But that is not all. The fire of God is the fire of love as well as the fire of purity; a fire that blesses and quickens, as well as a fire that destroys and consumes. So the Apostle John comes with his answer, not contradicting the other one, but deepening it, expanding it, letting us see the foundations of it, and proclaiming that as a holy God must be surrounded by holy hearts, which will open themselves to the flame as flowers to the sunshine, so a loving God must be clustered about by loving hearts, who alone can enter into deep and true friendship with Him. The two answers, then, of these texts are one at bottom; and when Isaiah asks, 'Who shall dwell with the everlasting fire?'--the perpetual fire, burning and unconsumed, of that divine righteousness--the deepest answer, which is no stern requirement but a merciful promise, is John's answer, 'He that dwelleth in love dwelleth in God.' The simplest way, I think, of bringing out the force of the words before us will be just to take these three points which I have already suggested: the world's question, the partial answer of the prophet, the complete answer of the Apostle. I. The World's Question. I need only remind you how frequently in the Old Testament the emblem of fire is employed to express the divine nature. In many places, though by no means in all, the prominent idea in the emblem is that of the purity of the divine nature, which flashes and flames as against all which is evil and sinful. So we read in one grand passage in this book of Isaiah, 'the Light of Israel shall become a fire'; as if the lambent beauty of the highest manifestation of God gathered itself together, intensified itself, was forced back upon itself, and from merciful, illuminating light turned itself into destructive and consuming fire. And we read, you may remember, too, in the description of the symbolical manifestation of the divine nature which accompanied the giving of the Law on Sinai, that 'the glory of the Lord was like devouring fire on the top of the mountain,' and yet into that blaze and brightness the Lawgiver went, and lived and moved in it.
