Accept one another, then just as Christ accepted you, in order to bring praise to God. For I tell you that Christ has become a servant of the Jews on behalf of God's truth, to confirm the promises made to the patriarchs so that the Gentiles may glorify God for his mercy, as it is written:
"Therefore I will praise you among the Gentiles; I will sing hymns to your name."
Again, it says, "Rejoice O Gentiles with his people. And again, "Praise the Lord, all you Gentiles and sing praises to him, all you peoples." An again, Isaiah says, "The Root of Jesse will spring up, one who will arise to rule over the nations; the Gentiles will hope in him."
May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit. (Romans 15:7-13 NIV)
