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.
English Standard Version
19 by the power of signs and wonders, by the power of the Spirit of God--so that from Jerusalem and all the way around to Illyricum I have fulfilled the ministry of the gospel of Christ;
19 In such ways I have trailblazed a preaching of the Message of Jesus all the way from Jerusalem far into northwestern Greece.
New King James Version
19 in mighty signs and wonders, by the power of the Spirit of God, so that from Jerusalem and round about to Illyricum I have fully preached the gospel of Christ.
New Living Translation
19 They were convinced by the power of miraculous signs and wonders and by the power of God's Spirit. In this way, I have fully presented the Good News of Christ from Jerusalem all the way to Illyricum.
The apostle was persuaded that the Roman Christians were filled with a kind and affectionate spirit, as well as with knowledge. He had written to remind them of their duties and their dangers, because God had appointed him the minister of Christ to the Gentiles. Paul preached to them; but what made them sacrifices to God, was, their sanctification; not his work, but the work of the Holy Ghost: unholy things can never be pleasing to the holy God. The conversion of souls pertains unto God; therefore it is the matter of Paul's glorying, not the things of the flesh. But though a great preacher, he could not make one soul obedient, further than the Spirit of God accompanied his labours. He principally sought the good of those that sat in darkness. Whatever good we do, it is Christ who does it by us.
