John and Christian explore how music shaped the rise of Pentecostal and charismatic movements, tracing its influence from early tent revivals to modern worship concerts. They discuss the psychology of rhythm, the role of instruments like the organ in altering group dynamics, and the way leaders used music to heighten emotional responses during meetings. Drawing on personal stories, historical examples, and biblical references such as Paul’s speech in Athens, they highlight how music can connect or divide people, inspire genuine worship, or be weaponized for manipulation. This conversation reveals that while music is often labeled “holy” or “evil,” it is ultimately a powerful tool that reflects the intention behind its use.
