This commentary is aimed for the young Christian and the group study leader. It is well designed and easy to navigate. It is also reasonably detailed and readable. Generally it gives the various alternative interpretations for difficult texts, including the rapture and millennium. The text of Revelation is in bold, and the comments are on one or two verses at a time, with the fragment of text being commented on highlighted in italics. It alternates between different modern bible versions, which I found annoying. It does a reasonable job of interpreting the meaning of the symbols. It includes additional tables and maps, an index, application notes and classic quotes from noted Christian thinkers.
There are instances of sloppy interpretation or editing, such as saying that the church at Ephesus was filled with pride, which is not what the text says, pride applies more to Laodicea. The mighty angel of 10:1 becomes an archangel by 10:2. On page 173 it misquotes Tertullian by saying, "The blood of the martyrs is seed" it should be "The blood of the martyrs is the seed of the church" (or seedbed of the church). However these are minor criticisms on what is basically a sound commentary.
Its strength is that it avoids the crass sensationalism and fiction of some modern interpretations and in general it follows the interpretation given by the more scholarly commentaries, which is to be welcomed. It is readable and not over technical and will help make Revelation meaningful to the young Christian. It is not so brief as to be useless but it packs quite a lot of information in its 284 pages making it worth buying.
The study leader will find Keener useful for application and Johnson or Krodel useful for further detail, with Mounce as a more scholarly reference. Other useful commentaries for the layman are Hendriksen and Ladd.
