God punishing his children

Have you heard that God punishes us to prevent our being bad or doing stupid things and getting hurt. In this he shows his love for us. 

Psychologists know that if one tries to use punishment to teach a kid right and wrong, what you really do is teach the kid to lie and cause resentment and, depending on the severity, even hate. There are much better ways to raise kids.

Also, delayed consequences don't teach either. "Just wait until your father gets home," teaches the kid nothing about right and wrong and only that the father is someone to be feared.

There are ways, using real love and real compassion, to raise good children and never engage in any sort of punishment, neither physical nor verbal nor via denials. There are many books on the subject so I won't try to demonstrate this here.

Yet isn't the method known to be wrong the way the churches tell us God behaves?
