Everyone who has this hope set on him purifies himself, even as he is pure.

 (i) John thinks in Jewish categories because he could do no other. We have already seen that he knew and accepted the Jewish picture of the two ages, this present age and the age to come. We have also seen that it was John's belief that, whatever the world was like, Christians by virtue of the work of Christ had already entered into the new age. It was exactly one of the characteristics of the new age that those who lived in it would be free from sin. In Enoch we read: "Then too will wisdom be bestowed on the elect, and they will all live and never again sin, either through heedlessness or through pride" (Enoch 5: 8). If that is true of the new age, it ought to be true of Christians who are living in it. But, in fact, it is still not true because Christians have not even yet escaped from the power of sin. We might then say that in this passage John is setting down the ideal of what should be and in the other two passages he is facing the actuality of what is. We might put it that he knows the ideal and confronts men with it; but also faces the facts and sees the cure in Christ for them.
