E.M. Bounds emphasizes the profound necessity of divine sufficiency in preaching, illustrating that true ministry is empowered by God and the Holy Spirit. He warns against the dangers of non-spiritual preaching, which may appear eloquent but lacks the life-giving energy of the Spirit. Bounds highlights that a preacher must experience a deep surrender to God, recognizing their own powerlessness to effectively convey God's message. The essence of life-giving preaching is rooted in the preacher's inner transformation and crucifixion of self, allowing God's power to flow through them. Ultimately, Bounds calls for a ministry that is not only knowledgeable but also spiritually vibrant and alive.
