But knowledge? The knowledge of God and of Divine things in which good men delight, and which is esteemed the stamina of character--is not this permanent? No, says Paul. "Knowledge also shall be done away." And to illustrate his meaning Paul uses two figures: the figure of a child's knowledge, which is gradually lost in the knowledge of the man, and the figure of an object dimly seen through a semi-transparent medium. We shall understand the significance and the bearing of these figures if we consider that when we speak of imperfect knowledge we may mean either of two things: we may either mean that it is imperfect in amount or that it is imperfect in quality, in accuracy. When a boy begins the study of Euclid, the first proposition he learns is absolutely accurate and true; he may add to it, but he can never improve upon it. His knowledge is imperfect in amount, but so far as it goes it is absolutely reliable; he may build upon it and deduce other truths from it. But when we are walking on a misty morning and see an object at a distance, our knowledge is imperfect, but in quite another sense. It is imperfect in the sense of being dim, uncertain, inaccurate. We see that there is something before us, but whether a human being or a gatepost we cannot say. A little nearer we see it is a human being, but whether old or young, friend or no friend, we cannot say. Here the growth of our knowledge is from dimness to accuracy. Both the figures used by Paul imply that our knowledge of Divine things is of this latter kind. They loom, as it were, through a mist. Many of their details are invisible. We have not got them under our hand to examine at leisure. Our present knowledge is as the light of a lantern by which we can pick our way, or as the starlight, for which we are thankful in the meantime; but when the sun of a wider, deeper, truer knowledge rises, what we now call knowledge shall be quite eclipsed. "When I was a child," says Paul, "I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things." That is to say, Paul was distinctly aware that much of our present knowledge is provisional. We do not know the very truth, but only such approximations to the truth and such symbols of it as we are able to understand. We are at present in the state of childhood, which cherishes many notions destined to be exploded by maturer knowledge. We think of God as a Being very similar to ourselves, only very much greater; and in our present state we must be content with this imperfect knowledge, but prepared to put it away as "childish" when fuller knowledge comes. The atoning death of Christ may be spoken of as the substitutionary sacrifice of a Victim on whom our guilt is laid; but to speak thus of the death of Christ is to make large use of the language of symbol, and we must hold our minds open for the fuller knowledge which will make such language seem quite inadequate.
