Then Jesus said, "I tell you the truth. You must change and become like little children {in your hearts}. If you don't do this, you will never enter the kingdom of heaven.
"If one of these little children believes in me, and another person causes that child to sin, then it will be very bad for that person. It would be better for that person to have a millstone F251 tied around his neck and be drowned in the deep sea.
I feel sorry for the people in the world because of the things that make people sin. Those things must happen. But it will be very bad for the person that causes those things to happen.
