Mark 9:49

Salted with fire. Concerning salt as a preserving agent see on Matt. 5:13. Fire may be considered as a purifying agent, or as a symbol of the final judgment (see on Matt. 3:10). The meaning of this cryptic statement is not entirely clear, and depends entirely upon the immediate context for a satisfactory explanation. To be “salted with fire” probably means that “every one” will pass through the fires of affliction and purification in this present life (see on Job 23:10) or through the fires of the last day. Fire either removes the dross from this present life or destroys the life itself on the last great day. Salt preserves what is good (see on Mark 9:50).

Every sacrifice. In the ancient sanctuary service salt was added to every sacrifice (see on Lev. 2:13). Its presence signified that only the righteousness of Christ could make the offering acceptable to God (cf. DA 439).
