For love loves unto purity. Love has ever in view the absolute loveliness of that which it beholds. Where loveliness is incomplete, and love cannot love its fill of loving, it spends itself to make more lovely, that it may love more; it strives for perfection, even that itself may be perfected--not in itself, but in the object. As it was love that first created humanity, so even human love, in proportion to its divinity, will go on creating the beautiful for its own outpouring. There is nothing eternal but that which loves and can be loved, and love is ever climbing towards the consummation when such shall be the universe, imperishable, divine. Therefore all that is not beautiful in the beloved, all that comes between and is not of love's kind, must be destroyed. And our God is a consuming fire. If this be hard to understand, it is as the simple, absolute truth is hard to understand. It may be centuries of ages before a man comes to see a truth--ages of strife, of effort, of aspiration. But when once he does see it, it is so plain that he wonders he could have lived without seeing it. That he did not understand it sooner was simply and only that he did not see it. To see a truth, to know what it is, to understand it, and to love it, are all one. There is many a motion towards it, many a misery for want of it, many a cry of the conscience against the neglect of it, many a dim longing for it as an unknown need before at length the eyes come awake, and the darkness of the dreamful night yields to the light of the sun of truth. But once beheld it is for ever. To see one divine fact is to stand face to face with essential eternal life. For this vision of truth God has been working for ages of ages. For this simple condition, this apex of life, upon which a man wonders like a child that he cannot make other men see as he sees, the whole labour of God's science, history, poetry--from the time when the earth gathered itself into a lonely drop of fire from the red rim of the driving sun-wheel to the time when Alexander John Scott worshipped him from its face--was evolving truth upon truth in lovely vision, in torturing law, never lying, never repenting; and for this will the patience of God labour while there is yet a human soul whose eyes have not been opened, whose child-heart has not yet been born in him. For this one condition of humanity, this simple beholding, has all the outthinking of God flowed in forms innumerable and changeful from the foundation of the world; and for this, too, has the divine destruction been going forth; that his life might be our life, that in us, too, might dwell that same consuming fire which is essential love. Let us look at the utterance of the apostle which is crowned with this lovely terror: "Our God is a consuming fire."
