annuls or adds to it. Now to Abraham and his Seed were the promises made. He does not say, “And to seeds,” as of many, but as of one, “And to your Seed,” who is Christ. And this I say, that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ, that it should make the promise of no effect. For if the inheritance is of the law, it is no longer of promise; but God gave it to Abraham by promise. What purpose then does the law serve? It was added because of transgressions, till the Seed should come to whom the promise was made; and it was appointed through angels by the hand of a mediator. Now a mediator does not mediate for one only, but God is one. Is the law then against the promises of God? Certainly not! For if there had been a law given which could have given life, truly righteousness would have been by the law. But the Scripture has confined all under sin, that the promise by faith in Jesus Christ might be given to those who believe. But before faith came, we were kept under guard by the law, kept for the faith which would afterward be revealed. Therefore the law was our tutor to bring us to Christ, that we might be justified by faith. But after faith has come, we are no longer under a tutor. For you are all sons of God through faith in Christ Jesus. For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus. And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise.
Galatians 3:13-29 NKJV
So what do we do? Keep on sinning so God can keep on forgiving? I should hope not! If we’ve left the country where sin is sovereign, how can we still live in our old house there? Or didn’t you realize we packed up and left there for good? That is what happened in baptism. When we went under the water, we left the old country of sin behind; when we came up out of the water, we entered into the new country of grace—a new life in a new land! That’s what baptism into the life of Jesus means. When we are lowered into the water, it is like the burial of Jesus; when we are raised up out of the water, it is like the resurrection of Jesus. Each of us is raised into a light-filled world by our Father so that we can see where we’re going in our new grace-sovereign country.
