12 and again, Isaiah saith, 'There shall be the root of Jesse, and he who is rising to rule nations—upon him shall nations hope;'
13 and the God of the hope shall fill you with all joy and peace in the believing, for your abounding in the hope in power of the Holy Spirit.
14 And I am persuaded, my brethren—I myself also—concerning you, that ye yourselves also are full of goodness, having been filled with all knowledge, able also one another to admonish;

Commentary on Romans 15:8-13
(Read Romans 15:8-13)
Christ fulfilled the prophecies and promises relating to the Jews, and the Gentile converts could have no excuse for despising them. The Gentiles, being brought into the church, are companions in patience and tribulation. They should praise God. Calling upon all the nations to praise the Lord, shows that they shall have knowledge of him. We shall never seek to Christ till we trust in him. And the whole plan of redemption is suited to reconcile us to one another, as well as to our gracious God, so that an abiding hope of eternal life, through the sanctifying and comforting power of the Holy Spirit, may be attained. Our own power will never reach this; therefore where this hope is, and is abounding, the blessed Spirit must have all the glory. "All joy and peace;" all sorts of true joy and peace, so as to suppress doubts and fears, through the powerful working of the Holy Spirit.
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.
