When it lifts the camp marches; when it glides down and lies motionless the march is stopped, and the tents are pitched. The main point which is dwelt upon in this description of the God-guided pilgrimage of the wandering people is the absolute uncertainty in which they were kept as to the duration of their encampment, and as to the time and circumstances of their march. Sometimes the cloud tarried upon the Tabernacle many days; sometimes for a night only; sometimes it lifted in the night. Whether it was by day or by night that the cloud was taken up, they journeyed. Or whether it were two days, or a month, or a year that the cloud tarried upon the Tabernacle, remaining thereon, the children of Israel abode in their tents, and journeyed not: but when it was taken up they journeyed.' So never, from moment to moment, did they know when the moving cloud might settle, or the resting cloud might soar. Therefore, absolute uncertainty as to the next stage was visibly represented before them by that hovering guide which determined everything, and concerning whose next movement they knew absolutely nothing.
Is not that all true about us? We have no guiding cloud like this. So much the better. Have we not a more real guide? God guides us by circumstances, God guides us by His word, God guides us by His Spirit, speaking through our common-sense and in our understandings, and, most of all, God guides us by that dear Son of His, in whom is the fire and round whom is the cloud. And perhaps we may even suppose that our Lord implies some allusion to this very symbol in His own great words, I am the Light of the world. He that followeth Me shall not walk in darkness, but shah have the light of life.' For the conception of following' the light seems to make it plain that our Lord's image is not that of the sun in the heavens, or any such supernal light, but that of some light which comes near enough to a man to move before him, and behind which he can march. So, I think, that Christ Himself laid His hand upon this ancient symbol, and in these great words said in effect, I am that Which it only shadowed and foretold.' At all events, whether in them He was pointing to our text or no, we must feel that He is the reality which was expressed by this outward symbol. And no man who can say, Jesus Christ is the Captain of my salvation, and after His pattern I march ; at the pointing of His guiding finger I move; and in His footsteps, He being my helper, I try to tread,' need feel or fancy that any possible pillar, floating before the dullest eye, was a better, surer, or diviner guide than he possesses. They whom Christ guides want none other for leader, pattern, counsellor, companion, reward. This Christ is our Christ for ever and ever, He will be our guide even unto death' and beyond it. The pillar that we follow, which will glow with the ruddy flame of love in the darkest hours of life, blessed be His name! will glide in front of us through the valley of the shadow of death,' brightest then when the murky midnight is blackest. Nor will the pillar which guides us cease to blaze, as did the guide of the desert march, when Jordan has been crossed. It will still move before us on paths of continuous and ever-increasing approach to infinite perfection. They who here follow Christ afar off and with faltering steps shall there follow the Lamb whithersoever He goeth.'
In like manner, the same absolute uncertainty which was intended to keep the Israelites (though it failed often to do so) in the attitude of constant dependence, is the condition in which we all have to live, though we mask it from ourselves. That we do not know what lies before us is a commonplace. The same long tracts of monotonous continuance in the same place and doing the same duties befall us that befell these men. Years pass, and the pillar spreads itself out, a defence above the unmoving sanctuary. And then, all in a flash, when we are least thinking of change, it gathers itself together, is a pillar again, shoots upwards, and moves forwards; and it is for us to go after it. And so our lives are shuttlecocked between uniform sameness which may become mechanical monotony, and agitation by change which may make us lose our hold of fixed principles and calm faith, unless we recognise that the continuance and the change are alike the will of the guiding God, whose will is signified by the stationary or moving pillar.
