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, into the fire that will never be quenched— ‘where their worm doesn’t die, and the fire is not quenched.’ If your eye causes you to stumble, throw it out. It is better for you to enter into God’s Kingdom with one eye, rather than having two eyes to be cast into the Gehenna of fire, ‘where their worm doesn’t die, and the fire is not quenched.’ For everyone will be salted with fire, and every sacrifice will be seasoned with salt. Salt is good, but if the salt has lost its saltiness, with what will you season it? Have salt in yourselves, and be at peace with one another.

Referring to

Isaiah @isaiah · Isaiah 66:22-24

“For as the new heavens and the new earth, which I will make, shall remain before me,” says the LORD, “so your offspring and your name shall remain. It shall happen that from one new moon to another, and from one Sabbath to another, all flesh will come to worship before me,” says the LORD. “They will go out, and look at the dead bodies of the men who have transgressed against me; for their worm will not die, nor will their fire be quenched, and they will be loathsome to all mankind.”
