Anyone who belongs to Christ is a new person!
The dictionary defines magic as the practice of using charms, spells, or rituals to attempt to produce supernatural effects or control events in nature.
This includes: horoscopes, astrology, superstitions, witchcraft, or any system claiming use or knowledge of secret or supernatural powers or agencies.
The bible says, "Let no one be found among you who sacrifices his son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead. Anyone who does these things is detestable to the LORD, and because of these detestable practices the LORD your God will drive out those nations before you. You must be blameless before the LORD your God." (Deuteronomy 18:9-13)
Anyone who believes in the magic arts will not be blameless before God. God cannot overlook these acts, for they are wicked. "He sacrificed his own son in the fire, practiced sorcery and divination, and consulted mediums and spiritists. He did much evil in the eyes of the LORD, provoking him to anger." (2 Kings 21:6)
When people practice magic arts, they are doing evil in the sight of God. When you do evil, you provoke God to anger and He will pour out his wrath on you. You will not be blessed, but you will be cursed.
All who practice magic arts will go to the lake of fire (HELL). This is what the bible calls the second death. God will judge all the wicked on Judgment Day.
If you practice magic arts, you need to repent and turn from your wickedness. Then, God will forgive you.
