The early church used to have as part of the baptismal formula "I renounce all the works of the Devil" and those becoming Christians were required to destroy any idols or charms or magic books that they owned (see Acts 19:19 above for an example). Because the sins of idolatry, witchcraft, and involvement in magic or the occult are "abominations" that is very offensive to God - then they must be confessed and sometimes using a prayer for spiritual cleansing can be a big help. Here is a procedure for dealing with any occult involvement.
1. Do a personal inventory of both your involvement and your families involvement in the occult - could your grandmother tell fortunes, did you have an uncle who was a magician (not tricks - real magic), were your parents members of an organisation like "The Spiritualist Church". remember the punishment for these sins goes down the generations and could be affecting you. Confess all these that you know of to God and ask His forgiveness.
2. Burn everything that is associated with the occult -jade Buddhas, temple wind chimes, tarot cards, magic books, demon masks, even the "dark" kind of heavy metal music, things with pentagrams on it (the five pointed occult star), astrology books, love magic , charms, books from cults such as the JW's or Mormons, when in doubt destroy it. Many people are trapped by the value of these items as they can be covered with gold or silver or be "old and rare books" etc. The Ephesian Christians burnt 50,000 drachmas (about 5 million dollars worth) of magic books when they became converted. The Bible tells us (Deut 7:25) that we are not to covet the silver or the gold that is on them - its tempting but its dangerous.
3. Set yourself a program of bible reading and prayer and ask God to renew you spiritually and be Lord of your life. (John 3:1-17)
4. Ask God to fill you with the Holy Spirit so you can know the true spiritual power that is from God and serve Him.
Curses are an unusual topic, but they are real, you can even buy numerous books on how to curse people in most bookstores especially New Age bookstores. They are now part of "teenage witch" type TV programs. However curses are not playthings and are profoundly emotionally disturbing for those who experience them. They are not just angry words or swear words; they are acts of power in the spiritual realm. Curses are mentioned over 200 times in Scripture, and were foundational to the Old Covenant (see Deuteronomy 28-30). God Himself was the first one to pronounce curses – on the earth, on Eve’s fertility and upon the serpent. Curses are not just a primitive superstition; they are spiritual pronouncements recorded in Scripture, that profoundly affect the very structure of reality in some way.
Curses And Creation
The world was created by the word of God and is held together by the power of His Word (Genesis 1, Hebrews 1:1-3, Colossians 1:17-20). Thus God’s words can change creation and Jesus’ curse caused the fig-tree, representing barren Israel, to shrivel up. Blessings and curses are first of all God’s words that operate at this fundamental level of creation and “tilt the playing field” of life one way or another. Secondly curses and blessings can be from evil spirits or flow from the human spirit. Goliath's curses against David were “by his gods” (1 Samuel 17:43) and were ineffective for reasons we shall see later. The David and Goliath encounter was a power encounter of one spiritual system against the other and both contenders came in the name of their respective deities. Shamans and magicians such as Balaam were hired to curse people in OT times and still do this today. Though curses from evil sources much less powerful than curses from God they still were feared and were able to do much damage. There are 22 references exhorting believers not to curse others. Curses are finally ended in the new creation (Rev 22:3).
The origin of blessings and curses is found in the book of Genesis. The first blessing is upon the living creatures, which were told to “be fruitful and multiply” (Genesis 1:22). When God made mankind He also blessed them saying “be fruitful and multiply” and added a third blessing “have dominion over” (Genesis 1:28). These three basic blessings of: “be fruitful”, “multiply” and “have dominion over” form the basis of all future blessings, such as the Abrahamic blessings, and their reversal forms the basis of all future curses such as those in Genesis 3. Lets look at this a little bit further:
Fruitfulness is the ability to joyfully express your inner nature and feel that which you are doing is truly creative, worthwhile and significant. Its opposite is pain in creation especially barrenness.
Multiplication is exponential increase - increasing as in 2, 4, 8, 16, 32, 64, 128 not additively as in 2 , 4, 6, 8, 10, Multiplication is a huge increase in productivity for a small increase in effort. Its opposite is frustration and futility. Putting in a huge effort for little or no reward.
Authority to rule over means dignity, headship, authority, the ability to be ascendant, to be the head not the tail. Its opposite is being humbled, to eat the dirt, to be crushed and humiliated, to be unable to rise.
In Genesis 3 we see the first curses in operation. The woman is made unfruitful, the man is made to work in futility and the serpent is told he will eat the dirt. The three things that make life good are reversed. Life becomes unbearable. Thus when we are cursed we find life very difficult indeed. No matter how hard we try to rise we never quite make it. Time and time we get to the brink of success only to have it snatched away. Curses can affect health, particularly reproductive health. They can affect earning power and they can affect our ability to have authority and command over our lives and people who are cursed may have to endure lifelong humiliation.
