There are those that think that I do not read deep. This is partially true, but not entirely as I do read some books that are deep. For an evangelism book I would say the book Tell The Truth is deep, and it is also used in many seminaries. I would not say that Puritan books are light as I am trying to get through Bunyan's book on Hell. I also read a little of a book called Ultimate Proof of Creation but was confused, so I will need to read slowly and perhaps more than once. I also have read this book called The Way of the Modern World once and found it very deep, but also very philosophical. Probably a book only a few can understand. Some here read books by DA Carson and NT Wright and they can be quite deep authors. I do not read NT Wright for obvious reasons, but Carson I would like to read, just have not gotten to him yet. I guess we are all at different levels in our readings. Like reading the gospels in the NT are easy compared to OT books like Ezekiel. How often do you hear in depth sermons, or read in depth commentaries on Ezekiel? Rarely.
