1 John 2:3-6

And it is by this that we know that we have come to know him--if we keep his commandments. He who says, "I have come to know him" and who does not keep his commandments is a liar, and the truth is not in such a man. The love of God is truly perfected in any man who keeps his word. This is the way in which we know that we are in him. He who claims that he abides in him ought himself to live the same kind of life as he lived.

This passage deals in phrases and thoughts which were very familiar to the ancient world. It talked much about knowing God and about being in God. It is important that we should see wherein the difference lay between the pagan world in all its greatness and Judaism and Christianity. To know God, to abide in God, to have fellowship with God has always been the quest of the human spirit, for Augustine was right when he said that God had made men for himself and that they were restless until they found their rest in him. We may say that in the ancient world there were three lines of thought in regard to knowing God.

(i) In the great classical age of their thought and literature, in the sixth and fifth centuries before Christ, the Greeks were convinced that they could arrive at God by the sheer process of intellectual reasoning and argument. In The World of the New Testament, T. R. Glover has a chapter on The Greek in which he brilliantly and vividly sketches the character of the Greek mind in its greatest days when the Greek glorified the intellect. "A harder and more precise thinker than Plato it will be difficult to discover, said Marshall Macgregor. Xenophon tells how Socrates had a conversation with a young man. "How do you know that?" asked Socrates. "Do you know it or are you guessing?" The young man had to say, "I am guessing." "Very well, answered Socrates, "when we are done with guessing and when we know, shall we talk about it then?" Guesses were not good enough for the Greek thinker.

To the classical Greek curiosity was not a fault but was the greatest of the virtues, for it was the mother of philosophy. Glover writes of this outlook: "Everything must be examined; all the world is the proper study of man; there is no question which it is wrong for man to ask; nature in the long run must stand and deliver; God too must explain himself, for did he not make man so?" For the Greeks of the great classical age the way to God was by the intellect.

It has to be noted that an intellectual approach to religion is not necessarily ethical at all. If religion is a series of mental problems, if God is the goal at the end of intense mental activity, religion becomes something not very unlike the higher mathematics. It becomes intellectual satisfaction and not moral action; and the plain fact is that many of the great Greek thinkers were not specially good men. Even men so great as Plato and Socrates saw no sin in homosexuality. A man could know God in the intellectual sense but that need not make him a good man.

(ii) The later Greeks, in the immediate background time of the New Testament, sought to find God in emotional experience. The characteristic religious phenomenon of these days was the Mystery Religions. In any view of the history of religion they are an amazing feature. Their aim was union with the divine and they were all in the form of passion plays. They were all founded on the story of some god who lived, and suffered terribly, and died a cruel death, and rose again. The initiate was given a long course of instruction; he was made to practise ascetic discipline. He was worked up to an intense pitch of expectation and emotional sensitivity. He was then allowed to come to a passion play in which the story of the suffering, dying, and rising god was played out on the stage. Everything was designed to heighten the emotional atmosphere. There was cunning lighting; sensuous music; perfumed incense; a marvellous liturgy. In this atmosphere the story was played out and the worshipper identified himself with the experiences of the god until he could cry out: "I am thou, and thou art I"; until he shared the god's suffering and also shared his victory and immortality.

This was not so much knowing God as feeling God. But it was a highly emotional experience and, as such, it was necessarily transient. It was a kind of religious drug. It quite definitely found God in an abnormal experience and its aim was to escape from ordinary life.

(iii) Lastly, there was the Jewish way of knowing God which is closely allied with the Christian way. To the Jew knowledge of God came, not by man's speculation or by an exotic experience of emotion, but by God's own revelation. The God who revealed himself was a holy God and his holiness brought the obligation to his worshipper to be holy, too. A. E. Brooke says, "John can conceive of no real knowledge of God which does not issue in obedience." Knowledge of God can be proved only by obedience to God; and knowledge of God can be gained only by obedience to God. C. H. Dodd says, "To know God is to experience his love in Christ, and to return that love in obedience."

Here was John's problem. In the Greek world he was faced with people who saw God as an intellectual exercise and who could say, "I know God" without being conscious of any ethical obligation whatever. In the Greek world he was faced with people who had had an emotional experience and who could say, "I am in God and God is in me, and who yet did not see God in terms of commandments at all.

John is determined to lay it down quite unmistakably and without compromise that the only way in which we can show that we know God is by obedience to him, and the only way we can show that we have union with Christ is by imitation of him. Christianity is the religion which offers the greatest privilege and brings with it the greatest obligation. Intellectual effort and emotional experience are not neglected--far from it but they must combine to issue in moral action.
