14 I myself am convinced, my brothers and sisters, that you yourselves are full of goodness, filled with knowledge and competent to instruct one another. 15 Yet I have written you quite boldly on some points to remind you of them again, because of the grace God gave me 16 to be a minister of Christ Jesus to the Gentiles. He gave me the priestly duty of proclaiming the gospel of God, so that the Gentiles might become an offering acceptable to God, sanctified by the Holy Spirit.

17 Therefore I glory in Christ Jesus in my service to God. 18 I will not venture to speak of anything except what Christ has accomplished through me in leading the Gentiles to obey God by what I have said and done- 19 by the power of signs and wonders, through the power of the Spirit of God. So from Jerusalem all the way around to Illyricum, I have fully proclaimed the gospel of Christ. 20 It has always been my ambition to preach the gospel where Christ was not known, so that I would not be building on someone else's foundation. 21 Rather, as it is written: "Those who were not told about him will see, and those who have not heard will understand."[1]

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.
