"And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do." (Genesis 11:6, emphasis mine)

This is God speaking amongst Himself at the Tower of Babel. It's one of those passages in the Old Testament that speaks to the Trinity (in my opinion) before the Trinity was clearly and succinctly defined. The next verse says "Go to, let us go down...". And so they intervened. When we read the story of the Tower of Babel, we tend to see it a story of a Divine Intervention along the lines of confusion and misunderstanding. When Paul says in his first letter to the Corinthians (14:33) that "God is not the author of confusion, but of peace", he qualifies it with "in all churches". Granted, this is the New Testament, the New Covenant between God and humanity through Christ's sacrifice. But at Babel? It would seem the inherent confusion came, not from God's "confounding" their language, but of the Babel-onians (?) seeking to obtain re-entry to Heaven through means other than ordained.

Coming and going as we please…

"Now nothing will be restrained from them..." As in "held back"? As in "hidden"? I shudder. God is watching and speaking. We as a race are well on our way to unraveling the mysteries of God's universe. It would seem nothing is restrained from us. As an aside, there are over six-thousand languages the world over. How much more confusion and misunderstanding can we as a race bring upon ourselves? Not because of language, but because of pride? Food for thought.

"And the Lord said, Shall I hide from Abraham that thing which I do." (Genesis 18:17)

God knows

A rhetorical, if exasperated expression. In spite of the complexity of our brains and minds, we know relatively little. And it's not that God is unwilling to show us anything. It's a matter of humility and of timing and of calling. We also tend to do something called forget. And so we trust. Because "knowledge shall vanish away", (1 Corinthians 13:8) trust and love are the order of the day. Abraham was called by God to start something huge. And so God could be open and honest with him. I would wager that we're all called to do something earth-shakingly huge for God. As everyone is a piece of Him, having been created by Him, the desires of our heart are limited only by the sky—i.e. our imagination (read: faith). God will show you what you need to know.
