This is a book that examines how the voice of God speaks to the hearer of the Gospel of Christ, and how hearing that voice is vitally important to understand the Gospel and have the "saving faith" to receive Christ. It is important that the voice we hear is totally consistent with the Bible. Preachers need to pray that as they preach the Word that the voice of the Holy Spirit speaks through them. This makes the difference between people responding positively to the Gospel and merely walking away saying, "That was a good sermon" but doing nothing about it. When the voice of the Holy Spirit speaks through the Word, one must do something - accept it to one's eternal joy, or reject to their destruction. This would gives a good comprehensive rending of the principles for us to know that we can get the voice of God to speak through us as we preach the Word.
