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.
Live in a way that shows you’ve turned away from your sins, and don’t start saying to yourselves, ‘Abraham is our father.’ I tell you, God can raise up children for Abraham even from these stones.
