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.

Romans 15:19

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.
