In this final message of Spirituality That Heals, Dr. Michael Youssef delivers a powerful warning: without Holy Spirit–filled self-control, believers are as defenseless as a city without walls. Preaching from Galatians 5, Proverbs, and 1 Corinthians 9, he exposes the lies of self-mastery and self-improvement, declaring that true self-control is not willpower—it is Spirit power. Our flesh craves indulgence, but the Spirit demands surrender. Dr. Youssef urges believers to reject compromise, repent of passivity, and fix their focus on the eternal crown that awaits the faithful. Only through daily surrender and deep gratitude for Christ’s finished work can the Church stand strong, resist temptation, and glorify God in every area of life.
