And the LORD said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. Come, let us go down and there confuse their language, so that they may not understand one another’s speech.”
(Genesis 11:6-7 ESV)
Pastor John Piper has an interesting observation on the diversity of language and world evangelization, from a sermon, “The Pride of Babel and the Praise of Christ:
God’s division of the world into different languages hinders the rise of a global, monolithic anti-Christian state that would have the power to simply wipe out all Christians. 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.
