In this urgent message, Be Vigilant, Dr. Michael Youssef calls believers to wake up to the relentless war Satan wages against the children of God. Drawing from 1 Peter 5:8–9, he warns that the devil prowls like a roaring lion, seeking to destroy those who are spiritually drowsy and disobedient. Dr. Youssef exposes how sin dulls our spiritual senses and invites attack, but also proclaims the unbreakable security of those who are truly in Christ. With boldness and clarity, he shows that repentance, obedience, and dependence on the Holy Spirit are the keys to resisting the enemy. This episode aligns with the series’ call to stand firm in Christ’s victory and to live alert in the power of the Gospel.
