This is a great question. Thank you for the privelage to answer such a question!
When I meet God I would share all of the wonderful experiences that I have had within God's creation and thank God for the privelage to live life here on Earth and abroad and to have had all of the experiences that I had which led me back to God.
I would ask God only one question, Can you teach me how to be more like you?
To Love without conditions and to be a peaceful, loving, caring parent to my children like God is to us. For we are all God's children.
