Parents cannot buy affection from the child. A child will resent the parent who makes them eat properly. The child will love us in the long run but probably not the short run if we execute discipline. If we do not do what is right for them, they may not love us, or at least not respect us, in the short run. Disobedient children are the cause of much of the strife and division in the home.
Some teens become very rebellious in their late teens.
When children leave their home then they establish a new home and authority. Without divine institution there is no freedom. There is no freedom without principles. To maintain freedom we need law. If there is no traffic light there is no freedom to drive with safety.
