magic is a lie?

Demons?? ROFLMMFAO!! Please... Practicing most forms of magic do not summon demons. Demons just simply can't be bothered with you humans to be quite honest - they have more fun and important things to do. Unless someone has done something really wrong and has created a major offense, you will NEVER see a demon in your lifetime.

Now intentionally summoning them - that's a horse of a different colour. Using necromancy - the true necromantic arts, will garner attention thrown in your attention but usually from a different group and not the demonic hordes :) But unless you have a license to practice this art, stay away from it. The same can be said about demon summoning. Unless you have an intimate connection with them, and you will know if you do or not, don't bother them. They're like the angels in the respect that they really don't like to be bothered unless it's really important. And if you have it in your tiny brain to think that, "oh, it's an angel, I can summon them, they're of the 'light' they're good..." Think again. They'll smite your ass just as fast as a demon will for bothering them for nonsense.

Children today thinking they can just play around with forces that have existed long before your species has walked this planet. That have existed before the concept of time and space existed. Sigh...

Your pastor is wrong in so many ways, and the previous posters have covered the subject extensively with great replies.

Magic is not a lie.
