He has given us the power to serve under a new covenant. It’s not based on the written Law of Moses; it comes from the Holy Spirit. The written Law kills, but the Spirit gives life.
That’s why the good news was preached even to people who are now dead. Even though they were judged in their bodies for what they did while they lived on earth, they were told the good news so that they could live in the spirit the way God wants.
We’re the ones who have truly been circumcised: We serve God by his Spirit, we boast in Christ Jesus, and we don’t put our trust in who we are or what we can do—although I myself could do that for many reasons.
