Ok, I think God is the justification for the "why" there is justification, and the justification for himself, and the meaning for himself. What is the justification of love and morality in your scenario?
As he is the ultimate meaning for himself, he out of his compassion and grace created us to worship him, so that he can bestow upon on his love and grace and make us appreciate ourselves, God and others.
