I have known David Hegg for some time and consider him a faithful servant of Christ, solid pastor, and insightful and knowledgeable expositor of Scripture. This small book arose from a number of years discipling people. It is clear that this work, focused mainly on Ephesians, is meant to be practiced and applied. David writes lucidly and personally showing himself to be a people-person and not merely a theorist. The subject matter is very large (sanctification) and Hegg chooses to limit himself to certain texts. This is both helpful and unhelpful. It is helpful in keeping this book short and sweet and effectively making his point. It is unhelpful because of some key Scriptures that could illumine the subject greatly.
For example, when dealing with the option of obeying God in the midst of temptation, much could be gleaned from James 1 and Galatians 5 on our sin nature and the process of temptation. These passages were not given much time. Anyway, Hegg starts by walking the reader through the gospel and regeneration of soul before moving into training oneself to say yes to righteousness. Hegg offers an excellent summary of the delicate balance between personal diligence and resting in the Holy Spirit. His definition of this combined effort is wonderful. He presents good summaries in chapters 7 and 9 so that the text does not become too technical or the reader confused. His personal examples are helpful.
Dave emphasizes positive reinforcement in his definition of faith. He is obviously motivated by promises of reward over consequences of disobedience. I think both need equal attention. Throughout Scripture, God holds out a carrot while carrying a big stick. We move towards obedience because we want the reward, but that is not enough. We must have fear of God as well. Sometimes, a reward can be downsized in my mind and my motivation may become lessened. It is then that negative reinforcement is required. I want to both avoid bad and obtain good. Dave does present this a little when covering 1 Timothy 2, but he prefers to focus on positive reinforcement. Having said this,it does not detract from a solid work that obviously has been tested local church ministry. That's why I recommend it.
