Romans 15:18-21

18For 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, 19Through mighty signs and wonders, by the power of the Spirit of God; so that from Jerusalem, and all around to Illyricum, I have fully preached the gospel of Christ. 20And, so have I strived to preach the gospel, not where Christ was named, lest I should build upon another man’s foundation: 21But as it is written, They shall see to whom he was not spoken of: and they that have not heard shall understand.
