Unity. Unity of language. Unity of speech. Unity of mind.
Imagine if the whole world had only one language. Imagine if everyone spoke the same thing. Imagine if everyone understood everybody else. Mankind would have made it to the moon 4,000 years ago!
It is fathomable to imagine a one world language. For instance, if everyone spoke English there would be more understanding, more sharing of ideas, more sharing of theories, more sharing of inventions. Our world's knowledge base would exponentially increase.
On the other hand, it is unfathomable to imagine a world of "one speech" where everyone says the same thing. Ideas would be the same, reasoning would be the same, beliefs would be the same. People speak the same thing when people are thinking the same thing. The Bible says that our thoughts do not reflect God's thoughts. A world of "one speech" would be united against God.
God wants us to be united with him. After the flood in Noah's day, the world was turning away from God just as it was doing before the flood. There was one language, one speech, and one mindset - against our Creator. This is why God confounded mankind's language in Genesis 11. God will put roadblocks in our path when we are bent on going the wrong way.
When we are confused, do we seek to understand our circumstances in light of God's Word?
