This powerful sermon traces the biblical foundation and historical continuity of baptism by immersion, contrasting it with man-made traditions like infant sprinkling. From ancient underground Christian cities in Cappadocia to early church baptistries across Europe and the Middle East, the message is clear: baptism is a personal, public declaration of loyalty to Christ. The speaker challenges modern Christians to return to biblical truth, confront religious traditions, and fully commit to Jesus through baptism.
