The tone and language which befits such a dedicated life is the tone and language of thanksgiving. But clearly Asiatic Christians were only too ready to forget the essential incompatibility of their new profession with the old sinful habits around them. So St. Paul emphasizes 'This ye know for certain that fornication or unclean living on the one hand, or the turning of gain into a god on the other, surely excludes a man from the kingdom of Christ and God[[1]].' And he reiterates 'let no man deceive you with empty words.' Such vices, being in plain contradiction to the divine will, make men subjects of the divine wrath, and for you this should be startlingly plain. You have been brought out of the realm of darkness of which once you formed a part, into the realm of light, of which you now form a part, the realm whose light is Christ. There is no fellowship between the light and the darkness[[2]]. To live in the light means to bring forth fruit of goodness and righteousness and truth, the fruit of a character like Christ's. For you have in Christ a definite standard by which you can test what is well pleasing to the Lord. It is your business, therefore, to keep yourselves altogether separate from the works of darkness which bear no fruit. Not only so, but it is your business to 'reprove' or convict the dark world of sin; not, of course, by making the works of darkness the subjects of your curiosity and conversation—that indeed must not be—but simply by the contrast which your own lives present. In the light of your lives the secret shame of the heathen life will be unmasked. And in being unmasked even the works of darkness will themselves become part of the light. To make such ways of living attractive they must be cloaked up in a deceitful glamour. Once stripped bare and shown in their true character they teach their true lesson. Thus, the one duty of a man is to awake from the old sleep of death; to separate himself from the morally dead world and stand clear in the light of Christ. And that is what the early Christian hymn, which St. Paul cites, was continually impressing upon the Christian conscience. We may attempt to reproduce it in something like its original rhythm thus:—
'Be awakened, thou that sleepest;
Rise alive from out the dead world;
Christ, the Light, shall shine upon thee.'
Be ye therefore imitators of God, as beloved children; and walk in love, even as Christ also loved you, and gave himself up for us, an offering and a sacrifice to God for an odour of a sweet smell. But fornication, and all uncleanness, or covetousness, let it not even be named among you, as becometh saints; nor filthiness, nor foolish talking, or jesting, which are not befitting: but rather giving of thanks. For this ye know of a surety, that no fornicator, nor unclean person, nor covetous man, which is an idolater, hath any inheritance in the kingdom of Christ and God. Let no man deceive you with empty words: for because of these things cometh the wrath of God upon the sons of disobedience. Be not ye therefore partakers with them; for ye were once darkness, but are now light in the Lord: walk as children of light (for the fruit of the light is in all goodness and righteousness and truth), proving what is well-pleasing unto the Lord; and have no fellowship with the unfruitful works of darkness, but rather even reprove them; for the things which are done by them in secret it is a shame even to speak of. But all things when they are reproved are made manifest by the light: for everything that is made manifest is light. Wherefore he saith, Awake, thou that sleepest, and arise from the dead, and Christ shall shine upon thee.
Three points may be noticed in this characteristic exhortation:—
1. The strife of light and darkness. The victory of the rising sun and its surrender at evening to the darkness; the obscuring of the light through eclipse or mist and its recovery—these universal appearances present themselves naturally to human consciences everywhere as being experiences analogous to the moral strife within between good and evil. Light is thus the universal symbol of good, and darkness of evil. The symbolism passes out of early native myths into the spiritual phraseology of many religions; but especially into those of the Persians and the Jews. 'In thy light shall we see light' is the cry of the devout heart towards God. And the whole of Christian language is possessed by the symbolism. Christ is 'the light of the world': His disciples are 'the children of light,' they are to be clothed in 'the armour of light,' bathed in 'the light of the glorious Gospel': they are the children of the God who 'dwelleth in the light which no man can approach unto': who 'is light and in whom is no darkness at all.'
St. Paul, like St. John, specially loves the metaphor of light. And it is somewhat startling to notice how different is his conception of enlightenment from that common in modern times, or indeed, from that held in the schools of philosophy of his own day or by the Gnostics just after him. This latter class of men, who can be taken as typical of many others at very different epochs, meant by 'the enlightened' a select few who had a special capacity for intellectual abstraction and contemplation, and who by such qualities of the intellect were believed to attain to a knowledge of God which was beyond the reach of the ordinary men of faith. But St. Paul, following his Master, is quite certain that the root of true enlightenment lies in the will and heart. The love of the light is first of all simply the pure desire for goodness; and anything that is not this first of all is a counterfeit and a sham. And the true enlightenment is thus not the privilege of a few, but is open to all who will come to Christ. 'Where is the wise? where is the scribe? where is the disputer of this world? Hath not God made foolish the wisdom of this world? For seeing that in the wisdom of God the world through its wisdom knew not God, it was God's good pleasure, through the foolishness of the preaching, to save them that believe.' 'If any man thinketh that he is wise among you in this world, let him become a fool that he may become wise. For the wisdom of this world is foolishness with God[[3]].' This language sounds violent; but I doubt if many thinking men could now be found to doubt that the way opened by the 'foolishness of the gospel preaching' was a way of light for the world compared to which the way of the contemporary philosophers was darkness and delusion. The arrogant wisdom of the contemporary 'Heracleitus' would have provided no real light at all for the Ephesians whom he denounced. A fresh start was wanted for man, and the fresh start was primarily in the life of the conscience and heart. On the other hand neither St. Paul, nor any of the New Testament writers, can be accused of the sort of obscurantism to which the later Church has often fallen a victim. One cannot even conceive St. Paul denouncing free inquiry, or cloaking up from free investigation the title-deeds of Christianity. His love of the light—even with all the dangers that the light has—like his love of freedom, is frank and real.
If we come down to our own time, there is no doubt a great deal of contemporary 'enlightenment' that St. Paul would have pronounced spurious. He would never surely have disparaged intellectual inquiry or free scientific research: but he would have continually emphasized that no one was really enlightened whose will and heart was not right with God. To have a scientific knowledge of facts is by comparison superficial; and worse than superficial is the sharpness and worldly cleverness which continually boasts of being 'wide awake' and 'up to date.' It is possible to be awake and enlightened in the speculative and practical intelligence: to be awake and enlightened in the region of the senses: and yet to be asleep and in the dark in the region of the will and conscience towards God. And there lies the true heart of manhood. It is possible even to be enlightened about evil and in the dark as regards goodness. But St. Paul hates curiosity about the ways and methods of sin. 'I would,' he says, 'have you wise unto that which is good, and simple unto that which is evil[[4]].' Take heed that the light that is in thee be not darkness. This curiosity about sin is a delusion which has sometimes a strange hold on some who would serve God. But they must recognize that the only Christian method of 'convicting the world of sin' is by 'convicting it of righteousness.' Innocence has a power which sometimes is strangely underrated.
We may pause for a moment longer to dwell on the beauty of St. Paul's ideal of Christianity as a life in the light. It has everything to gain and nothing to lose by disclosure. It has no need to cloak itself. It can be frank with itself and the world. And, on the other hand, sin is a great fraud and delusion as well as a great disobedience. It dwells in a region of lies and excuses and concealments; it hides from itself and from the world its true character and true issues. For, in fact, it is not only in itself foul and rebellious, but it is in its issues fruitless. It leads to nothing: it produces nothing: it tends only to decay or corruption of mind and body, while goodness is only another term for life and fruitfulness. Life, and the production of life, is the good, and it belongs to the light; on the contrary, what hinders or destroys life goes against God and belongs to the darkness. This is a judgement which mis-called disciples of Malthus in our day would do well to remember. It is not from too much life that the world is suffering, but from corrupt and perverted life. What we want to secure is not a limit to the population, but the bringing up of children in health and simple living, in the nurture and admonition of the Lord.
2. St. Paul, in some passages of his epistles, uses very strongly 'universalist' phrases. He has spoken to the Ephesians of bringing all things in heaven and earth again into a divine unity in Christ. And to the Corinthians he spoke of a time when God should be 'all things in all.' It is, therefore, all the more noticeable that when he comes to speak of the destiny of evil men he does not offer them any hope if they persist in their evil, but warns them that moral evil utterly and wholly excludes from the kingdom of God: and he appears to be not at all anxious to reconcile this warning as to the eternal consequences of wilful evil with what he has said in other connexions as to the final inclusion of all things in a great unity. His example would teach us to aim at being true to the whole truth rather than at attaining a premature completeness or consistency of knowledge about a world in regard to which we only 'know in part.' 'Yea, the more part of God's works are hid[[5]].'
