8 Now I say that Jesus Christ has become a servant to the circumcision for the truth of God, to confirm the promises made to the fathers, 9 and that the Gentiles might glorify God for His mercy, as it is written: "For this reason I will confess to You among the Gentiles, And sing to Your name." 10 And again he says: "Rejoice, O Gentiles, with His people!" 11 And again: "Praise the Lord, all you Gentiles! Laud Him, all you peoples!" 12 And again, Isaiah says: "There shall be a root of Jesse; And He who shall rise to reign over the Gentiles, In Him the Gentiles shall hope."
13 Now may the God of hope fill you with all joy and peace in believing, that you may abound in hope by the power of the Holy Spirit.
Matthew Henry's Commentary on Romans 15:8-13
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.
