The Children Of Light

5:9-14 For once you were darkness, but now you are light in the Lord. You must behave as children of the light, for the fruit of light consists in all benevolence and righteousness and truth. You must decide what is well-pleasing to the Lord. You must take no share in the barren works of the dark. Rather you must expose them, for it is a shameful thing even to speak about the hidden things which are done in secret by such men. Whatever is exposed to the light is illuminated. And everything which is illuminated becomes light. That is why it says: "Wake, O sleeper, and rise from the dead, and Christ will shine upon you."

Paul saw the heathen life as life in the dark; and the Christian life as life in the light. So vividly does he wish to put this that he does not say the heathen are children of the dark and the Christians children of the light; he says the heathen are dark and the Christians are light. He has certain things to say about the light which Jesus Christ brings to men.

(i) The light produces good fruit. It produces benevolence, righteousness and truth. Benevolence (agathosune, Greek #19 ) is a certain generosity of spirit. The Greeks themselves defined righteousness (dikaiosune, Greek #1343 ) as "giving to men and to God that which is their due." Truth (aletheia, Greek #225 ) is not in New Testament thought simply an intellectual thing to be grasped with the mind; it is moral truth, not only something to be known but something to be done. The light which Christ brings makes us useful citizens of this world; it makes us men and women who never fail in duty, human or divine; it makes us strong to do that which we know is true.

(ii) The light enables us to discriminate between that which is well-pleasing and that which is not pleasing to God. It is in the light of Christ that all motives and all actions must be tested. In the bazaars of the east the shops are often simply little covered enclosures with no windows. A man might wish to buy a piece of silk or an article of beaten brass. Before he buys it he takes it out to the street and holds it up to the sun, so that the light might reveal any flaws which happen to be in it. It is the Christian's duty to expose every action, every decision, every motive to the light of Christ.

(iii) The light exposes that which is evil. The best way to rid the world of any evil is to drag it into the light. So long as the thing is being done in secret, it goes on; but when it is taken into the light of day, it dies a natural death. The surest way to cleanse the depths of our own hearts and the practices of any society in which we happen to be involved is to expose them to the light of Christ.

(iv) Finally, Paul says: "Everything which is illuminated becomes light." What he seems to mean is that light has in itself a cleansing quality. In our own generation we know that many a disease has been conquered simply by letting the sunlight in. The light of Christ is like that. We must never think of the light of Christ as only condemnatory; it is a healing thing too.

Paul finishes this passage with a quotation in poetry. In Moffatt's translation it runs:

"Wake up, O sleeper, and rise from the dead;

So Christ will shine upon you."

Paul introduces the quotation as if everybody knew it, but no one now knows where it came from. There are certain interesting suggestions.

Almost certainly, being in poetry, it is a fragment of an early Christian hymn. It may well have been part of a baptismal hymn. In the early Church nearly all baptisms were of adults, confessing their faith as they came out of heathenism into Christianity. Perhaps these were the lines which were sung as they arose from the water, to symbolize the passage from the dark sleep of paganism to the awakened life of the Christian way.

Again, it has been suggested that these lines are part of a hymn, which was supposed to give the summons of the archangel when the last trumpet sounded over the earth. Then would be the great awakening when men rose from the sleep of death to receive the eternal life of Christ.

These things are speculations, but it seems certain that when we read these lines, we are reading a fragment of one of the first hymns the Christian Church ever sang.
