Romans 15:17-19

In Christ Jesus, then, I have found [legitimate] reason for boasting in things related [to my service] to God. For I will not [even] presume to speak of anything except what Christ has done through me [as an instrument in His hands], resulting in the obedience of the Gentiles [to the gospel], by word and deed, with the power of signs and wonders, [and all of it] in the power of the Spirit. So [starting] from Jerusalem and as far away as Illyricum, I have fully preached the gospel [faithfully preaching the good news] of Christ [where it had not before been preached].
