Romans 15:17-19

Therefore in Christ Jesus I have found reason for boasting in things pertaining to God. For I will not presume to speak of anything except what Christ has accomplished through me, resulting in the obedience of the Gentiles by word and deed, in the power of signs and wonders, in the power of the Spirit; so that from Jerusalem and round about as far as Illyricum I have fully preached the gospel of Christ.
