“Preaching is a theological task. The preacher has the responsibility of taking God's truth and proclaiming that truth to the world. Preachers are schooled in theology and biblical studies. And the best preachers take pride in the time they invest in Bible study and theological thought. They pay attention to the theological nature of the homiletic mandate.”
