But there is yet another source of certitude open to us all, and that is the history of the centuries. Our modern sceptics, attacking the truth of Christianity mostly from the physical side, are strangely blind to the worth of history. It is a limitation of faculty that besets them in a good many directions, but it does not work anywhere more fatally than it does in their attitude towards the Gospel. After all, Jesus Christ spoke the ultimate word when He said, 'By their fruits ye shall know them.' And it is so, because just as what is morally wrong cannot be politically right, so what is intellectually false cannot be morally good. Truth, goodness, beauty, they are but three names for various aspects of one thing, and if it be that the difference between B.C. and A.D. has come from a Gospel which is not the truth of God, then all I can say is, that the richest vintage that ever the world saw, and the noblest wine of which it ever drank, did grow upon a thorn. I know that the Christian Church has sinfully and tragically failed to present Christ adequately to the world. But for all that, 'Ye are My witnesses, saith the Lord'; and nobler manners and purer laws have come in the wake of this Gospel of Jesus Christ. And as I look round about upon what Christianity has done in the world, I venture to say, 'Show us any system of religion or of no religion that has done that or anything the least like it, and then we will discuss with you the other evidences of the Gospel.'
In closing these words, may I venture relying on the melancholy privilege of seniority, to drop for a minute or two into a tone of advice? I would say, do not be frightened out of your confidence either by the premature paean of victory from the opposite camp, or by timid voices in our own ranks. And that you may not be so frightened, be sure to keep clear in your mind the distinction between the things that can be shaken and the kingdom that cannot be moved. It is bad strategy to defend an elongated line. It is cowardice to treat the capture of an outpost as involving the evacuation of the key of the position. It is a mistake, to which many good Christian people are sorely tempted in this day, to assert such a connection between the eternal Gospel and our deductions from the principles of that Gospel as that the refutation of the one must be the overthrow of the other. And if it turns out to be so in any case, a large part of the blame lies upon those good and mistaken people who insist that everything must be held or all must be abandoned. The burning questions of this day about the genuineness of the books of Scripture, inspiration, inerrancy, and the like, are not so associated with this word, 'God so loved the world ... that whosoever believeth in Him should not perish, but have everlasting life,' as that the discovery of errors in the Second Book of Chronicles shakes the foundations of the Christian certitude. In a day like this truth must change its vesture. Who believes that the Dissenting Churches of England are the highest, perfect embodiment of the Kingdom of God? And who believes that any creed of man's making has in it all and has in it only the everlasting Gospel? So do not be frightened, and do not think that when the things that can be shaken are removed, the things that cannot be shaken are at all less likely to remain. Depend upon it, the Gospel, whose outline I have imperfectly tried to set before you now, will last as long as men on earth know they are sinners and need a Saviour. Did you ever see some mean buildings that have by degrees been gathered round the sides of some majestic cathedral, and do you suppose that the sweeping away of those shanties would touch the solemn majesty of the mediæval glories of the building that rises above them? Take them away if need be, and it, in its proportion, beauty, strength, and heavenward aspiration, will stand more glorious for the sweeping away. Preach positive truth. Do not preach doubts. You remember Mr. Kingsley's book _Yeast_. Its title was its condemnation. Yeast is not meant to be drunk; it is meant to be kept in the dark till the process of fermentation goes on and it works itself clear, and then you may bring it out. Do not be always arguing with the enemy. It is a great deal better to preach the truth. Remember what Jesus said: 'Let them alone, they are blind leaders of the blind, they will fall into the ditch.' It is not given to every one of us to conduct controversial arguments in the pulpit. There are some much wiser and abler brethren amongst us than you or I who can do it. Let us be contented with, not the humbler but the more glorious, office of telling what we have known, leaving it, as it will do, to prove itself. You remember what the old woman, who had been favoured by her pastor with an elaborate sermon to demonstrate the existence of God, said when he had finished; 'Well, I believe there is a God, for all the gentleman says.'
