Romans 15:19-21

in the power of signs and wonders, in the power of the Holy Spirit; so that from Jerusalem, and round about even unto Illyricum, I have fully preached the gospel of Christ; yea, making it my aim so to preach the gospel, not where Christ was already named, that I might not build upon another man’s foundation; but, as it is written, They shall see, to whom no tidings of him came, And they who have not heard shall understand.
