All of us who were engaged in the struggle (for independence) must have observed frequent instances of a superintending providence in our favor. To that kind providence we owe this happy opportunity of consulting in peace on the means of establishing our future national felicity. And have we now forgotten that powerful friend? or do we imagine that we no longer need his assistance? I have lived, Sir, a long time, and the longer I live, the more convincing proofs I see of this truth- that God Governs in the affairs of men. And if a sparrow cannot fall to the ground without his notice, is it probable that an empire can rise without his aid? We have been assured, Sir, in the sacred writings (Bible), that “except the Lord build the House they labour in vain that build it” (c.f. Psalm 127:1). I firmly believe this; and I also believe that without his concurring aid we shall succeed in this political building no better, than the Builders of Babel…
— Franklin’s request for prayers at the Constitutional Convention. July 28, 1787.
Benjamin Franklin was saying if we don’t establish this Constitution on the premise that God is the One who rules over nations then we will do “do no better than the Builders of Babel.”
You ask, “What happened to the builders of Babel (Gen. 11)?”
They became confused, baffled, they could not longer work together. They were divided amongst themselves, dispersed, and their project fell because the Lord acted against these proud people that had set themselves against God.
We need to be reminded of these things two-hundred and twenty-seven years later.
