You know that whenever I can come up with a useful analogy or example I try to share them here on my blog. I put them out as a quick "dose" of perspective, rather than covering the whole subject again, or go into length as I have in the archives. Here's one about astrology and why it is a falsehood and forbidden.
Suppose you had in the 1990's a teenager who is thinking about what career he would like to pursue. An astrologer (especially a meddling parent or aunt) would think she or he is "helping" by studying the teenager's chart to try to discern the future. But while doing so, obviously the astrologer can only think of scenarios that are part of her or his day to day reality. For example the astrologer would look to see if the teenager would be "in the public" or "communications oriented" and "where the money would originate." But God, through free will and openness of heart, has a smorgasbord of possibilities available to each person that neither a so called tool such as astrology or the user of the tool, the human, can predict or even consider or be aware of at all. Suppose the astrologer "guides" the teenager toward a media career because she can "see" that he would "do well" financially and "personal satisfaction" through such a career choice. If the teenager listens to this advice (or is forced to follow because the parents will only pay for certain college choices) he now orients his day to day lifestyle toward that choice. But here is what might have happened had astrology not intruded. The teenager might have picked up a book about Afghanistan, or met someone from the Sudan. The teenager might have had a chat or read that had a profound effect on him, and decided to become a microbiologist who speaks Arabic. I mean, who could look at a stupid so called astrology chart and say, "Hey Fred, if you decide to learn Arabic and go into research medicine, in twenty years you can help build a hospital in war torn Afghanistan!" You can't begin to see the myriad of beautiful choices that life brings in subtle ways through inspiration, conversations, openness to the Holy Spirit, and day to day living by looking at a stupid false chart from within your bourgeoisie Chinese take out mind of choices based on your limited reality. So this meddling "astrologer" guides the teenager to be an Internet programmer, ad executive, or whatever, while "God's plan" would have been that this teenager be inspired by a chat or a book and find himself to be trained for a need that no one even knew would exist at the time, a microbiologist who also cares about a society that had not received much attention but would become a flashpoint of need. This is why astrology is strictly forbidden and works directly antagonistic to God's will for the goodness of all people.
