It’s great that McMunn starts his book with the Trinity unlike the usual gospel presentation. At first you might think it’s a short book about doctrine, but it’s not. Essentials is an evangelistic book . Essentials is giving a step by step explanation of the gospel. And as I have said McMunn started this book with the Trinity and ends with an invitation to have a relationship with God. Essentials is a presentable evangelistic tool because of appealing title, chapter title and cover image.
There are downsides in book. First, in chapter 3 which illustrates how Jesus rescues. Although the context is answering the question “So why didn’t he save himself? Why did Jesus stay on the cross?” an illustration of a kid drowning is not the biblical way to represent humanity submerged in sin. Total depravity points us that we are not drowning but dead at the bottom of the river. Second the sinner’s prayer at the last part of the book, which is for me unbiblical. Decisionism is not part of the gospel message.
Essentials is a good book but has problematic issues. If for not those issues, I would have graded this book a bit higher. Still you can benefit reading it for yourself and use some parts of it for your personal evangelism.
