Romans 15:15-17

15Yet I have written you quite boldly on some points to remind you of them again, because of the grace God gave me

16to be a minister of Christ Jesus to the Gentiles. He gave me the priestly duty of proclaiming the gospel of God, so that the Gentiles might become an offering acceptable to God, sanctified by the Holy Spirit. 17Therefore I glory in Christ Jesus in my service to God.
