I wouldn't care if astrology or magicians or anything else of this nature was right 100% of the time, it still does not make it something that God wants us to have anything to do with!
I was into all this New Age Nonsense before I got saved, and believe me, it was not right, or good or anything else. My suggestion is to stay away from it.
When I was taking a course for transfer credit in a local seminary, there was a native woman, who had a lot to say against native spirituality. One day someone mentioned "Ouija boards" in the class, and she replied that it was a "portal to evil."
I could not agree more! Those things drag people away from Christ and into the devil's clutches. That is what happened to me. I started with astrology when I was 12, moved onto Ouija boards, reincarnation, and soon moved to a full fledged devotee of the New Age movement.
Definitely not something to play around with, nor think that it comes from God! And Satan can do evil things with people who follow him - do not ever forget that for a moment!
