Again, this event is a prophecy. So our Lord has employed it; and much of the imagery in which the last judgment is represented is directly drawn from this narrative. So far from this story showing to us only the superstitions of a form of belief which we have long outgrown, its deepest meaning lies far ahead, and closes the history of man on the earth. We know from the lips which cannot lie, that the appalling suddenness of that destruction foreshadows the swiftness of the coming of that last 'day of the Lord.' We know that in literality some of the physical features shall be reproduced; for the fire which shall burn up the world and all its works is no figure, nor is it proclaimed only by such non-authoritative voices as those of Jesus and His apostles, but also by the modern possessors of infallible certitude, the men of science. We know that that day shall be a day of retribution. We know, too, that the crime of Sodom, foul and unnatural as it was, is not the darkest, but that its inhabitants (who have to face that judgment too) will find their doom more tolerable, and their sins lighter, than some who have had high places in the Church, than the Pharisees and wise men who have not taken Christ for their Saviour.
4. The fate of the loiterer. Her backward look must have been more than momentary, for the destruction of the cities did not begin till Lot was safe in Zoar. She must have lingered far behind, and been overtaken by the eruption of liquid saline mud, which, as Sir J. W. Dawson has shown, would attend or follow the outburst of bituminous matter, so that her fate was the natural consequence of her heart being still in Sodom. As to the 'pillar of salt' which has excited cavils on the one hand and foolish legends on the other, probably we are to think rather of a heap than of a pillar. The word does not occur in either meaning elsewhere, but its derivation implies something raised above the level of the ground; and a heap, such as would be formed by a human body encrusted with salt mud, would suit the requirements of the expression. Like a man who falls in a snowstorm, or, still more accurately, just as some of the victims at Pompeii stumbled in their flight, and were buried under the ashes, which still keep the outline of their figures, so Lot's wife was covered with the half-liquid slimy mud. Granted the delay in her flight, the rest is perfectly simple and natural. She was buried in a horrible tomb; and, in pity to her memory, no name has been written upon it. She remains to all generations, in a far truer sense than superstition dreamed of when it pointed to an upright salt rock as her prison and her monument, a warning of the danger of the backward look, which betrays the true home of the heart, and may leave us unsheltered in the open plain when the fiery storm bursts. 'Remember Lot's wife.'
When the angels awoke Lot, the day was breaking. By the time that Abraham had risen 'early in the morning,' and reached the place by his tent from which he had yesterday looked on the smiling plain, all was over, and the heavy smoke cloud wrapped the dead with its pall-like folds. So swift and sudden is to be the coming of the Son of man,--as the lightning which rushes in one fierce blinding flash from one side of heaven to the other. Wherefore, God calls to each of us: 'Escape for thy life; look not behind thee.'
