If a doctor knows that he can cure a disease he can afford to give full weight to its gravest symptoms. If he knows he cannot he is sorely tempted to say it is of slight importance, and, though it cannot be cured, can be endured without much discomfort. And so the Scripture teachings about man's real moral condition are characterised by two peculiarities which, at first sight, seem somewhat opposed, but are really harmonious and closely connected. There is no book and no system in the whole world that takes such a dark view of what you and I are; there is none animated with so bright and confident a hope of what you and I may become. And, on the other hand, the common run of thought amongst men minimises the fact of sin, but when you say, 'Well, be it big or little, can I get rid of it anyhow?' there is no answer to give that is worth listening to. Christ alone can venture to tell men what they are, because Christ alone can radically change their whole nature and being. There are certain diseases of which a constant symptom is unconsciousness that there is anything the matter. A deep-seated wound does not hurt much. The question is not whether Christian thoughts about a man's condition are gloomy or not, but whether they are true. As to their being gloomy, it seems to me that the people who complain of our doctrine of human nature, as giving a melancholy view of men, do really take a far more melancholy one. We believe in a fall, and we believe in a possible and actual restoration. The man to whom evil is not an intrusive usurper can have no confidence that it will ever be expelled. Which is the gloomy system--that which paints in undisguised blackness the facts of life, and over against their blackest darkness, the radiant light of a great hope shining bright and glorious, or one that paints humanity in a uniform monotone of indistinguishable grey involving the past, the present, and the future--which, believing in no disease, hopes for no cure? My text, taken in conjunction with the grand words which follow, about 'The new man, which, after God, is created in righteousness and true holiness,' brings before us some very solemn views (which the men that want them most realise the least) with regard to what we are, what we ought to be and cannot be, and what, by God's help, we may become. The old man is 'corrupt according to the deceitful lusts,' says Paul. _There_ are a set of characteristics, then, of the universal sinful human self. Then there comes a hopeless commandment--a mockery--if we are to stop with it, 'put it off.' And then there dawns on us the blessed hope and possibility of the fulfilment of the injunction, when we learn that 'the truth in Jesus' is, that we put off the old man with his deeds. Such is a general outline of the few thoughts I have to suggest to you. I. I wish to fix, first of all, upon the very significant, though brief, outline sketch of the facts of universal sinful human nature which the Apostle gives here.
