42 and whoever may cause to stumble one of the little ones believing in me, better is it for him if a millstone is hanged about his neck, and he hath been cast into the sea. 43 'And if thy hand may cause thee to stumble, cut it off; it is better for thee maimed to enter into the life, than having the two hands, to go away to the gehenna, to the fire—the unquenchable— 44 where there worm is not dying, and the fire is not being quenched. 45 'And if thy foot may cause thee to stumble, cut it off; it is better for thee to enter into the life lame, than having the two feet to be cast to the gehenna, to the fire—the unquenchable— 46 where there worm is not dying, and the fire is not being quenched. 47 And if thine eye may cause thee to stumble, cast it out; it is better for thee one-eyed to enter into the reign of God, than having two eyes, to be cast to the gehenna of the fire— 48 where their worm is not dying, and the fire is not being quenched; 49 for every one with fire shall be salted, and every sacrifice with salt shall be salted. 50 The salt 'is' good, but if the salt may become saltless, in what will ye season 'it'? Have in yourselves salt, and have peace in one 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.
