Mark 9:42-43

42A person who believes in me may not seem important. But you should never make that person do wrong things. Do not do that! It would be better if someone tied a big stone around your neck and then he threw you into the sea!

43If your hand causes you to do wrong things, you should cut it off. You will only have one hand, but you can have God's true life. It will be much worse for you if you keep both your hands and go to hell. There, the fire always burns and never stops.
