I would point out, however, that there is no difference between going to a fortune teller and reading your horoscope. Both give you the same knowledge - something about your future. The Bible teaches us that we should trust in God for our future and not seek to find it out by other means. The reason for this command is that he knows how the devil can manipulate our lives. Turning to an astrologer for the future is, in my opinion, akin to putting your trust in a complete stranger who tells you to do something.
Astrologers have no way of knowing the exact future.
God can reveal our future to us, if he so chooses. For him this is not a problem because he is outside the reality of time and space as we understand it. If you still believe astrology is a worthwhile practice then read the following quotes from a recent article in The Daily Telegraph in which Jeannette Kupfermann obtained the following quotes. I know of many who rule their lives by it and wouldn't do anything without consulting their astrologer. It plays to the most vulnerable and fatalistic.
