And if anyone causes one of these little ones who believe in me to sin, it would be better for him to be thrown into the sea with a large millstone tied around his neck. 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 into hell, where the fire never goes out. And if your foot causes you to sin, cut it off. It is better for you to enter life crippled than to have two feet and be thrown into hell. And 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 to have two eyes and be thrown into hell, where their worm does not die, and the fire is not quenched.
~ Mark 9:42-48, NIV
