Presenting expository sermons book by book: 1. Allows God and God’s wisdom to set the agenda, not the preacher’s wisdom. 2. Prevents preachers from indulging their hobbyhorses. 3. Allows the preacher to learn along with the congregation, rather than limiting the congregation to what the preacher already knows. 4. Requires a preacher and a congregation to learn about God as God has revealed Himself, not as they want Him to be revealed. 5. Requires a preacher to preach the easy bits and the difficult bits of the Bible.
