Let me put that into other words. We, brethren, are the only beings on this earth who can think the thought and speak the word—Eternity. Other creatures are happy while immersed in time; we have another nature, and are disturbed by a thought which shines high above the roaring sea of circumstance in which we float.
I do not care at present about the metaphysical puzzles that have been gathered round that conception, nor care to ask whether it is positive or negative, adequate or inadequate. Enough that the word has a meaning, that it corresponds to a thought which dwells in men's minds. It is of no consequence at all for our purpose, whether it is a positive conception, or simply the thinking away of all limitations. 'I know what God is, when you do not ask me.' I know what eternity is, though I cannot define the word to satisfy a metaphysician. The little child taught by some grandmother Lois, in a cottage, knows what she means when she tells him 'you will live for ever,' though both scholar and teacher would be puzzled to put it into other words. When we say eternity flows round this bank and shoal of time, men know what we mean. Heart answers to heart; and in each heart lies that solemn thought—for ever!
Like all other of the primal thoughts of men's souls, it may be increased in force and clearness, or it may be neglected and opposed, and all but crushed. The thought of God is natural to man, the thought of right and wrong is natural to man—and yet there may be atheists who have blinded their eyes, and there may be degraded and almost animal natures who have seared their consciences and called sweet bitter and evil good. Thus men may so plunge themselves into the present as to lose the consciousness of the eternal—as a man swept over Niagara, blinded by the spray and deafened by the rush, would see or hear nothing outside the green walls of the death that encompassed him. And yet the blue sky with its peaceful spaces stretches above the hell of waters.
So the thought is in us all—a presentiment and a consciousness; and that universal presentiment itself goes far to establish the reality of the unseen order of things to which it is directed. The great planet that moves on the outmost circle of our system was discovered because that next it wavered in its course in a fashion which was inexplicable, unless some unknown mass was attracting it from across millions of miles of darkling space. And there are 'perturbations' in our spirits which cannot be understood, unless from them we may divine that far-off and unseen world, that has power from afar to sway in their orbits the little lives of mortal men. It draws us to itself—but, alas! the attraction may be resisted and thwarted. The dead mass of the planet bends to the drawing, but we can repel the constraint which the eternal world would exercise upon us—and so that consciousness which ought to be our nobleness, as it is our prerogative, may become our shame, our misery, and our sin.
That Eternity which is set in our hearts is not merely the thought of ever-during Being, or of an everlasting order of things to which we are in some way related. But there are connected with it other ideas besides those of mere duration. Men know what perfection means. They understand the meaning of perfect goodness; they have the notion of infinite Wisdom and boundless Love. These thoughts are the material of all poetry, the thread from which the imagination creates all her wondrous tapestries. This 'capacity for the Infinite,' as people call it—which is only a fine way of putting the same thought as that in our text—which is the prerogative of human spirits, is likewise the curse of many spirits. By their misuse of it they make it a fatal gift, and turn it into an unsatisfied desire which gnaws their souls, a famished yearning which 'roars, and suffers hunger.' Knowing what perfection is, they turn to limited natures and created hearts for their rest. Having the haunting thought of an absolute Goodness, a perfect Wisdom, an endless Love, an eternal Life—they try to find the being that corresponds to their thought here on earth, and so they are plagued with endless disappointment.
My brother! God has put eternity in your heart. Not only will you live for ever, but also in your present life you have a consciousness of that eternal and infinite and all-sufficient Being that lives above. You have need of Him, and whether you know it or not, the tendrils of your spirits, like some climbing plant not fostered by a careful hand but growing wild, are feeling out into the vacancy in order to grasp the stay which they need for their fruitage and their strength.
By the make of our spirits, by the possibilities that dawn dim before us, by the thoughts 'whose very sweetness yieldeth proof that they were born for immortality,'—by all these and a thousand other signs and facts in every human life we say, 'God has set eternity in their hearts!'
II. And then turn to the second idea that is here. The disproportion between this our nature, and the world in which we dwell.
The writer of this book (whether Solomon or no we need not stay to discuss) looks out upon the world; and in accordance with the prevailing tone of all the earlier parts of his contemplations, finds in this prerogative of man but another reason for saying, 'All is vanity and vexation of spirit.'
Two facts meet him antagonistic to one another: the place that man occupies, and the nature that man bears. This creature with eternity in his heart, where is he set? what has he got to work upon? what has he to love and hold by, to trust to, and anchor his life on? A crowd of things, each well enough, but each having a time—and though they be beautiful in their time, yet fading and vanishing when it has elapsed. No multiplication of times will make eternity. And so with that thought in his heart, man is driven out among objects perfectly insufficient to meet it.
