Be single-minded and focused upon things of God.
Regard not them that have familiar spirits, neither seek after wizards, to be defiled by them: I am the LORD your God. (Leviticus 19:31 KJV)
The occult comes in many flavors: astrology, spiritualism, magic, and the like. Belief sets which practice a form of divination entertain dark spirits coming straight from the god of this world. There are many belief systems based upon divination including Wicca, Gnosticism, Satanism, and other ritualistic pagan religions.
God plainly and simply says “Regard not them that have familiar spirits…”having no mental or spiritual connection whatsoever with the occult. Occult beliefs and practices are forbidden both in Old Testament times and today. God is a God of light and familiar dark spirits are operating in opposition to the things of God being controlled by the dark spirit world. A person cannot “flirt” or “dabble” with spirits of darkness in any spiritually safe manner. They are dangerous evil spirits and doctrines of the devil. Trying to blend them together while at the same time professing a belief in the truths of God is like mixing oil and water or embarking upon a crooked pathway to spiritual suicide rather than an eternity with God.
