In a word, don’t be a bottom feeder. Bird-dog the footnotes! Chase them down! Don’t rely exclusively on the work of others to familiarize you with the great theological works. Dive in, read, mark, learn, and encourage others to do the same. Start a book club where you read great theological classics, like Augustine’s Confessions or Luther’s Bondage of the Will. And if you’re a pastor, focus on reading deep. Rather than read the latest book by Tim Keller, peruse the footnotes and find out what Tim Keller is reading, pick it up, and read it!
