What are the best books about Mark?
Good books about Mark are not plentiful. WIlliam Lane’s Commentary in the NICNT is still a standard. I recommend Rhodes & Michie’s book Mark as Story. The NAC by Brooks is good and, of course, WIlliam Barclay’s Daily Bible Study Volume is still excellent. The Harper One-Volume Commentary and the IVP Bible Background Commentary are both very good. I especially like The Gospel of Mark by Eduard Schweizer.
