It's up to you whether it is against God or not, we all have seperate beliefs. At a young age, most of us are taught that thers is one right answer to life and all it's wondrous mysteries, good is good, evil is evil, God is supreme, and nothing else exists. Black and white are what we see in our infancy, then the colors red and yellow come to us, and unveil different perspectives on spirituality and the reasons for our existence, it's purely what you believe, and what path your intuition leads.
If you truly think magick is immoral, don't practice it until you come to peace with it yourself. Logic, it's a great gift, utilize it :)
Good luck on your spiritual journeys Ashley, don't be afraid to email me on questions of morality, gods and the sort.
