Have you ever played with someone who only wants to start fights, who calls everyone names and never wants to follow the rules? The Bible calls that person "the mocker." It's as if they were stepping onto the clean rug of playtime with shoes covered in mud!
The Bible says that sometimes the only way for playtime to become fun again and the fights to end is by saying: "I'm not going to play with you while you act like that." That's not being mean; it's protecting your heart.
Our Father in Heaven wants us to love everyone, but we don't need to walk hand in hand with someone who only wants to make a mess and hurt others.
