There are hundreds of books on preaching but not very many on listening to preaching. So when I come across one that looks helpful, I want to make others aware of it. Tim Challies has a brief review of Ken Ramey's new book, Expository Listening: A Handbook for Hearing and Doing God's Word, which looks to be one of those. You can read Challies' review here.
Other helpful resources for listening to sermons include Christopher Ash's booklet, Listen Up: A Practical Guide to Listening to Sermons and the first chapter ("A Healthy Church Member Is an Expositional Listener") in Thabiti Anyabwile's little book, What is a Healthy Church Member?. I highly recommend both of these.
