Mike Bickle introduces the primary principle of the Harp and Bowl model, emphasizing the importance of developing a biblical passage through antiphonal praying and singing. He explains that this model allows for diverse musical styles while fostering team ministry, inclusiveness, and a focus on Scripture. The worship cycle consists of four stages: corporate worship songs, spontaneous singing, developing a passage through antiphonal praying, and optional warring in the Spirit. Bickle encourages worship leaders to maintain a dominant melody line to facilitate participation and unity among congregants. Ultimately, this model aims to create a dynamic and engaging worship experience that deepens the congregation's connection with God.
