The significance of this bush, burning but not consumed, is my main subject now, for I think it carries great and blessed lessons for us.
Now, first, I do not think that the bush burning but not consumed, stands as it is ordinarily understood to stand, for the symbolical representation of the preservation of Israel, even in the midst of the fiery furnace of persecution and sorrow.
Beautiful as that idea is, I do not think it is the true explanation; because if so, this symbol is altogether out of keeping with the law that applies to all the rest of the symbolical accompaniments of divine appearances, all of which, without exception, set forth in symbol some truth about God, and not about His Church; and all of which, without exception, are a representation in visible and symbolical form of the same truth which was proclaimed in articulate words along with them. The symbol and the accompanying voice of God in all other cases have one and the same meaning.
That, I think, is the case here also; and we learn from the Bush, not something about God's Church, however precious that may be, but what is a great deal more important, something about God Himself; namely, the same thing that immediately afterwards was spoken in articulate words.
In the next place, let me observe that the fire is distinctly a divine symbol, a symbol of God not of affliction, as the ordinary explanation implies. I need not do more than remind you of the stream of emblem which runs all through Scripture, as confirming this point. There are the smoking lamp and the blazing furnace in the early vision granted to Abraham. There is the pillar of fire by night, that lay over the desert camp of the wandering Israelites. There is Isaiah's word, 'The light of Israel shall be a flaming fire.' There is the whole of the New Testament teaching, turning on the manifestation of God through His Spirit. There are John the Baptist's words, 'He shall baptize you with the Holy Ghost and with fire.' There is the day of Pentecost, when the 'tongues of fire sat upon each of them.' And what is meant by the great word of the Epistle to the Hebrews, 'Our God is a consuming fire'?
Not Israel only, but many other lands—it would scarcely be an exaggeration to say, all other lands—have used the same emblem with the same meaning. In almost every religion on the face of the earth, you will find a sacred significance attached to fire. That significance is not primarily destruction, as we sometimes suppose, an error which has led to ghastly misunderstandings of some Scriptures, and of the God whom they reveal. When, for instance, Isaiah (xxxiii. 14) asks, 'Who among us shall dwell with the devouring fire? who among us shall dwell with everlasting burnings?' he has been supposed to be asking what human soul is there that can endure the terrors of God's consuming and unending wrath. But a little attention to the words would have shown that 'the devouring fire' and the 'everlasting burnings' mean God and not hell, and that the divine nature is by them not represented as too fierce to be approached, but as the true dwelling-place of men, which indeed only the holy can inhabit, but which for them is life. Precisely parallel is the Psalmist's question, 'Who shall ascend into the hill of the Lord, and who shall stand in His holy place?'
Fire is the source of warmth, and so, in a sense, of life. It is full of quick energy, it transmutes all kinds of dead matter into its own ruddy likeness, sending up the fat of the sacrifices in wreathes of smoke that aspire heavenward; and changing all the gross, heavy, earthly dullness into flame, more akin to the heaven into which it rises.
Therefore, as cleansing, as the source of life, light, warmth, change, as glorifying, transmuting, purifying, refining, fire is the fitting symbol of the mightiest of all creative energy. And the Bible has consecrated the symbolism, and bade us think of the Lord Himself as the central fiery Spirit of the whole universe, a spark from whom irradiates and vitalises everything that lives.
Nor should we forget, on the other side, that the very felicity of this emblem is, that along with all these blessed thoughts of life-giving and purifying, there does come likewise the more solemn teaching of God's destructive power. 'What maketh heaven, that maketh hell'; and the same God is the fire to quicken, to sanctify, to bless; and resisted, rejected, neglected, is the fire that consumes; the savour of life unto life, or the savour of death unto death.
And then, still further, notice that this flame is undying—steady, unflickering. What does that mean? Adopting the principle which I have already taken as our guide, that the symbol and the following oral revelation teach the same truth, there can be no question as to that answer. 'I am the God of thy fathers, the God of Abraham, of Isaac, and of Jacob. 'I AM THAT I AM.'
