Charles H. Spurgeon on Psalms 46:2

Therefore. How fond the psalmist is of therefores! his poetry is no poetic rapture without reason, it is as logical as a mathematical demonstration. The next words are a necessary inference from these. Will not we fear. With God on our side, how irrational would fear be! Where he is all power is, and all love, why therefore should we quail? Though the earth be removed, though the basis of all visible things should be so convulsed as to be entirely changed. And though the mountains be carried into the middle of the sea; though the firmest of created objects should fall to headlong ruin, and be submerged in utter destruction. The two phrases set forth the most terrible commotions within the range of imagination, and include the overthrow of dynasties, the destruction of nations, the ruin of families, the persecutions of the church, the reign of heresy, and whatever else may at any time try the faith of believers. Let the worst come to the worst, the child of God should never give way to mistrust; since God remaineth faithful there can be no danger to his cause or people. When the elements shall melt with fervent heat, and the heavens and the earth shall pass away in the last general conflagration, we shall serenely behold "the wreck of matter, and the crash of worlds, "for even then our refuge shall preserve us from all evil, our strength shall prepare us for all good.
