14 I myself feel confident about you, my brothers and sisters, that you yourselves are full of goodness, filled with all knowledge, and able to instruct one another. 15 Nevertheless on some points I have written to you rather boldly by way of reminder, because of the grace given me by God 16 to be a minister of Christ Jesus to the Gentiles in the priestly service of the gospel of God, so that the offering of the Gentiles may be acceptable, sanctified by the Holy Spirit.
17 In Christ Jesus, then, I have reason to boast of my work for God. 18 For I will not venture to speak of anything except what Christ has accomplished 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 Spirit of God, so that from Jerusalem and as far around as Illyricum I have fully proclaimed the good news of Christ. 20 Thus I make it my ambition to proclaim the good news, not where Christ has already been named, so that I do not build on someone else's foundation, 21 but as it is written, "Those who have never been told of him shall see, and those who have never heard of him 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.
