For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. Romans 10:12
No matter who we are, we belong to a people tribe of some description. Of course this was not always the case in human history. After God judged the world with a worldwide flood, Noah’s descendants all spoke the same language (Gen. 11:1). But because of sinful hearts, men chose to rebel against God at Babel and God judged mankind again by confusing their language. As a result man scattered over the face of the earth shifting into their different ‘tribes,’ according to their respective languages. (Gen. 11:8-9)
Ever since, the ‘tribes’ of the earth have generally been at odds with one another. All our wars, conflicts, racial hatred, and discrimination are rooted in tribal history and can be traced all the way back to God’s curse on sinful man at Babel.
But - praise God there is one ‘tribe’ where all prejudices and tribal discriminations have been eradicated. All barriers have been removed so these people can come before God as one. This ‘tribe’ are those who have been saved by God’s grace through faith in Jesus Christ. I love how Philip Graham Ryken in his book, Is Jesus the Only Way? Puts this - The family of God is ethnically and culturally diverse. As Christians we not only permit such diversity, but we cherish it. This is because God Himself cherishes ethnic diversity. He is not color-blind; He is colorful. At His throne God welcomes worshipers “from every nation, tribe, people and language” (Rev. 7:9). His plan of redemption is for the peoples of the world in all their rich variety.
