The phrase "Secure the blessings of liberty to ourselves and our posterity" is found in the Preamble of the United States Constitution. The Preamble serves as an introductory statement and outlines the broad purposes and principles of the Constitution. It expresses the goals of the Constitution, including the establishment of a just and free society that safeguards individual liberties and promotes the welfare of both current and future generations ("our posterity"). While the Preamble does not explicitly delve into the specific structures or functions of the Constitution, it sets the tone and overarching objectives that guide the subsequent articles and provisions of the Constitution.
