Romans 15:16-19

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. 15:18 For I will not dare to speak of anything except what Christ has accomplished through me in order to bring about the obedience of the Gentiles, by word and deed, 15:19 in the power of signs and wonders, in the power of the Spirit of God. So from Jerusalem even as far as Illyricum I have fully preached the gospel of Christ.
