Romans 15:15-17
15:15 But I have written more boldly to you on some points so as to remind you, because of the grace given to me by God
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.
15:17 So I boast in Christ Jesus about the things that pertain to God.
