There have been many opinions as to the meaning of the lamps and the oil, which it is needless to repeat. Surely the analogy of scriptural symbolism is our best guide. If we follow it, we get a meaning which perfectly suits the emblems and the whole parable. In the Sermon on the Mount, our Lord uses the same figure of the lamp, and explains it: 'Let your light shine before men, that they may see your good works.'
II. Note the sleep of all the virgins. No blame is hinted on account of it. It is not inconsistent with the wisdom of the wise, nor does it interfere with their readiness to meet the bridegroom. It is, then, such a sleep as is compatible with watching. Our Lord's introduction of this point is an example of His merciful allowance for our weakness. There must be a certain slackening of the tension of expectation when the bridegroom tarries. Centuries of delay cannot but modify the attitude of the waiting Church, and Jesus here implies that there will be a long stretch of time before His advent, during which all His people will feel the natural effect of the deferring of hope. But the sleep which He permits, unblamed, is light, and such as one takes by snatches when waiting to be called. He does not ask us always to be on tiptoe of expectation, nor to refuse the teaching of experience; but counts that we have watched aright, if we wake from our light slumbers when the cry is heard, and have our lamps lit, ready for the procession.
III. Then comes the midnight cry and the waking of the maidens. The hour, 'of night's black arch the keystone,' suggests the unexpectedness of His coming; the loudness of the cry, its all-awaking effect; the broken words of the true reading, 'Behold the bridegroom!' the closeness on the heels of the heralds with which the procession flashes through the darkness. The virgins had 'gone forth to meet him' at the beginning of the parable, but the going forth to which they are now summoned is not the same. The Christian soul goes forth once when, at the beginning of its Christian life, it forsakes the world to wait for and on Christ, and again, when it leaves the world to pass with Him into the banquet. Life is the slumber from which some are awaked by the voice of death, and some who 'remain' shall be awaked by the trumpet of judgment. There is no interval between the cry and the appearance of the bridegroom; only a moment to rouse themselves, to look to their lamps, and to speak the hurried words of the foolish and the answer of the wise, and then the procession is upon them. It is all done as in a flash, 'in a moment, in the twinkling of an eye.' This impression of swiftness, which leaves no time for delayed preparation, is the uniform impression conveyed by all the Scripture references to the coming of the Lord. The swoop of the eagle, the fierce blaze of lightning from one side of the sky to the other, the bursting of the flood, that morning's work at Sodom, not begun till dawn and finished before the 'sun was risen on the earth,' are its types. Foolish indeed to postpone preparation till that moment when cry and coming are simultaneous, like lightning and thunder right overhead!
The foolish virgins' imploring request and its answer are not to be pressed, as if they meant more than to set forth the hopelessness of then attempting to procure the wanting oil, and especially the hopelessness of attempting to get it from one's fellows. There is a world of suppressed terror and surprise in that cry, 'Our lamps are going out.' Note that they burned till the bridegroom came, and then, like the magic lamps in old legends, at his approach shivered into darkness. Is not that true of the formal, outward religion, which survives everything but contact with His all-seeing eye and perfect judgment? These foolish maidens were as much astonished as alarmed at seeing their lights flicker down to extinction; and it is possible for professing Christians to live a lifetime, and never to be found out either by themselves or by anybody else. But if there has been no oil in the lamp, it will be quenched when He appears. The atmosphere that surrounds His throne acts like oxygen on the oil-fed flame, and like carbonic acid gas on the other.
