David Davis emphasizes the significance of Elijah's hidden life with God, illustrating how the prophet received God's word and obeyed by retreating to the brook Kherit. This period of solitude was crucial for Elijah's spiritual preparation, allowing him to commune with God and receive sustenance, both physically and spiritually. Davis highlights that true ministry begins with a deep, personal relationship with God, where one learns obedience and faithfulness in the small things. The brook symbolizes a place of inheritance and intimacy with God, where believers can be refreshed and prepared for their calling. Ultimately, the sermon calls for a commitment to a private life of prayer and communion with God, which is essential for effective public ministry.
