A microscopic pathogen. A YouTube video. A revolutionary idea. When something goes “viral,” it spreads contagiously, circulating the globe, bouncing from person to person, taking on a life of its own. Growing from 1 to 33.8 million followers in a little over three hundred years, the revolutionary message of Jesus went viral. In this series, we explore this virality through the life of Paul, a significant agent in the spread of Jesus’ message as he multiplied leaders, established churches, and kicked off church-planting movements that would spread to a global scale.
