What is the purpose of the declaration of independence and the declaration of the rights of man documents?

The main purpose of both documents is to assert the rights and freedoms of the people to form their own governments -- governments which will protect their rights as citizens.

Historical context:

The Declaration of Independence (1776) asserted the American colonies' decision to break away from British government.  It included the same Enlightenment ideals of natural rights and liberties that would characterize the Declaration of the Rights of Man and Citizen produced later (1789) in France.

The Declaration of the Rights of Man and the Citizen is a fundamental document of the French Revolution, which was written by Abbé Sieyès and the Marquis de Lafayette.  Abbé Sieyès was a prominent clergyman in France who supported the rights of the common people.  The Marquis de Lafayette was a member of the nobility who had fought in America's war for independence against Britain. Their document was written in consultation with Thomas Jefferson of the United States, who had drafted the Declaration of Independence.

isaiah 53: 4-6 and   romans 5: 6-8 speak how jesus was pierced for our transgressions,   crushed for our iniquities and that god demonstrates his own love for us in this: while we were still sinners, christ died for us, and by his wounds we are all healed.   psalm 22: 6-7 and   matthew 27: 39-40   correlate basically by the fact that all of the people who didn´t believe in jesus, were telling him that if he was so powerful as he said he was, he should save himself.     matthew 27: 35 and psalm 22: 18 refers about how they divided his clothes among them   and cast lots for his garment. isaiah 53: 8-9 and matthew 27: 57-60 express the process of the burial of jesus. psalm 22: 15-16 and luke 23: 33-34 speak about his crucifiction, the humilliation of being surrounded by sinners, and asking the lord for mercy for humanity. finally in john 19: 33-35   and isaiah 53: 12 speak about the most important prophecy, the testimony of a living god, who resurrected and buried all of our sins and guilt, for all of us. when he was crucified a man saw a sudden flow of blood and water from his wound, and he gived testimony, for all o us to believe, that he poured out his life unto death,   and was numbered with the transgressors.   for he bore the sin of many,   and made intercession for the transgressors.
