42 Whoever will cause one of these little ones who believe in me to stumble, it would be better for him if he was thrown into the sea with a millstone hung around his neck. 43 If your hand causes you to stumble, cut it off. It is better for you to enter into life maimed, rather than having your two hands to go into Gehenna, [1] into the unquenchable fire, 44 ‘where their worm doesn’t die, and the fire is not quenched.’ 45 If your foot causes you to stumble, cut it off. It is better for you to enter into life lame, rather than having your two feet to be cast into Gehenna, [2] into the fire that will never be quenched— 46 ‘where their worm doesn’t die, and the fire is not quenched.’ 47 If your eye causes you to stumble, cast it out. It is better for you to enter into the Kingdom of God with one eye, rather than having two eyes to be cast into the Gehenna [3] of fire, 48 ‘where their worm doesn’t die, and the fire is not quenched.’ [4]
Matthew Henry's Commentary on Mark 9:42-48
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.
