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,
and the fire is not quenched.’[c]
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.”
New International Version (NIV)
