Romans 15:19
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. 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.
Paul fully preached the gospel of Christ from Jerusalem and round about unto Illyricum, with Christ working through him to bring the Gentiles to obedience. That full preaching was accomplished through both his words and his deeds, in what he spoke and in what he did. Mighty signs and wonders accompanied his preaching, done by the power of the Spirit of God. Revelations from God also strengthened and confirmed his message, giving it immovable evidence. Fitness for such gospel service comes only when brain-power and the talent of speech are sanctified.
