Mark 9:38-50 The Message (MSG)
38 John spoke up, “Teacher, we saw a man using your name to expel demons and we stopped him because he wasn’t in our group.”
39-41 Jesus wasn’t pleased. “Don’t stop him. No one can use my name to do something good and powerful, and in the next breath cut me down. If he’s not an enemy, he’s an ally. Why, anyone by just giving you a cup of water in my name is on our side. Count on it that God will notice.
42 “On the other hand, if you give one of these simple, childlike believers a hard time, bullying or taking advantage of their simple trust, you’ll soon wish you hadn’t. You’d be better off dropped in the middle of the lake with a millstone around your neck.
43-48 “If your hand or your foot gets in God’s way, chop it off and throw it away. You’re better off maimed or lame and alive than the proud owner of two hands and two feet, godless in a furnace of eternal fire. And if your eye distracts you from God, pull it out and throw it away. You’re better off one-eyed and alive than exercising your twenty-twenty vision from inside the fire of hell.
49-50 “Everyone’s going through a refining fire sooner or later, but you’ll be well-preserved, protected from the eternal flames. Be preservatives yourselves. Preserve the peace.”
Mark 9:38-50 New International Version (NIV)
Whoever Is Not Against Us Is for Us
38 “Teacher,” said John, “we saw someone driving out demons in your name and we told him to stop, because he was not one of us.”
39 “Do not stop him,” Jesus said. “For no one who does a miracle in my name can in the next moment say anything bad about me, 40 for whoever is not against us is for us. 41 Truly I tell you, anyone who gives you a cup of water in my name because you belong to the Messiah will certainly not lose their reward.
Causing to Stumble
42 “If anyone causes one of these little ones—those who believe in me—to stumble, it would be better for them if a large millstone were hung around their neck and they were thrown into the sea. 43 If your hand causes you to stumble, cut it off. It is better for you to enter life maimed than with two hands to go into hell, where the fire never goes out.  [a] 45 And if your foot causes you to stumble, cut it off. It is better for you to enter life crippled than to have two feet and be thrown into hell.  [b] 47 And if your eye causes you to stumble, pluck it out. It is better for you to enter the kingdom of God with one eye than to have two eyes and be thrown into hell, 48 where
“‘the worms that eat them do not die,
49 Everyone will be salted with fire.
50 “Salt is good, but if it loses its saltiness, how can you make it salty again? Have salt among yourselves, and be at peace with each other.”
Mark 9:38-50 King James Version (KJV)
38 And John answered him, saying, Master, we saw one casting out devils in thy name, and he followeth not us: and we forbad him, because he followeth not us.
39 But Jesus said, Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me.
40 For he that is not against us is on our part.
41 For whosoever shall give you a cup of water to drink in my name, because ye belong to Christ, verily I say unto you, he shall not lose his reward.
42 And whosoever shall offend one of these little ones that believe in me, it is better for him that a millstone were hanged about his neck, and he were cast into the sea.
43 And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched:
44 Where their worm dieth not, and the fire is not quenched.
45 And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feet to be cast into hell, into the fire that never shall be quenched:
46 Where their worm dieth not, and the fire is not quenched.
47 And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire:
48 Where their worm dieth not, and the fire is not quenched.
49 For every one shall be salted with fire, and every sacrifice shall be salted with salt.
50 Salt is good: but if the salt have lost his saltness, wherewith will ye season it? Have salt in yourselves, and have peace one with another.
