My granddaughter has a friend who is reading his horoscope daily and sees nothing wrong with it. She needs specific verses of scripture to show him that will convince him it is demonic. I am familiar with the verses in Deuteronomy 18, and in several places in Daniel, but they are not as specific as I would like. Can you help?
The phrase “observer of times” in Deut. 18:10 and other places is commonly regarded to mean astrology and is described as being detestable to God. The study of astrology was forbidden in the Old Testament.
You didn’t mention whether the friend is a believer or not, but if he is then knowing something is detestable to God should be sufficient motivation to stop doing it, whether he believes it’s demonic or not.
