E.M. Bounds emphasizes the significance of 'unction' in true gospel preaching, describing it as a divine quality that transcends mere human effort and eloquence. He asserts that unction is what makes preaching powerful and effective, piercing the hearts of listeners and distinguishing true preachers from those who rely solely on earnestness or intellect. Bounds highlights that this unction is a gift from God, cultivated through prayer and spiritual devotion, and is essential for conveying the transformative message of the Gospel. He warns against confusing earnestness with unction, as the former can lack the divine presence that brings true conviction and change. Ultimately, Bounds calls for preachers to seek this heavenly endowment to fulfill their calling effectively.
