14 I am fully convinced, my dear brothers and sisters, that you are full of goodness. You know these things so well you can teach each other all about them. 15 Even so, I have been bold enough to write about some of these points, knowing that all you need is this reminder. For by God's grace, 16 I am a special messenger from Christ Jesus to you Gentiles. I bring you the Good News so that I might present you as an acceptable offering to God, made holy by the Holy Spirit.
17 So I have reason to be enthusiastic about all Christ Jesus has done through me in my service to God. 18 Yet I dare not boast about anything except what Christ has done through me, bringing the Gentiles to God by my message and by the way I worked among them. 19 They were convinced by the power of miraculous signs and wonders and by the power of God's Spirit. In this way, I have fully presented the Good News of Christ from Jerusalem all the way to Illyricum. 20 My ambition has always been to preach the Good News where the name of Christ has never been heard, rather than where a church has already been started by someone else. 21 I have been following the plan spoken of in the Scriptures, where it says, "Those who have never been told about him will see, and those who have never heard of him will 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.
