Life in Christ is one of the best books by Lloyd-Jones I have read. I am being regularly challenged and convicted as I read.
Here is a section, in the context of commenting on I John 4:7-8:
What does he mean when he exhortss and pleads with us to 'love one another'? I cannot think of a better way of putting it than simply to say that we are to be manifesting in our lives with one another, and in our attitudes toward one another, everything that we read about in I Corinthians 13... There are things that should not belong to us, but they are there, and this calls for patience in others, it calls for sympathy, it calls for understanding; and that is what John is pleading for at this point. He is asking these people to do all they can to help one another, to bear with one another, not to be antagonistic, not to become irritated. If you see your brother at fault, be patient with him, pray for him, try to help him, be sorry for him, instead of feeling it is something that is hurting you. See it as something that is hurting him terribly and doing him great harm and robbing him of so much joy in his Christian life.
