In the opening message of Healthy Living in a Sick World, Dr. Michael Youssef boldly confronts the spiritual sickness of our modern age—and the dangerous temptation for believers to conform to it. Drawing from 1 Corinthians, Dr. Youssef exposes how the moral decay of ancient Corinth mirrors our own culture today. Yet amid this decay, the Apostle Paul calls even flawed believers “saints,” not because of their performance but because of their position in Christ. Dr. Youssef urges us to live in a manner worthy of our calling: rejecting division, embracing unity in Christ, and submitting wholly to God’s inerrant Word. The Church must resist spiritual infection, stand on Truth, and remember who we are—redeemed and sanctified children of the living God.
