Romans 15:17-19

Therefore I have reason to glory in Christ Jesus in the things which pertain to God. For I will not dare to speak of any of those things which Christ has not accomplished through me, in word and deed, to make the Gentiles obedient— in mighty signs and wonders, by the power of the Spirit of God, so that from Jerusalem and round about to Illyricum I have fully preached the gospel of Christ.
