Occult means "hidden". It covers practices that are not approved of by God e.g., astrology (Isaiah 47:13), casting spells (Deut. 18:11), consulting with spirits (Deut. 18:11), magic (Gen. 41:8), sorcery (Exodus. 22:18), witchcraft (Deut. 18:10), and spiritism (Deut. 18:11). Concerning occult practices, the Israelites were told: "When you come into the land which the LORD your God is giving you, you shall not learn to follow the abominations of those nations. There shall not be found among you anyone who makes his son or his daughter pass through the fire [an ancient occult practice], or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. For all who do these things are an abomination [detestable] to the LORD..." (Deuteronomy 18:9-12a).
Magic, spells, enchantments, charming, sorcery, wizardry, witchcraft: Research has shown that occult magic is often fraudulent and deceitful illusion—counterfeit miracles. Many books have been written on this subject. In some instances, occult magic or divination are a manifestation of demonic powers or the result of demon possession (Acts 16:16). Of course, the power of Satan and his demons is extremely limited compared to God's power.
Those who follow the path of the magic arts are on the wrong path - a road that leads away from God, not toward Him. In one way or another, the end will be disaster. The evil Queen Jezebel practiced witchcraft (2 Kings 9:22) bringing catastrophe on herself and all Israel. Over and over, God denounces those who "conjure spells" (NKJV) and those who practice witchcraft and sorcery.
