Romans 15:8-9

15:8 For I tell you that Christ has become a servant of the circumcised on behalf of God’s truth to confirm the promises made to the fathers, 15:9 and thus the Gentiles glorify God for his mercy. As it is written, “Because of this I will confess you among the Gentiles, and I will sing praises to your name.”

Romans 15:16

15:16 to be a minister of Christ Jesus to the Gentiles. I serve the gospel of God like a priest, so that the Gentiles may become an acceptable offering, sanctified by the Holy Spirit.
