When the Ephesians believed on Christ, they examined the moral nature of each aspect of their lives. This led them to burn their curious arts books.
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.
Men not only develop reputations among other men, but they also develop a reputation with the Lord. A wise individual seeks “favour and good understanding in the sight of God and man.” Fortunately, the path to favour in the sight of God follows the same course as that of finding favour in the sight of the right kind of men. According to Proverbs 3:1-3, these elements include remembrance of God’s law, keeping the commandments, and forsaking not mercy and truth. Before dismissing the importance of this dual favour amongst both God and man, consider that the scriptures inform us that the Lord Jesus increased in wisdom leading to an increase in “favour with God and man.”
