14 And I myself also am persuaded of you, my brethren, that ye yourselves are full of goodness, filled with all knowledge, able also to admonish one another. 15 But I write the more boldly unto you in some measure, as putting you again in remembrance, because of the grace that was given me of God, 16 that I should be a minister of Christ Jesus unto the Gentiles, ministering the gospel of God, that the offering up of the Gentiles might be made acceptable, being sanctified by the Holy Spirit.
17 I have therefore my glorifying in Christ Jesus in things pertaining to God. 18 For I will not dare to speak of any things save those which Christ wrought through me, for the obedience of the Gentiles, by word and deed, 19 in the power of signs and wonders, in the power of the Holy Spirit; so that from Jerusalem, and round about even unto Illyricum, I have fully preached the gospel of Christ; 20 yea, making it my aim so to preach the gospel, not where Christ was [already] named, that I might not build upon another man's foundation; 21 but, as it is written, They shall see, to whom no tidings of him came, And they 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.
