8 Now I say that Christ has been made a servant of the circumcision to give effect to the undertakings given by God to the fathers, 9 And so that the Gentiles might give glory to God for his mercy; as it is said, For this reason I will give praise to you among the Gentiles, and I will make a song to your name. 10 And again he says, Take part, you Gentiles, in the joy of his people. 11 And again, Give praise to the Lord, all you Gentiles; and let all the nations give praise to him. 12 And again Isaiah says, There will be the root of Jesse, and he who comes to be the ruler over the Gentiles; in him will the Gentiles put their hope.
13 Now may the God of hope make you full of joy and peace through faith, so that all hope may be yours in the power of the Holy Spirit.

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.
