14 Now I myself am confident concerning you, my brethren, that you also are full of goodness, filled with all knowledge, able also to admonish one another. 15 Nevertheless, brethren, I have written more boldly to you on some points, as reminding you, because of the grace given to me by God, 16 that I might be a minister of Jesus Christ to the Gentiles, ministering the gospel of God, that the offering of the Gentiles might be acceptable, sanctified by the Holy Spirit.
17 Therefore I have reason to glory in Christ Jesus in the things which pertain to God. 18 For I will not dare to speak of any of those things which Christ has not accomplished through me, in word and deed, to make the Gentiles obedient-- 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. 20 And so I have made it my aim to preach the gospel, not where Christ was named, lest I should build on another man's foundation, 21 but as it is written: "To whom He was not announced, they shall see; And those who have not heard shall understand."
Matthew Henry's Commentary on Romans 15:14-21
Commentary on Romans 15:14-21
(Read Romans 15:14-21)
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.
