In ancient times, people thought the heavens were not far above the earth. If only they could build a tower to the sky, they could climb up and be like gods themselves. Mankind had once again lost sight of God and become arrogant and self-sufficient.
God, of course, saw this as pure arrogance. He put an end to the people's delusions of being powerful and important like gods.
We may be tempted to think we no longer need to trust and obey God. We may believe our learning, sophistication and technology are all we need to be self-sufficient and guarantee our security. The lesson of the Tower of Babel is that such self-sufficiency is a delusion. History has shown that many nations and their leaders have fallen into the trap of arrogance and self sufficiency. Like Babel, those nations have eventually ended up in ruins.
