This commentary on Philippians is accessible for anyone who, like me, has not studied the Bible formally in university. The author sometimes draws out the origin of a word to clarify the meaning of a passage but does not linger too long on all the ins and outs of how a word could/should/would be translated.
The book's chapters are short, which made it easy for me to cover one or two of them during my quiet time. There are also Study Questions in the back of the book that one could answer on their own, in a journal, or as part of a Bible Study Group.
