Just curious ... if the Judeo CHristian God condemns things such as astrology, then how could it lay out His plan? And why would He use something he condemns, astrology for His plan?
In Judaism there is a path that the world is destined to follow. It is called in Hebrew "Mazal". The word is often used like one would say luck, as in "Mazal Tov" or good luck. The word in the actually scriptual usage that I have studied has to do with divine providence. That is why we pray to G-d. Since G-d created the world's "mazal", he can alter it with our prayers (if he so chooses).
Divine providence is an altogether confusing subject in itself. The bottom line is that G-d wants us to come and ask him for our "good fortune" instead of going to astrologers or seers. It is taught that to put one's trust in anything else is to subject oneself to the mazal of the world that he created.
