Mark 9:49

every one shall be salted with fire Salt and fire have properties in common. Salt, like a subtle flame, penetrates all that is corruptible, and separates that which is decaying and foul, whilst it fixes and quickens that which is sound. Fire destroys that which is perishable, and thereby establishes the imperishable in its purest perfection, and leads to new and more beautiful forms of being. Thus both effect a kind of transformation. Now "every one," our Lord saith, "shall be salted with fire;" either (1) by his voluntary entering upon a course of self-denial and renunciation of his sins, and so submitting to the purifying fire of self-transformation; or (2) by his being involuntarily salted with the fire of condemning judgment (Hebrews 10:27; Hebrews 12:29), as the victims on the altar were salted with salt (Leviticus 2:13; Ezekiel 43:24).
