"Even if one is committed to some form of systematic preaching from Scripture, choices must be made about each book, and within each book about each segment. This itself involves answering the question central to the preaching itself: How best can I bring God's Word and these people together? THe contents and balance of Scripture will need to be related to the situation and needs of a given congregation."
