And yet there is a perfectly legitimate use of force also, and a use which our Lord Himself makes of it. We may use force in various circumstances in spite of the fact that for the positive work of the building His Kingdom the Lord rejected it. It is legitimate, in the first place, when it is applied to immature characters—characters which are, as all our characters are in early childhood, a chaos of impulses and instincts, as yet unregulated by any governing principle. Here it may be necessary simply to restrain the activity of one set of impulses without converting the heart or will of the person to whom that restraint is applied, merely in order to give the other side of nature its chance of development. So in education it is legitimate to employ force in this restraining way for the sake of the development which is made possible thereby in the other parts of nature. But our Lord’s example also shows us that the use of force is permissible in dealing with those who are so case-hardened that the appeal of love can never reach them until their present state of mind is broken up. It is sometimes said that the Lord never made use of physical force; but whether or not that is true[#]—the question is unimportant, because for all moral purposes there is no difference whatever between physical and non-physical force. The appeal to force always means the appeal to pain or inconvenience, for these are the only things that force can inflict upon one. Physical force may break a man’s bones; but one may enforce a certain kind of conduct by the threat, for example, of social ostracism, which might break his heart; and there is no difference whatever between the two, except that the second is a more refined form of cruelty. Now in our Lord’s denunciation of the Pharisees, in those words which are thrown, burning and smashing, into the self-complacent contentment of those upholders of tradition, there is every moral quality of force and violence. Their aim is to batter down a state of mind, the state of mind which cannot receive the appeal of love, as it shows when it stands beneath the very Cross and only jeers. But this use of force is only negative and preparatory; it is the effort of love to make ready for the rebuilding which only love’s own method can really accomplish. Only with characters quite immature and liable to develop in many different directions, can force be used, except in this wholly preparatory way; and even there its work is preparatory, for at that stage everything that is done is still preparatory. [#] _e.g._, whether or not He employed the scourge of small cords to drive men from the Temple Courts as He certainly did the animals; the Greek words suggest that He did not.
