Again, I write a new commandment to you, which is true in him and in you; because the darkness is passing away, and the true light already shines.

 The first thing to note in this passage is the sheer affection in it. John begins with the address, "My little children." Both in Latin and in Greek diminutives carry a special affection. They are words which are used, as it were, with a caress. John is a very old man; he must be, in fact, the last survivor of his generation, maybe the last man alive who had walked and talked with Jesus in the days of his flesh. So often age gets out of sympathy with youth and acquires even an impatient irritableness with the new and laxer ways of the younger generation. But not John, in his old age he has nothing but tenderness for those who are his little children in the faith. He is writing to tell them that they must not sin but he does not scold. There is no cutting edge in his voice; he seeks to love them into goodness. In this opening address there is the yearning, affectionate tenderness of a pastor for people whom he has known for long in all their wayward foolishness and still loves.
