I sometimes think the biggest problem today is that we have is that we insist on repeating the error of the builders of the Tower of Babel.
Not because we build tall buildings that none of us can leap in a single bound, but because we share their faith in the powers of our own minds.
The Babylonians' big sin was that of pride, the notion that they were approaching God in their understanding. We (modern "enlightened and educated" man, that is) have repeated that error in spades. Because of the amazing progress we have made in the last 3 centuries or so (technologically, philosophically, scientifically, politically, economically), we deify our own powers of reason and knowledge. And we forget that, even now, what we know about life, the universe, and everything is trivially small compared to what we don't know. We reduce God to "religion" (nothing more than a word for a particular subset of that limited understanding human beings have), rather than remembering that what He is, what He is capable of, dwarfs our limited understanding by orders of magnitude more than our understanding dwarfs that of a Neolithic amoeba.
Babylon's hubris was a belief that matters of importance were explained by solutions to intellectual problems of civil engineering. Ours is more profound, believing that matters of importance are explained by solutions to intellectual problems of civic engineering.
As usual, few of us see even as clearly as Paul did (Romans 12:2; 1 Corinthians 13:12; Philippians 4:7).
And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
Romans 12:2 (NKJV)
