Titus and Philemon by D Edmond Hiebert and published by Classics Publishing.
In this devotional style commentary, these two of the shorter letter from the Apostle Paul, Dr Hiebert has provided an excellent outline of each book, and concise thoughts following the thought of these useful and important Epistles.
The theme of Titus as is all of the Pastoral Epistles, there is the close connection of true, Biblical doctrine and the godliness exemplified in the Christian life. Although somewhat neglect by some readers, this short study gives important lessons, to all Christians regardless of their level of maturity.
In Philemon, which is the smallest of Paul's letter, it is written on behalf of a runaway slave and it is unique among the writings of the Apostle Paul. It through an interesting and valuable light on the social operations of the Gospel, showing Christian brotherhood in action.
