How did jefferson use locke's ideas about natural rights and a social contract in the declaration of independence?

Thomas Jefferson ranked Locke, along with Locke’s compatriot Algernon Sidney, as the most important thinkers on liberty. Locke helped inspire Thomas Paine’s radical ideas about revolution. Locke fired up George Mason. From Locke, James Madison drew his most fundamental principles of liberty and government. Locke’s writings were part of Benjamin Franklin’s self-education, and John Adams believed that both girls and boys should learn about Locke. The French philosopher Voltaire called Locke “the man of the greatest wisdom. What he has not seen clearly, I despair of ever seeing.” 

It taught people how to live a good life, but not what to believe.
