A fellow pastor recently asked me what I was preaching. After I told him that I was preaching through the whole book of Isaiah, he laughed. “Whoa! Good for you! I could never do that!”

I imagine my brother isn’t alone. Preaching through longer books of the Bible does seem like an impossible task for busy pastors. But contrary to what this brother’s response implied, a commitment to preaching through the Bible’s longest books isn’t only for über-pastors, if such a humorous fiction actually existed. Instead, it arises from a simple conviction that every pastor should share: Faithful expository preaching aims to declare the whole counsel of God (Acts 20:27), which includes preaching through the longest books in the Bible.
