Romans 15:19

¹⁷  I have therefore whereof I may glory through Jesus Christ in those things which pertain to God.

¹⁸  For I will not dare to speak of any of those things which Christ hath not wrought by me, to make the Gentiles obedient, by word and deed,

¹⁹  Through mighty signs and wonders, by the power of the Spirit of God; so that from Jerusalem, and round about unto Illyricum, I have fully preached the gospel of Christ.

²⁰  Yea, so have I strived to preach the gospel, not where Christ was named, lest I should build upon another man's foundation:

²¹  But as it is written, To whom he was not spoken of, they shall see: and they that have not heard shall understand.
