Romans 15:19 means that Paul’s preaching of the gospel was carried out through the power of God, shown in signs and wonders and by the Holy Spirit, not through his own ability. Paul wrote this verse near the end of his letter to the church in Rome, reporting on the ministry he had done across the eastern Mediterranean.
In the power of signs and wonders, in the power of God’s Spirit; so that from Jerusalem, and around as far as to Illyricum, I have fully preached the Good News of Christ…

What Romans 15:19 Means
Paul begins by naming the source of his work: “in the power of signs and wonders, in the power of God’s Spirit.” He is not claiming credit for results. Whatever happened through his ministry, he attributes it to God’s active power, which he describes as both visible acts and the inward work of the Spirit.
The phrase “from Jerusalem, and around as far as to Illyricum” gives the geographic reach of his effort. Jerusalem was the starting point of the Christian mission, and Illyricum was a region on the far side of the Adriatic, roughly the western Balkans. Paul is describing a wide arc of territory that he considers fully covered by his preaching.
What the verse does not promise is a formula that guarantees the same outcome for every believer. Paul is speaking about his own calling as an apostle to the Gentiles. It is a report of God’s work through one servant, not a general pledge that signs will accompany every act of witness.
The Context of Romans 15:19
Paul wrote Romans around AD 56 or 57, most likely from Corinth, to a congregation in Rome that he had not yet visited. The church included both Jewish and Gentile believers, and much of the letter works to bring them into unity. Traditionally Paul is recognized as the author, and his audience’s mixed background shapes the whole discussion.
Just before verse 19, Paul describes himself as a priest serving the gospel so that the Gentiles might become an acceptable offering. Just after it, he says he aims to preach where Christ has not yet been named, and he links his plans to visit Rome. Read in that setting, the verse is Paul’s credential and his explanation for why he can now turn his attention westward, toward Rome and Spain.
Key Phrases in Romans 15:19
1 Corinthians 2:4-5
4 My speech and my preaching were not in persuasive words of human wisdom, but in demonstration of the Spirit and of power, 5 that your faith wouldn’t stand in the wisdom of men, but in the power of God.
(WEB)
Paul makes a similar point here, saying his preaching came with a demonstration of the Spirit and of power, so that faith would rest on God’s power rather than human wisdom. It shows the same pattern of crediting God for the effectiveness of the message.
Acts 1:8
But you will receive power when the Holy Spirit has come upon you. You will be witnesses to me in Jerusalem, in all Judea and Samaria, and to the uttermost parts of the earth.”
(WEB)
Jesus promises that the Spirit will empower his witnesses to carry the message from Jerusalem outward to the ends of the earth. Romans 15:19 reflects that same geographic and spiritual pattern in Paul’s own mission.
A Short Prayer From Romans 15:19
Lord, you are the one who gives power to the message of Christ. When I feel that my words are small or my efforts are unseen, remind me that your Spirit is able to work beyond what I can measure. Help me to be faithful in speaking of Jesus, to trust you with the results, and to rest in the fact that the good news belongs to you. Amen.
