The resolution of independence!
John Adams, a signer of the Declaration of Independence wrote to his wife Abigail:
The second day of July, 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations, from one end of this continent to the other, from this time forward forever more.
Freedom, independence, liberty is all about no control by government or any other entity and the chance to practice our own rights and powers. Freedom gives us the power to exercise our rights, desires, or the like. Independence is not only lack of restrictions but also the ability to stand alone, not propped up by anyone or anything else, such as government or unwanted laws. Independence allows us to think alone giving all of us new ideas, discoveries, and inventions. Liberty, allows us to govern ourselves.
John Adams prediction was off by two days. From the outset, Americans celebrated independence on July 4, the date shown on the Declaration of Independence, rather than on July 2, the date the resolution of independence was approved in a closed session of Congress.
John Adams died 50 years later on the same day: July 4, 1826
