Thomas Watson has some sobering thoughts on hell.
“The torments of hell abide for ever. ‘The smoke of their torment ascendeth up for ever and ever.’ Rev. xiv 11. Time cannot finish it, tears cannot quench it. Mark ix 44. The wicked are salamanders, who live in the fire of hell, and are not consumed. After they have lain millions of years in hell, their punishment is as far from ending, as it was at the beginning. If all the earth and sea were sand, and every thousandth year a bird should come, and take away one grain, it would be a long time before that vast heap would be removed; yet, if after all that time the damned might come out of hell, there would be some hope; but this word EVER breaks the heart.”
Thomas Watson, The Ten Commandments, 42.
