Let me supply proof here of what I state. For all the life of him, the learnéd doctor won't be able to. How true the maxim that The wish often father's the thought. I deal in facts. Here's the proof.
It has sometimes been said that Spurgeon's Calvinism waned as he grew older. This page will refute this bogus claim. It is not so much that his Calvinism waned, but it did not become the main battle ground on which he fought in later years. His last years were taken up with the famous Downgrade controversy where he was busy defending the fundamentals of the gospel e.g. the Inspiration of Scripture and the Deity of Christ etc., rather than the Doctrines of Grace. Many Wesleyans were glad to stand with him in his matter. However he did maintain his belief in the Calvinist cause right to the end and the quotes below are given from his sermons etc., all drawn from the last few years of his life. He died in January 31st 1892. He preached his last sermon in the Metropolitan Tabernacle on June 7th 1891, (No. 2208) This appears in Volume 37 (37:398) A great excess of Spurgeon's sermons enabled the MTP to be published until 1917. No less than 62 volumes were eventually published. It would take too long to trace from the sermons printed after Spurgeon's death any references he made to Calvinism in his last years. We may rest content from the evidence below that he never wavered, but maintained these glorious old doctrines right to the end.
"I do not know in what other way to preach from this text than the one in which I am preaching from it. Somebody says, “Oh, that is Calvinism!” I do not care what it is. It is Scriptural. I have this inspired Book before me, and I cannot see any meaning in the words before me, if they do not mean that those who have received life from the Lord Jesus have an endless inheritance. I cannot make them mean anything else. “I give unto my sheep eternal life,” must mean that believers are eternally secure. “It is dangerous doctrine,” cries one. I have not found it dangerous, and I have tried it these many years." (Sermon entitled: Eternal Security or Sheep who shall never perish (35:876)
"There is not another gospel that I know of that is worth the comparison for a single minute. Oh, but, they say, there is a gospel that is much wider than yours. Yes, I know that it is much wider than mine; but to what does it lead? They say that what is nicknamed Calvinism has a very narrow door. There is a word in Scripture about a strait gate and a narrow way; and therefore I am not alarmed by the accusation. But then there are rich pastures when you enter within, and this renders it worth while to enter in by the strait gate. Certain other systems have very wide doors; but they lead you into small privileges, and those of a precarious tenure. I hear certain invitations which might run as follows: — Come ye disconsolate; but if you come, you will be disconsolate still, for there will be no eternal made sure to you, and you must preserve your own souls, or perish after all. But I shall not enter into any comparisons, for they are odious in this case." (37:60)
"It is well for the preacher to remind men that they are lost by nature, and that in their flesh there dwelleth no good thing. It is well that sin should be made to appear sin, and that self righteousness should be made to look like filthy rags. Human inability and the need of the Holy Spirit, must be set forth clearly, and the sovereignty of God must be proclaimed solemnly. The Lord has a right to pass over whom he pleases; but if mercy comes to any man it will be by the sovereign act of God — because God wills to do it, and not because any man deserves it." (36:191)
"The doctrines of grace which I have preached to you have a hold upon the heart and intellect, like that of certain colours when the wool is dyed ingrain. Because these doctrines have not been sufficiently preached, our people are easily carried away with every wind of doctrine, Brethren, the old evangelical doctrine of Luther and Calvin had about it power to create enthusiasm. See how the Huguenots mustered to a sermon when it was death to hear a reformed preacher. Geneva sent forth men who could gather crowds in regions crimsoned with the blood of their brethren. Why did the multitudes come together? Would any man jeopardize his life to hear a “modern-thought” sermon? My brethren, there is something in the old gospel worth hearing: there is an election of grace most precious, a redemption which really redeemed, and a work of grace within which ensures final perseverance and eternal glory." (35:773)
"High doctrine is glorious doctrine, high experience is blessed experience, high holiness is heavenly living. Many souls always keep in the plains: the simple elements are enough for them; and, thank God, they are enough for salvation and for comfort. But if you want the richest delight and the highest degree of grace, climb the hills and roam among the mysteries of God, the sublimer revelations of his divine will. Especially climb into the doctrines of grace: be not afraid of electing love, of special redemption, of the covenant, and all that is contained in it. Be not afraid to climb high, for if thy feet be dipped in the oil of grace, they shall also be so shod that they shall not slip. Trust in God, and you shall be as Mount Zion, which can never be removed. Your shoes shall be iron and brass, for lofty thought and clear knowledge, if you commit your mind to the instruction of the Lord. Receiving nothing except as you find it in the Word, but in a childlike spirit receiving everything that you find there, you shall stand upon your high places. Your feet shall be like hinds’ feet, and your place of abode shall be above the mists and clouds of earth’s wretched atmosphere of doubt." (35:9)
