The difference with HP is that it makes the occult into something that is neutral - it is only good or evil depending on your motives. This is the lie that is packaged in HP.
God’s Word does speak of witches. The Old Testament was clear about avoiding the occult. Part of the reason was God said to avoid it. The practical implications is that fallen angels (demons) who still have certain powers and abilities (for now) are the sources of the things that are occultic.
Spend a little time in the Bible reading up on what God says about things occult:
Do not pass your children through the fire (child sacrifice). Do not practice divination (see the future) or sorcery. Do not turn to mediums (who can speak/conjure the dead)or seek out spiritists, for you will be defiled by them. A man or woman who is a medium or spiritist (aka wizard) among you must be put to death.
I take it you haven't read them either?
There is a clear distinction between good and evil in HP. Yes, some of the "spells" are used by both sides. At the same time there are "unforgiveable" curses that are clearly evil.
And there are always consequences for your behavior.
Well then, I guess C.S. Lewis was a heathen. Read The Lion, The Witch and The Wardrobe again. The Witch and Aslan both practice "the Deep Magic, but one does so for good and the other evil.
“A man or woman who is a medium or spiritist (aka wizard) among you must be put to death.”
Mixed message. Killing a wizard would go against the commandant, “Thou should not murder”.
I don't do any of those things, but I enjoy reading Harry Potter stories, and so do my kids.
YOU read about them in the Bible, does that make you want to DO any of them?
