I think the problem is that people don't know how to properly distinguish between Law and Gospel and when to use the two. I've been using Law/Gospel with my daughter since she was little. When she was defiant, she got Law, but it wasn't ever me saying she was going to hell for bad behavior. It's not our bad behavior that actually sends us to hell. It's rejection of Jesus. Bad behavior CAN be rejection of Him but it's not an automatic You're going to hell because you brought mud into the house. When my daughter felt bad for dragging mud into the house then I showed her forgiveness which is based on God's forgiveness of us. God uses repentance to turn us from sin and to Him in faith.
