Preaching through Books of the Bible

I am an advocate of preaching through books of the Bible believing that the practice benefits both the preacher and the congregation. Orrick, Payne, and Fullerton explain one of the important benefits for the preacher below.

"The first argument for the lectio continua method is that it helps the preacher personally to grow in knowledge and obedience by his disciplined encounter with and immersion in God's Word. Because the under-shepherd cannot lead his flock where he himself is not going, this may be the most fundamental argument for this method, This is not to say that preachers who do not employ the lectio continua method are not immersed in God's Word; but in the proposed method, immersion in the text is virtually inevitable. By definition,you are seeking to come to terms with what the author is saying in the particular text and how it fits with the overall argument of the book, and why it matters. In other words, you are askingand answering the "what?" of the text, the "so what?" of the text, and the "now what?" of the text; and this discipline, week in and week out, brings enormous benefit to the preacher even before it benefits the congregation."
