A.W. Tozer emphasizes the necessity of divine authority in preaching, asserting that preachers must embody the authority of God to hold their congregations accountable to the Word. He critiques the lack of moral ascendancy in many pulpits, suggesting that some preachers have been dulled by seminary training, failing to challenge their congregations effectively. Tozer argues that a preacher should reign from the pulpit with the same authority as a king, relying on the Holy Spirit to empower their message. The call is for preachers to deliver the whole counsel of God with conviction, ensuring that their words resonate with divine power.
