Life in Christ: Studies in 1 John
Martyn Lloyd-Jones
Crossway
In his book Life in Christ, Martyn Lloyd-Jones says that the theme of 1 John is fellowship with God. Fellowship is most possible when Christians have an assurance of salvation: “There is nothing as vitally important as our certain knowledge that God has loved us in particular in Christ…”
How can Christians have assurance? How can they know that they are living a “life in Christ?” There are certain tests that John repeats throughout his epistle. These tests are the topics most dealt with by Lloyd-Jones in this book.
First, do we love God? If so, our love will show itself in a practical way: we will keep His commandments. “Love is not a sentiment; it is the most active, vital thing in the world. If I love, I want to please—I keep the commandments; and what I may regard as the love of God in my soul is a pure delusion unless it leads me to keep God’s commandments and to live life as He wants me to live it.”
Next, we must love our Christian brothers and sisters. This is the ultimate proof that we love God. Again, this love is not to be based upon feelings, nor is it to be based upon whether a particular person is lovable or not. Our love should proceed from our new nature, as God’s love proceeds from His nature. “We must once and for ever get rid of the idea that God has loved us by way of response either to something that is in us or to something we have done,” and so we should love others regardless of how they act or treat us. “That is what salvation is for, to enable us to love God and to love our neighbor as ourselves.” What is the nature of this love toward the brethren? “It acts, it gives, it expresses itself.”
Dr. Lloyd-Jones begins each chapter with an explanation of the theology behind John’s passage: “We must start always by realizing the doctrine; always start with truth.” After the theology has been dealt with, he moves on to the practical application, giving the reader such things as “Ten tests which you can apply to yourself to know for certain that you know the love of God.”
Life in Christ was originally published in five volumes: Fellowship with God, Walking with God, Children of God, the Love of God, and Life in God. Each of these volumes corresponded to a chapter in 1 John, and they are now the main sections of this one-volume, 734 page book published by Crossway.
If you are looking for a book that will make you feel good about yourself, this is not the one. The Doctor is concerned to give true believers reasons for assurance, but he is equally concerned to strip non-believers of false assurance. If you prefer “easy believism,” you will not enjoy this book. If, however, you want to honestly examine your claim to Christianity in light of the Word of God, I recommend Life in Christ to you.
