Those who meddle with astrologers and sorcerers (and like practices) put themselves on a collision course with God's judgment.
Many unsaved people practice astrology (i.e., horoscopes) and other unscriptural use of the signs in the heavens. Believers should reject these practices.
In every way, God is greater than man. A man would have to be a thief to claim equality with God. Yet, Christ thought it not robbery to be equal with God.
