Trace the development of true freedom of conscience through Roger Williams and the founding principles of the United States. Witness the spiritual decline and formalism that crept into American churches, causing them to neglect the doctrine of the Second Advent. See how God, in His mercy, raised up humble individuals like William Miller, Joseph Bates, and others—empowered by earnest Bible study using the day-year principle—to proclaim the Three Angels’ Messages and arouse a sleeping world to Christ’s imminent return, fulfilling the signs foretold in Matthew 24.
