Romans 15:13-19

May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit.

I myself am convinced, my brothers and sisters, that you yourselves are full of goodness, filled with knowledge and competent to instruct one another. Yet I have written you quite boldly on some points to remind you of them again, because of the grace God gave me to 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.
Therefore I glory in Christ Jesus in my service to God. I 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— by 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.
