This has been occupying my mind for weeks now so I want to throw it out there and see what y'all think.
Genesis 11:4-9
Then they said, “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves; otherwise we will be scattered over the face of the whole earth.”
But the LORD came down to see the city and the tower the people were building. The LORD said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them. Come, let us go down and confuse their language so they will not understand each other.”
So the LORD scattered them from there over all the earth, and they stopped building the city. That is why it was called Babel—because there the LORD confused the language of the whole world. From there the LORD scattered them over the face of the whole earth.
Since "everything happened to them as examples" (1 Cor 10:11), does anyone else see in this story the hundreds of denominations in existence today? Their confused languages. So they will not understand each other.
Interesting also that "the whole world" was not scattered over the face of the whole earth prior to God making it so.
