14 But I am persuaded, my brethren, I myself also, concerning you, that yourselves also are full of goodness, filled with all knowledge, able also to admonish one another. 15 But I have written to you the more boldly, [brethren,] in part, as putting you in mind, because of the grace given to me by God, 16 for me to be minister of Christ Jesus to the nations, carrying on as a sacrificial service the [message of] glad tidings of God, in order that the offering up of the nations might be acceptable, sanctified by [the] Holy Spirit.
17 I have therefore [whereof to] boast in Christ Jesus in the things which pertain to God. 18 For I will not dare to speak anything of the things which Christ has not wrought by me, for [the] obedience of [the] nations, by word and deed, 19 in [the] power of signs and wonders, in [the] power of [the] Spirit of God; so that I, from Jerusalem, and in a circuit round to Illyricum, have fully preached the glad tidings of the Christ; 20 and so aiming to announce the glad tidings, not where Christ has been named, that I might not build upon another's foundation; 21 but according as it is written, To whom there was nothing told concerning him, they shall see; and they that 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.
