A readable, non-technical, concise commentary on Mark. For our church's preaching series on Mark, the preachers have referred to this (alongside the more technical commentaries) and all the small group Bible study leaders have used this week by week to aid their preparation -- it's ideal for this purpose. Paul Barnett has written various academic commentaries in other series, so he is well qualified. I'm impressed by the way be distills thorough knowledge of the text into a very readable form, without missing too much of importance. He moves through the passages with an overview style, pausing to comment on significant issues. The questions at the end of each chapters are helpful for small group study, although probably not practical enough to be used on their own. A great balance of accessibility and thoroughness.
