Hmmm... the way that statement is phrased makes God sound like a rampant egotist. I believe (well most of the time when away from plaguing negative thoughts & doubts) that we live in a great big fancy physical creation that remains bound to God and has underlying laws that underpin everything that lives and breathes and certainly help to keep things ticking along nicely. These laws when followed assist us all to live together and have a great time. Pull away from these laws and we suffer as a whole ... the plants, the animals, the humans, the whole creative heap starts to go down. So if we remain bound to God, things go well etc etc That could be just the way it is - why not?
The expression of evil in my opinion is rooted in selfishness and the chosen tool of the short-sighted to help define their reality and provide short cuts and easy answers to deep-rooted fears and frustrations. Evil may also be the expression of a bloated ego.
Those with real vision embrace the whole picture and work towards the deeper principle of love; namely self-sacrifice.
