Romans 15:19-21

by the power of signs and wonders, through the power of the Spirit of God. So from Jerusalem all the way around to Illyricum, I have fully proclaimed the gospel of Christ. It has always been my ambition to preach the gospel where Christ was not known, so that I would not be building on someone else’s foundation. Rather, as it is written: “Those who were not told about him will see, and those who have not heard will understand.”
