Romans 15:19

19 by the power of signs and wonders, by the power of the Holy Spirit, so that from Jerusalem and as far round as Illyr'icum I have fully preached the gospel of Christ,

Romans 15:19 In-Context

17 In Christ Jesus, then, I have reason to be proud of my work for God.
18 For I will not venture to speak of anything except what Christ has wrought through me to win obedience from the Gentiles, by word and deed,
19 by the power of signs and wonders, by the power of the Holy Spirit, so that from Jerusalem and as far round as Illyr'icum I have fully preached the gospel of Christ,
20 thus making it my ambition to preach the gospel, not where Christ has already been named, lest I build on another man's foundation,
21 but as it is written, "They shall see who have never been told of him, and they shall understand who have never heard of him."
