The Last Words of the Last Apostle
1 John 5:20
And we know that the Son of God is come, and has given us an understanding, that we may know him that is true…


I. HERE WE HAVE THE SUM OF ALL THAT WE NEED TO KNOW ABOUT GOD. "This is the true God." When he says, "This is the true God" he means to say, "This God of whom I have been affirming that Jesus Christ is His sole Revealer, and of whom I have been declaring that through Jesus Christ We may know Him and dwell abidingly in Him." "This" — and none else — "is the true God." What does John mean by "true"? By that expression he means, wherever he uses it, some person or thing whose nature and character correspond to his or its name, and who is essentially and perfectly that which the name expresses. If we take that as the signification of the word, we just come to this, that the God revealed in Jesus Christ, and with whom a man through Jesus Christ may have fellowship of knowledge and friendship, that He and none but He answers to all that men mean when they speak of a God; that He, if I might use such expressions, fully fills the part. If we only think that, however it comes (no matter about that) every man has in him a capacity of conceiving of a perfect being, of righteousness, power, purity, and love, and that all through the ages of the world's yearnings there has never been presented to it the embodiment of that dim conception, but that all idolatry, all worship, has failed in bodying out a person who would answer to the requirements of a man's spirit, then we come to the position in which these final words of the old fisherman go down to a deeper depth than all the world's wisdom, and carry a message of consolation and a true gospel to be found nowhere besides. Whatsoever embodiments men may have tried to give to their dim conception of a God, these have been always limitations, and often corruptions of it. And to limit or to separate is, in this case, to destroy. No Pantheon can ever satisfy the soul of man who yearns for One Person in whom all that he can dream of beauty, truth, goodness shall be ensphered. "This is the true God." And all others are corruptions, or limitations, or divisions, of the indissoluble unity. Then are men to go forever and ever with the blank misgivings of a creature moving about in worlds not realised? For, consider what it is that the world owes to Jesus Christ in its knowledge of God. Remember that to us as orphaned men He has come and said, as none ever said, and showed as none ever showed: "Ye are not fatherless, there is a Father in the heavens." "God is a Spirit." "God is love." And put these four revelations together, the Father; Spirit; unsullied Light; absolute Love; and then let us bow down and say, "Thou hast said the truth, O aged Seer." This is our God; we have waited for Him, and He will save us. "This" — and none beside — "is the true God." I know not what the modern world is to do for a God if it drifts away from Jesus Christ and His revelations.

II. HERE WE HAVE THE SUM OF HIS GIFTS TO US. "This is the true God, and eternal life." By "eternal life" He means something a great deal more august than endless existence. He means a life which not only is not ended by time, but which is above time, not subject to its conditions at all. Eternity is not time spun out forever. That seems to part us utterly from God. He is "eternal life"; then, we poor creatures down here, whose being is all "cribbed, cabin'd, and confined" by succession, and duration, and the partitions of time, what can we have in common with Him? John answers for us. For remember that in the earlier part of this Epistle he writes that "the life was manifested, and we show unto you that eternal life which was with the Father, and was manifested unto us, and we declare it unto you; and we declare it unto you, that ye also may have fellowship with us, and our fellowship is with the Father, and with His Son." But we are not left to wander about in regions of mysticism and darkness. For we know this, that however strange and difficult the thought of eternal life, as possessed by a creature, may be, to give it was the very purpose for which Jesus Christ came on earth. "I am come that they might have life, and have it more abundantly." And we are not left to grope in doubt as to what that eternal life consists in; for He has said: "This is life eternal, that they might know Thee, the only true God, and Jesus Christ whom Thou hast sent." Thus, then, there is a life which belongs to God on His throne, a life lifted above the limitations of time, a life communicated by Jesus Christ, as the waters of some land locked lake may flow down through a sparkling river, a life which consists in fellowship with God, a life which may be, and is, ours, on the simple condition of trusting Him who gives it, and a life which, eternal as it is, is destined to a future all undreamed of, in that future beyond the grave, is now the possession of every man that puts forth the faith which is its condition.

III. Lastly, WE HAVE HERE THE CONSEQUENT SUM OF CHRISTIAN ACTION. "Little children, keep yourselves from 'idols'" — seeing that "this is the true God" — the only One that answers to your requirements, and will satisfy your desires. Do not go rushing to these shrines of false deities that crowd every corner of Ephesus — ay! and every corner of Manchester. Is the exhortation not needed? In Ephesus it was hard to have nothing to do with heathenism. In that ancient world their religion, though it was a superficial thing, was intertwined with daily life in a fashion that puts us to shame. Every meal had its libation, and almost every art was knit by some ceremony or other to a god. So that Christian men and women had almost to go out of the world in order to be free from complicity in the all-pervading idol worship. You and I call ourselves Christians. We say we believe that there is nothing else, and nobody else, in the whole sweep of the universe that can satisfy our hearts, or be what our imagination can conceive but God only. Having said that on the Sunday, what about Monday? "They have forsaken Me, the Fountain of living water, and hewed to themselves broken cisterns that can hold no water." "Little children" — for we are scarcely more mature than that — "little children, keep yourselves from idols." And how is it to be done? "Keep yourselves." Then you can do it, and you have to make a dead lift of an effort, or be sure of this — that the subtle seduction will slide into your heart, and before you know it you will be out of God's sanctuary, and grovelling in Diana's temple. But it is not only our own effort that is needed, for just a sentence or two before, the apostle had said: "He that is born of God" — that is, Christ — "keepeth us." So our keeping of ourselves is essentially our letting Him keep us. Here is the sum of the whole matter. There is one truth on which we can stay our hearts, on God in whom we can utterly trust, the God revealed in Jesus Christ. If we do not see Him in Christ we shalt not see Him at all, but wander about all our days in a world empty of solid reality.

(A. Maclaren, D. D.)
