Clearly the "date" is not important but the act. John Adams referring to the day the Congress passed Richard Henry Lee's resolution for independence rather than the one on which Congress adopted the declaration wrote to his wife Abigail on 3 July, 1776:
"The second day of July, 1776, will be the most memorable epocha 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 for evermore."

In 1837 John Adams' son, President John Quincy Adams, our sixth president, tells us why the 4th was regarded a religious holiday in a speech he gave on July 4, during the 61st anniversary of the signing of the Declaration of Independence:
"Why is it that, next to the birthday of the Savior of the World, your most joyous and most venerated festival returns on this day? Is it not that ….the birthday of the nation is indissolubly linked with the birthday of the Savior?… Is it not that the Declaration of Independence first organized the social compact on the foundation of the Redeemer's mission upon earth?
That it laid the cornerstone of human government upon the first precepts of Christianity and gave to the world the first irrevocable pledge of the fulfillment of the prophecies announced directly from heaven at the birth of the Savior and predicted by the greatest of the Hebrew prophets 600 years before" (Isaiah 9:6,7).
On another July 4th religious celebration in 1821, John Quincy Adams told his audience that "The highest glory of the American Revolution was this; it connected in one indissoluble bond the principles of civil government with the principles of Christianity."

Celebrating the day America became free and independent states
6/30/2006 - MCCONNELL AIR FORCE BASE, Kan. (AFPN) --
"The second day of July 1776, will be the most memorable epocha in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival.
"You will think me transported with enthusiasm but I am not. I am well aware of the toil and blood and treasure, that it will cost us to maintain this declaration, and support and defend these states. Yet through all the gloom I can see the rays of ravishing light and glory. I can see that the end is more than worth all the means."
When John Adams penned these words to his wife, Abigail, on July 3, 1776, he did not realize that the "succeeding generations" of his fellow citizens would actually celebrate July 4 as the day of national independence. He was sure they would remember the day the Congress passed Richard Henry Lee's resolution for independence rather than the one on which Congress adopted the declaration.

The scroll of the prophet Isaiah was handed to him. Unrolling it, he found the place where it is written:
"The Spirit of the Lord is on me, because he has anointed me to preach good news to the poor. He has sent me to proclaim freedom for the prisoners and recovery of sight for the blind, to release the oppressed, to proclaim the year of the Lord's favor."
Then he rolled up the scroll, gave it back to the attendant and sat down. The eyes of everyone in the synagogue were fastened on him, and he began by saying to them, "Today this scripture is fulfilled in your hearing." Luke 4:17-21
...whenever anyone turns to the Lord, the veil is taken away. Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 2 Corinthians 3:16-17
Do not merely listen to the word, and so deceive yourselves. Do what it says. Anyone who listens to the word but does not do what it says is like a man who looks at his face in a mirror and, after looking at himself, goes away and immediately forgets what he looks like. But the man who looks intently into the perfect law that gives freedom, and continues to do this, not forgetting what he has heard, but doing it--he will be blessed in what he does. James 1:22-25
In him and through faith in him we may approach God with freedom and confidence. Ephesians 3:12
