I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you have overcome the evil one. I write to you, little children, because you know the Father.

 Let us first set out the problem. It is clear that Christianity is an ethical religion; that is what John is concerned to stress. But it is also clear that man is so often an ethical failure. Confronted with the demands of God, he admits them and accepts them--and then fails to keep them. Here, then, there is a barrier erected between man and God. How can man, the sinner, ever enter into the presence of God, the all-holy? That problem is solved in Jesus Christ. And in this passage John uses two great words about Jesus Christ which we must study, not simply to acquire intellectual knowledge but to understand and so to enter into the benefits of Christ.
