In Lost Its Vision, Dr. Michael Youssef proclaims Christ’s encouraging words to the faithful church in Philadelphia—believers with little strength, yet great faith. Preaching from Revelation 3, Dr. Youssef reveals Jesus’ urgent call to walk through open doors while they remain. These doors are Gospel opportunities, not guaranteed forever. The glorified Christ, holding the keys of David, alone opens and shuts such doors—and His patience with spiritual laziness will soon end. To those who obey, Jesus promises eternal security, divine protection, and a new name written in Heaven. In a world growing hostile to Truth, now is the time to reject fear, stand firm, and proclaim Christ with boldness.
