42 And whosoever shall cause one of these little ones that believe on me to stumble, it were better for him if a great millstone were hanged about his neck, and he were cast into the sea. 43 And if thy hand cause thee to stumble, cut it off: it is good for thee to enter into life maimed, rather than having thy two hands to go into hell, into the unquenchable fire. 44 [where their worm dieth not, and the fire is not quenched.] 45 And if thy foot cause thee to stumble, cut it off: it is good for thee to enter into life halt, rather than having thy two feet to be cast into hell. 46 [where their worm dieth not, and the fire is not quenched.] 47 And if thine eye cause thee to stumble, cast it out: it is good for thee to enter into the kingdom of God with one eye, rather than having two eyes to be cast into hell; 48 where their worm dieth not, and the fire is not quenched. 49 For every one shall be salted with fire. 50 Salt is good: but if the salt have lost its saltness, wherewith will ye season it? Have salt in yourselves, and be at peace one with another.
Matthew Henry's Commentary on Mark 9:42-50
Commentary on Mark 9:41-50
(Read Mark 9:41-50)
It is repeatedly said of the wicked, Their worm dieth not, as well as, The fire is never quenched. Doubtless, remorse of conscience and keen self-reflection are this never-dying worm. Surely it is beyond compare better to undergo all possible pain, hardship, and self-denial here, and to be happy for ever hereafter, than to enjoy all kinds of worldly pleasure for a season, and to be miserable for ever. Like the sacrifices, we must be salted with salt; our corrupt affections must be subdued and mortified by the Holy Spirit. Those that have the salt of grace, must show they have a living principle of grace in their hearts, which works out corrupt dispositions in the soul that would offend God, or our own consciences.
