Philip Towner's study of 1 and 2 Timothy and Titus are part of the IVP New Testament Commentary Series, a series which combines pastoral concerns with attention to tough exegetical issues and emphasizes the significance of the biblical text for today's church.
Towner does a great job of saying much in few words in this shorter and simpler presentation of his more extensive commentary. Pastors and teachers who want a simple but informative overview will find this to be a helpful read to complement their own deeper study.
