Cup

41For truly, I say to you, whoever gives you a cup of water to drink because you bear the name of Christ, will by no means lose his reward.  42"Whoever causes one of these little ones who believe in me to sin, it would be better for him if a great millstone were hung round his neck and he were thrown into the sea.  43And if your hand causes you to sin, cut it off; it is better for you to enter life maimed than with two hands to go to hell, to the unquenchable fire.  45And if your foot causes you to sin, cut it off; it is better for you to enter life lame than with two feet to be thrown into hell.  47And if your eye causes you to sin, pluck it out; it is better for you to enter the kingdom of God with one eye than with two eyes to be thrown into hell,  48where their worm does not die, and the fire is not quenched.  49For every one will be salted with fire.  50Salt is good; but if the salt has lost its saltness, how will you season it? Have salt in yourselves, and be at peace with one another." Mark 9:41-50
