Isaiah 66:18-23 (ESV)
 “For I know their works and their thoughts, and the time is coming to gather all nations and tongues. And they shall come and shall see my glory,  and I will set a sign among them. And from them I will send survivors to the nations, to Tarshish, Pul, and Lud, who draw the bow, to Tubal and Javan, to the coastlands far away, that have not heard my fame or seen my glory. And they shall declare my glory among the nations.  And they shall bring all your brothers from all the nations as an offering to the LORD, on horses and in chariots and in litters and on mules and on dromedaries, to my holy mountain Jerusalem, says the LORD, just as the Israelites bring their grain offering in a clean vessel to the house of the LORD.  And some of them also I will take for priests and for Levites, says the LORD.  “For as the new heavens and the new earth that I make shall remain before me, says the LORD, so shall your offspring and your name remain.  From new moon to new moon, and from Sabbath to Sabbath, all flesh shall come to worship before me, declares the LORD.
Colossians 3:11-14 (ESV)
 Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all.  Put on then, as God’s chosen ones, holy and beloved, compassionate hearts, kindness, humility, meekness, and patience,  bearing with one another and, if one has a complaint against another, forgiving each other; as the Lord has forgiven you, so you also must forgive.  And above all these put on love, which binds everything together in perfect harmony.
