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.
There are two categories of sin: sins against God and sins against man. By default, every sin is against God. Yet, not all sin is against man.
Sin is not something man does by accident. It is something man does or allows based upon an unwillingness to stop an act before it becomes sin.
