Proverbs 6:28

Can one go upon hot coals, and his feet not be burned?] He cannot; if he sets his feet upon them, and continues them ever so little on them, they will be burnt, and much more if he walks upon them; and so if a man gives way to the burning lusts of his heart after a whorish woman, and commits adultery with her, though not with frequency, he will not escape punishment in one shape or another; and much more if he continues such a lewd course of life; such practices are extremely dangerous q, and there is no possibility of being unhurt by them: see Job 31:12; the lake of fire and brimstone, everlasting burnings, will be the portion of those that commit fornication with the whore of Rome, Revelation 14:10.
