Celebrating the Founding of the United States and the US Constitution: This is a great discussion guide that was used in The Church of Jesus Christ of Latter-day Saints as a Sunday School lesson. It includes a video from President D. Todd Christofferson and Elder Quentin L. Cook, two apostles of the Church, talking about the divine establishment of the U.S. Constitution.
The Constitution: A Glorious Standard by Ezra Taft Benson: A 1986 BYU devotional address in which President Benson, then prophet of the Church of Jesus Christ of Latter-day Saints, testified that the United States Constitution was literally inspired by God, established by choice spirits whom the Lord raised up for that specific purpose, and grounded in the eternal principle of agency. He closes with a prophetic charge that Latter-day Saints have a sacred duty to study the Constitution, live righteously, and be among those who will bear it away from the very verge of destruction as Joseph Smith foretold.
