T. Austin-Sparks emphasizes the ministries of Elijah and John the Baptist as vital instruments during times of spiritual transition, highlighting their roles as way-makers for the Lord. Both figures experienced profound highs and lows in their spiritual journeys, illustrating the fluctuating nature of human emotions and the necessity of relying on God rather than personal feelings. Sparks points out that God prepares His servants in secret, equipping them to fulfill His greater purposes, and that true ministry requires selflessness and a focus on God's work rather than personal struggles. The sermon encourages believers to recognize their dependence on God and to remain steadfast in their calling, even amidst trials. Ultimately, the message is a call to prioritize the Lord's interests over self-interest, as exemplified by the lives of Elijah and John.
