Charles H. Spurgeon on Psalms 55:15

Let death seize upon them by divine warrant, and let them go quick into hell; let them be dead and buried, and damned in a moment; for wickedness is wherever they are, it is in the midst of them. The souls of impenitent sinners go down quick, or alive, into hell; for they have a perfect sense of their miseries, and shall therefore live still, that they may be still miserable. This prayer is a prophecy of the utter, the final, the everlasting ruin of all those who, whether secretly or openly, oppose and rebel against the Lord's Messiah. Matthew Henry.
