At the risk of over simplifying, you need to know that God is Good and only wants to do you good; the Devil is bad and only wants to do you bad. If God tells you to stay away from something it is because it will destroy you, not because he doesn't want you to enjoy your life. Jn. 10:10 "The Thief (Satan) came to steal, kill and destroy but Jesus came to give you life and life more abundantly."
Don't fall for the games the Devil plays! An onslaught of sorcery, bewitching, enchantments, spells, Voodoo, Ouija boards, seances, crystals, tarot cards, crystal balls, astrology, Teraphim (household good luck images), etc., has been unleashed upon our land in the name of Entertainment, Religion and especially Halloween. Part of the deception is that it is "harmless" or it is "not real." Satan and His demonic assignments are real. You may have meant it all in "good fun" but the Devil is serious and plays for keeps. He does not care if it was just something you did at some party. 1 Pet. 5:8 "Be sober, be vigilant because your adversary (Devil) walks about like a roaring lion, seeking whom He may devour." He wants to gain entry into your life. If you give him an Inch he will be your Ruler. Do not give him a platform to operate from in your life. He specializes in Fear & Terror. He especially likes to attack little children who innocently watch cartoons and movies and play video games that are laced with fear, violence and witchcraft. It seems that witchcraft and all that it entails is in "vogue" right now. Be careful and mindful of what you and your children watch and participate in.
Deut. 18:9-11 "When you come into the land which the Lord your God is giving you, you shall not learn to follow the abominations (detestable acts) of those nations. There shall not be found among you anyone who makes his son or daughter PASS THROUGH THE FIRE, 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."
1 Sam. 15:23 "For rebellion is as the sin of witchcraft and stubbornness is as iniquity and idolatry."
There is only One true God, the God of the Holy Bible. He is the One worthy of your worship and devotion. He is the God of power and might. Satan offers a counterfeit power and direction. He wants your worship and devotion. Look only to the Lord to direct you and guide you. The Holy Spirit will be your indwelling Teacher.
Some who have been lured into Satan's trap have experienced demonic manifestations and don't know what to do. Remember Isa. 61:1 declares-He came to set the captives free; Jn 8:32 -You shall know the truth and the truth shall make you free; 2 Tim. 1: 7-God has not given us a spirit of fear, but of power and of love and of a sound mind; 1 Jn. 4:4-Greater is He (God) that is in you than he (Satan) that is in the world.
Know that God loves you! Jer. 29:11 states, "For I know the thoughts that I think toward you, says the Lord, thoughts of peace and not of evil, to give you a future and a hope." Call out to the Lord Who loves you with an unfailing love. Confess your SIN (an archery term that means to miss the mark, failure, taking the wrong course). REPENT (change your mind & turn away from the sin). RENOUNCE (declare you will no longer engage in the activity) your sin.
Guard your heart, your eye gate, your ear gate and your mind. Read the Holy Bible. Fellowship with the Lord through prayer and worship. Faithfully attend a Bible believing, alive church!
Psa. 34:8 "TASTE AND SEE THAT THE LORD IS GOOD!" ENJOY the presence of the Lord and your life!
