Actually, if I'm not mistaken, the first signatures were placed on July 2, and the congressional record shows that nothing of any significance took place on the 4th. I don't know why we celebrate the 4th, and I think many historians have asked the same question. I will add that both John Adams, and Thomas Jefferson both died on July 4, 1826. Exactly 50 years after July 4, 1776.
Many don't realize how little credit John Adams received for his part in the revolution, but he was probably the biggest "force" behind the Declairation of Independance. He told John Quincy, "Above all else endeavor to be a good man, and a useful citizen." "Let frugality and industry be our virtues."
I realize that the commandments, "Love God", and "Love thy Neighbor" are encompassed in those quotes. Those quotes are such sound advice. They stretch across time, and are more applicable today than ever. May the Grace of the One and Only True and Living God be shed upon this nation, and those who inhabit it.
My life, my fortune, and my Sacred Honour,
