In this first message of Winning the Invisible War, Dr. Michael Youssef boldly exposes the satanic deception infiltrating the Church. Drawing from Acts 20, he warns of “fierce wolves” rising from within—twisting Truth and leading many astray. With urgent clarity, Dr. Youssef reminds us that the devil’s lies are not new—they are the same falsehoods used in the Garden of Eden, now dressed in modern disguise. The believer’s call is not only to repent and surrender to the Lordship of Jesus Christ but to guard the doors of the soul from demonic entry—anger, fear, lust, pride. This message is a clear trumpet blast for believers to awaken, intercede, and stand firm in Christ’s power through His Word.
