T. Austin-Sparks emphasizes that prophetic ministry is an eternal function rooted in God's divine counsel, not merely a role one can adopt. He illustrates this through the symbolism of the Cherubim and the life of Moses, highlighting that true prophets are shaped by their experiences and must undergo a process of self-emptying to embody God's thoughts. Sparks argues that the identity of the prophet is inseparable from their message, and that genuine prophetic ministry arises from a deep, personal relationship with God, rather than academic training. He stresses the importance of humility and the necessity for prophets to be molded by their trials, ultimately becoming living expressions of God's truth. The sermon concludes with the idea that prophetic ministry is a life lived in alignment with God's will, rather than a set of teachings or doctrines.
