Mark 9:38-42

John spoke up and said, “Teacher, we noticed someone was using your name to cast out demons, so we tried to stop him because he wasn’t one of our group.” “Don’t stop him!” Jesus replied. “For the one who does miracles in the power of my name proves he is not my enemy. And whoever is not against us is for us. Listen to the truth that I speak: Whoever gives you a cup of water because you carry the name of Christ will never lose his reward. But if anyone abuses one of these little ones who believe in me, it would be better for him to have a heavy boulder tied around his neck and be thrown into the sea than to face the punishment he deserves!
