Good shepherds pray for the help of the Holy Spirit in preparing biblical sermons that provide sufficient food for God’s sheep. Furthermore, they expect the Spirit to work in the hearts of listeners so that they may effectively receive the preached Word. But are these the only ways in which preachers should depend on the Spirit in their preaching? In this book, Albert N. Martin reminds ministers of the gospel that they must depend on the Holy Spirit as they proclaim the Word of God. He explains the necessity of the agency (work) and operations of the Holy Spirit; describes His specific manifestations; and discusses the ways in which His work is restricted or diminished. This is a prophetic call to depend on God in the very act of proclaiming His Word.
