Here is a short review by Dr. William W. Klein,
What do we consult when we need an introduction to a New Testament book? Typically, we may resort to one of several sources. We could get a very brief synopsis in a study Bible or consult the short entry in a one-volume commentary on the New Testament (or Bible). Of course, there is the distinct genre of “New Testament Introduction.” And finally, one could get hold of one of the commentaries on the book in question and read up the initial pages devoted to setting that book in its context. All of these have their places, but they are also subject to the limitations of space. READ MORE . . . (h.t. Steve Hays).
