ISB ~ Mark 9 v49

salted with fire:Probably a reference to the trials and temptations that face believers. Given the preceding context (9:42-48), it may include the purifying suffering of penance needed to avoid sin and turn away from impure habits. Such fire is meant to test the genuineness of our Christian commitment and lead us to perfection (Sir 2:5; 1 Pet 1:6-7; CCC 1430-31). In the end, those refined by the temporal fires of this world will be spared the unquenchable fires of the next.
