And then come others, and they say, 'Environment is the thing that is to blame for it all. How can you get decent lives in the slums?' No, I know you cannot; and God bless every effort made to get the people out of the slums, I say. Only do not let us exaggerate. You cannot change a man, as deeply as we need to be changed, by any change of his circumstances. 'Take the bitter tree,' as I remember an old Jewish saying has it, 'take the bitter tree and plant it in Eden, and water it with the rivers there; and let the angel Gabriel be the gardener, and the tree will still bear bitter fruit.' Are all the people who live in good houses good? Will a 'living wage'--eight shillings a day and eight hours' play--will these change a man's character? Will these go deep enough down to touch the springs of evil? You cannot alter the nature of a set of objects by arranging them in different shapes, parallelograms, or squares, or circles, or any others. As long as you have the elements that are in human nature to deal with, you may do as you like about the distribution of wealth, and the relation of Capital to Labour, and the various cognate questions which are all included in the vague word Socialism; and human nature will be too strong for you, and you will have the old mischiefs cropping out again. Brethren, you cannot put out Vesuvius by bringing to bear on it the squirts of all the fire engines in creation. The water will go up in steam, and do little or nothing to extinguish the fire. And whilst I would thankfully help in all these other movements, and look for certain limited results of good from them, I, for my part, believe, and therefore I am bound to declare, that neither singly, nor all of them in combination, will they ever effect the change on human nature which Jesus Christ regarded as the only possible means for securing that human nature should bear good fruit. For, if there were no other reason, there are two plain ones which I only touch. God is the source of all good, of all creatural purity as well as all creatural blessedness. And if a life has a blank wall turned to Him, and has cut itself off from Him, I do not care how you educate it, fill it full of science, plunge it into an atmosphere of art, make the most perfect arrangements for social and economical and political circumstances, that soul is cut off from the possibility of good, because it is cut off from the fontal source of all good. And there is another reason which is closely connected with this, and that is that the true bitter tang in us all is self-centring regard. That is the mother-tincture that, variously coloured and compounded, makes in all the poisonous element that we call sin, and until you get something that will cast that evil out of a man's heart, you may teach and refine and raise him and arrange things for him as you like, and you will not master the source of all wrong and corrupt fruit. III. Lastly, let me say a word about the triumphant solution.
