The fire was the centre, the cloud was wrapped around it. The former was the symbol, making visible to a generation who had to be taught through their senses, the inaccessible holiness and flashing brightness and purity of the divine nature ; the latter tempered and veiled the too great brightness for feeble eyes.
The same double element is found in all God's manifestations of Himself to men. In every form of revelation are present both the heart and core of light, which no eye can look upon, and the merciful veil which, because it veils, unveils; because it hides, reveals; makes visible because it conceals; and shows God because it is' the hiding of His power.' So, through all the history of His dealings with men, there has ever been what is called in Scripture language the face,' or the name of God' ; the aspect of the divine nature on which the eye can look; and manifested through it, there has always been the depth and inaccessible abyss of that Infinite Being. We have to be thankful that in the cloud is the fire, and that round the fire is the cloud. For only so can our eyes behold and our hands grasp the else invisible and remote central Sun of the universe. God hides to make better known the glories of His character. His revelation is the flashing of the uncreated and intolerable light of His infinite Being through the encircling clouds of human conceptions and words, or of deeds which each show forth, in forms fitted to our apprehension, some fragment of His lustre. After all revelation, He remains unrevealed. After ages of showing forth His glory, He is still' the King invisible, whom no man hath seen at any time nor can see.' The revelation which He makes of Himself is truth and"is no lie.' The recognition of the presence in it of both the fire and the cloud does not cast any doubt on the reality of our imperfect knowledge, or of the authentic participation in the nature of the central light, of the sparkles of it which reach us. We know with a real knowledge what we know of Him. What He shows us is Himself, though not His whole Self.
This double aspect of all possible revelation of God, which was symbolised in comparatively gross external form in the pillar that led Israel on its march, and lay stretched out and quiescent, a guarding covering above the Tabernacle when the weary march was still, recurs all through the history of Old Testament revelation by type and prophecy and ceremony, in which the encompassing cloud was comparatively dense, and the light which pierced it relatively faint. It reappears in both elements in Christ, but combined in new proportions, so as that the veil, that is to say, His flesh,' is thinned to transparency and all aglow with the indwelling lustre of manifest Deity. So a light, set in some fair alabaster vase, shines through its translucent walls, bringing out every delicate tint and meandering vein of colour, while itself diffused and softened by the enwrapping medium which it beautifies by passing through its purity. Both are made visible and attractive to dull eyes by the conjunction. He that hath seen Christ hath seen the Father,' and he that hath seen the Father in Christ hath seen the man Christ, as none see Him who are blind to the incarnate deity which illuminates the manhood in which it dwells.
But we have to note also the varying appearance of the pillar according to need. There was a double change in the pillar according to the hour, and according as the congregation was on the march or encamped. By day it was a cloud, by night it glowed in the darkness. On the march it moved before them, an upright pillar, as gathered together for energetic movement; when the camp rested it' returned to the many thousands of Israel' and lay quietly stretched above the Tabernacle like one of the long-drawn, motionless clouds above the setting summer sun, glowing through all its substance with unflashing radiance reflected from unseen light, and on all the glory' (shrined in the Holy Place beneath) was a defence.'
Both these changes of aspect symbolise for us the reality of the Protean capacity of change according to our ever-varying needs, which for our blessing we may find in that ever-changing, unchanging, divine Presence which will be our companion, if we will.
It was not only by a natural process that, as daylight declined, what had seemed but a column of smoke in the fervid desert sunlight, brightened into a column of fire, blazing amid the clear stars. But we may well believe in an actual admeasurement of the degree of light, correspondent to the darkness and to the need for certitude and cheering sense of God's protection, which the defenceless camp would feel as they lay down to rest.
When the deceitful brightness of earth glistens and dazzles around us, our vision of Him may be a cloudy screen to temper the deceitful ray'; and when' there stoops on our path, in storm and shade, the frequent night,' as earth grows darker, and life becomes greyer and more sombre, and verges to its eventide, the pillar blazes brighter before the weeping eye, and draws nearer to the lonely heart. We have a God who manifests Himself in the pillar of cloud by day, and in flaming fire by night.
