Romans 15:16-19

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. 18I will not venture to speak of anything except what Christ has accomplished through me in leading the Gentiles to obey God by what I have said and done— 19by the power of signs and wonders, through the power of the Spirit of God. So from Jerusalem all the way around to Illyricum, I have fully proclaimed the gospel of Christ.
