I. To startle and awaken secure sinners, who cry peace to themselves, and bid defiance to God and his judgments (v. 10): "Enter into the rock; God will attack you with such terrible judgments, and strike you with such terrible apprehensions of them, that you shall be forced to enter into the rock, and hide yourself in the dust, for fear of the Lord. You shall lose all your courage, and tremble at the shaking of a leaf; your heart shall fail you for fear (Luke xxi. 26), and you shall flee when none pursues," Prov. xxviii. 1. To the same purport, v. 19. They shall go into the holes of the rocks, and into the caves of the earth, the darkest the deepest places; they shall call to the rocks and mountains to fall on them, and rather crush them than not cover them, Hos. x. 8. It was so particularly at the destruction of Jerusalem by the Romans (Luke xxiii. 30) and of the persecuting pagan powers, Rev. vi. 16. And all for fear of the Lord, and of the glory of his majesty, looking upon him then to be a consuming fire and themselves as stubble before him, when he arises to shake terribly the earth, to shake the wicked out of it (Job xxxviii. 13), and to shake all those earthly props and supports with which they have buoyed themselves up, to shake them from under them. Note, 1. With God is terrible majesty, and the glory of it is such as sooner or later will oblige us all to flee before him. 2. Those that will not fear God and flee to him will be forced to fear him and flee from him to a refuge of lies. 3. It is folly for those that are pursued by the wrath of God to think to escape it, and to hide or shelter themselves from it. 4. The things of the earth are things that will be shaken; they are subject to concussions, and hastening towards a dissolution. 5. The shaking of the earth is, and will be, a terrible thing to those who set their affections wholly on things of the earth. 6. It will be in vain to think of finding refuge in the caves of the earth when the earth itself is shaken; there will be no shelter then but in God and in things above.
