Roxy, if I asked that question, it would be like this. Why don't you MEN behave like God if you were created like him. Why do you behave so crummy? I would myself that question too.
God the Father. God the Son. God the Holy Spirit. The three are one...they are in a relationship with each other to the point of being one.
We were created to be in a relationship with Him and with each other rooted in genuine love. It is when we operate outside of that kind of a relationship that things fall apart.
