This classic by Horatius Bonar is essential to any true minister of the gospel or serious Christian teacher. It greatly helps clarify the central purpose of the gospel minister in calling men to Christ, and also aids in identifying the numerous problems that can creep into the life of a minister through carelessness and indifference. As Bonar explores many of the problems of his day, we find that we still struggle with the same problems in our day. For the cure to these ills, he reminds us of the successful labors of ministers of the past, and points us to the same great Resource they had.

This little book will assist you in your divine calling, and spur you on to a renewed vigor in the Christian ministry.
