Eternal Life

It is entirely appropriate that a book dealing with the subject of Christian assurance should end with three final affirmations, introduced by the repetitive phrase “we know” in verses 18, 19 and 20. In some ways these statements are a summary of much of what John has been teaching. In another sense they are a reminder of how important affirmations are to Christianity.

John’s first affirmation is that the one who is truly born of God does not sin. At first glance this statement seems to be contradictory to John’s repeated declaration in chapter one that anyone who says that he does not sin or has never sinned is either self-deceived or a liar, just as the section in chapter 3, verses 4-10, seemed to be contradictory to those same statements. But the contradiction is only an apparent one, and our discussion of the earlier passage indicates how we should deal with this.

The second of John’s affirmations is that “we are of God,” joining himself to his readers in this certainty. But where does the certainty come from? In the first instance the certainty that the one born of God does not sin comes from the ability of Jesus (or God) to keep the Christian. In this case the certainty that “we are of God” comes from the fact that the tests of righteousness, love, and sound doctrine have been applied and the results discovered to be positive.
