John Sung reflects on the profound question of what it profits a man to gain the world yet lose his soul, emphasizing the importance of spiritual truth over worldly achievements. Despite his academic success in the United States, he faced a crisis of faith at Union Theological Seminary, leading to a transformative experience that resulted in his commitment to evangelism. After being institutionalized for his fervent faith, he dedicated his life to preaching the gospel in China, leading hundreds of thousands to Christ through his passionate sermons and hours of prayer. His legacy as a powerful evangelist continues to inspire many, even after his untimely death at the age of 43.
