This is the counsel which the prophet gives his fellow-countrymen, in view of the desolations which God was about to send upon their land on account of their sins. He sees God's judgments sweeping down upon them like an invading army, and therefore he cries to them, "Flee into the caverns in the mountains:" like the _Simoom,_ and therefore he cries to them, "Hide yourselves in the dust: bow down before the destroying blast from which it is impossible to escape. God has been silent, as if He were indifferent to your transgressions, but now He is coming forth, in all the terrors of His majesty to require the evil doers according to their works."[1] The counsel is, of course, metaphorical; the rocks and the dust could afford no refuge from an angry God. _The summons is to profound and penitential humility,_ the proper attitude of man to God. It is a summons, therefore, which may be fitly addressed to all men. +I. Profound humility in regard to God would be befitting in us as creatures, even were we absolutely without sin.+ Such humility is reasonable--1. In view of our relation to and dependence upon God. He is our Maker; we are daily pensioners on His bounty; we are the instruments with which He carries out His purposes (ch. x. 15). 2. In view of His position as the Ruler of the universe. 3. In view of the transcendent excellencies of His character. The pupils of a great artist, such as Raphael, the associates of a great patriot, such as Washington, are filled with involuntary admiration and veneration for him. They feel themselves to be as nothing in comparison with him. How much more should we feel so in comparison with God! Those sinless being who see Him as He is show us by their conduct what would be befitting in us even were we also without spot or stain (ch. vi. 2, 3). +II. But as sinners that which is befitting in us is, not only profound, but penitential humility.+ To live without any sense of guilt in our hearts--with indifference to the fact that we have broken God's laws and are exposed to His judgements--is itself a gross iniquity; it is an outrageous defiance of the majesty in whose presence we are. What would be said of a rebel who in the presence of his outraged sovereign should absolutely _ignore_ him? Would not this be regarded as a repetition of his offence in the most aggravated form? But is not this precisely the offence which every stout-hearted sinner daily commits? As sinners there are two things especially incumbent upon us. 1. _To humbly acknowledge that we are exposed to the Divine judgments, and need a refuge therefrom._ There are two ways of contemplating the Day of Judgment: (1) As a certain and solemn fact in the history of our race. Contemplating it thus, we may show argumentatively that such an event ought to occur; and we may anticipate to some extent the principles upon which the Judge, when He shall have summoned mankind before His bar, will proceed. We may do this, and be merely theological or rhetorical.
