(11) All ye Gentiles.--An invitation addressed to the Gentile peoples without restriction, at a time when the monotheistic conception of God as Lord of the whole earth was thoroughly established.

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.And again,.... It is written in Psalm 117:1,

praise the Lord all ye Gentiles, and laud him all ye people; that is, praise him both Jews and Gentiles, for his merciful kindness and truth, as in Romans 15:2; the Gentiles for his mercy in choosing, redeeming, and calling them, as before; and the Jews for his truth and faithfulness in the fulfilment of his praises. R. David Kimchi on this psalm observes, that

"it consists of two verses only, and that it belongs , "to the days of the Messiah"; and intimates, by the composition of it in two verses only, that all people shall be divided into two parts, or be on two sides, Israel shall be in their law, and all the nations in seven precepts,''

i.e. of Noah.
