19 By signs and wonders, in the power of the Holy Spirit; so that from Jerusalem and round about as far as Illyricum I have given all the good news of Christ; 20 Making it my purpose not to take the good news where Christ was named, so that my work might not be resting on that of others; 21 But as it is said in the holy Writings, They will see, to whom the news of him had not been given, and those to whose ears it had not come will have knowledge.
Matthew Henry's Commentary on Romans 15:19-21
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.
