We often think that the diversity of languages and cultures and peoples and political states is a hindrance to world evangelization—the spread of Christ’s glory. That’s not the way God sees it. God is more concerned about the dangers of human uniformity than he is about human diversity. We humans are far too evil to be allowed to unite in one language or one government. The gospel of the glory of Christ spreads better and flourishes more because of 6,500 languages, not just in spite of it.
A great part of the glory of the gospel is that it is not provincial. It is not a tribal religion. It breaks into every language and every people. If there were no diversity of languages, if the spectacular sin of Babel had not happened with its judgment, the global glory of the gospel of Christ would not shine as beautifully as it does in the prism of thousands of languages.
And finally, the praise that Jesus receives from all the languages is more beautiful, because of its diversity, than it would have been if there were only one language and one people to sing. “And they sang a new song, saying, ‘Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth” (Revelation 5:9-10). “After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, and crying out with a loud voice, “Salvation belongs to our God who sits on the throne, and to the Lamb!” (Revelation 7:9-10).
It was the spectacular sin on the plains of Shinar that gave rise to the multiplying of languages that ends in the most glorious praise to Christ from every language on earth. Praise the Lord, O Bethlehem, let everything that has breath praise the Lord.
