Bad parenting and no God in home or school - that’s it in a nutshell.
This is the reason there is so much “mental illness”, leading to the use of so many drugs.
If you think of every problem our society has, following the teachings of Scriptures will rectify it, or at the very least give us instruction on dealing with it.
YOU are right. The lack of love (God), and attention at home has much to do with why children/teens do what they do.
As a former CJ Instructor, let me say this, there was a study done in Juvenile Detention Centers, with surveys on why those young people ended up there. One thing stood out, most felt no one would care if they were gone, and incarcerated. There was NOT one relationship...parent, grandparent, older sibling, or even community, that they felt close enough to, that would cause them to think about NOT doing the crime. Sad.
AS families we can miss the ability to connect with children or teens, because we do not realize how important their need for love really is, and making the effort to get close to them is usually abandoned; if they are too much trouble or their attitude offends us. Usually, there is a reason for their anger, attitude, or actions. Finding out what that is will not only help them stay out of system, but teach us that inside... there is a pain they would love to share, but can’t, unless there is close relationship that is safe!
