Before Creation

Having read your book “How to know God” i found it interesting the extract where Dame Julian(pg 5) asks God why he created the world and God says that he created it out of love- I understand that but I would like to know, God having created the world out of love where do you think God himself comes from. The Bible doesn’t touch on it, Genesis begins with ‘In the beginning, God created the heavens…’ but what was happening before that?
