What a soul tie is...

http://www.greatbiblestudy.com/soulties.php
The Bible speaks of what is today known as soul ties. In the Bible, it doesn't use the word soul tie, but it speaks of them when it talks about souls being knit together, becoming one flesh, etc. A soul tie can serve many functions, but in it's simplest form, it ties two souls together in the spiritual realm. Soul ties between married couples draw them together like magnets, while soul ties between fornicators can draw a beaten and abused woman to the man which in the natural realm she would hate and run from, but instead she runs to him even though he doesn't love her, and treats her like dirt. In the demonic world, unholy soul ties can serve as bridges between two people to pass demonic garbage through. I helped a young man not too long ago break free from downright awful visitations from demons, all due to an ungodly soul tie he had with a witch. The man was a Christian, and the only thing that allowed her to send demonic torment his way, is through the soul tie. Other soul ties can do things such as allow one person to manipulate and control another person, and the other person is unaware to what is going on or knows what is going on, but for no real reason, allows it to continue.
How soul ties are formed
I believe there are other ways which soul ties are formed, but here are some that I am aware of.
Sexual relations: Godly soul ties are formed when a couple are married (Ephesians 5:31, "For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh."), and the Godly soul tie between a husband and the wife that God intended him to have is unbreakable by man (Mark 10:7-9). However, when a person has ungodly sexual relations with another person, an ungodly soul tie is then formed (1 Corinthians 6:16, "What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh."). This soul tie fragments the soul, and is destructive. People who have many past relationships find it very difficult to 'bond' or be joined to anybody, because their soul is fragmented.
Close relationships: King David and Jonathan had a good soul tie as a result of a good friendship (1 Samuel 18:1, "And it came to pass, when he had made an end of speaking unto Saul, that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul."), but bad soul ties can form from bad relationships as well. Idolizing somebody can cause a bad soul tie.
I have heard too that you can create a soul tie with a rock group by becoming obsessed with their music. Which explains the strong pull towards certain music that seems almost irresistible.
Vows, commitments and agreements: Vows are known to bind the soul (Numbers 30:2), marriage itself consists of vows and binds the two people together (Ephesians 5:31), therefore I have little reason to overlook the concept of vows or commitments as being a means to create a soul tie.
How to break a soul tie
1. If any sins were committed to cause this soul tie, repent of them! Fornication is perhaps one of the most common ways to create nasty soul ties.
2. If gifts were given to you by the other person in connection with the sin or unholy relationship, such as rings, flowers, cards, bras, etc. I would get rid of them! Such things symbolize the ungodly relationship, and can hold a soul tie in place. If you are still friends or in a relationship (just now it's no longer an ungodly relationship), like say a boyfriend/girlfriend relationship, except you've repented of and forsaken the unholy practices you used to do in your relationship, then I don't feel it is necessary to destroy all the gifts and things that you have been given. I would still encourage you to get rid of anything that symbolizes the ungodly practices in the relationship though, such as if a guy gives a girl a bra and panties with his initials on them during fornication. I wouldn't encourage you to hang on to such things that symbolize sin or that are wrong to give each other before marriage. Things such as flowers and love letters given during an adultery should be destroyed.
3. Any rash vows or commitments made that played a part in forming the soul tie should be renounced and repented of, and broken in Jesus' name. Even things like "I will love you forever", or "I could never love another man!" need to be renounced. They are spoken commitments that need to be undone verbally. As Proverbs 21:23 tells us, "Whoso keepeth his mouth and his tongue keepeth his soul from troubles." The tongue has the ability to bring the soul great troubles and bondage.
4. Forgive that person if you have anything against them.
5. Renounce the soul tie. Do this verbally, and in Jesus' name. Example, "In Jesus' name, I now renounce any ungodly soul ties formed between myself and ______ as a result of _______________ (fornication, etc.)."
6. Break the soul tie in Jesus' name! Do this verbally using your authority in Jesus. Example, "I now break and sever any ungodly soul ties formed between myself and _________ as a result of ______________ (fornication, etc.) in Jesus' name."
Dangers of fornication and adultery
Sexual play (intercourse, oral, etc.) is supposed to be for marriage. Whether or not you're a Christian, it's wise to keep this rule. It not only opens a person up to diseases and curses such as HIV, but it also creates unholy soul ties (spiritual bondage between one person and another), which can cause unclean (demonic) bondages to transfer from one person to the other.
Brief Biblical look at soul ties
1 Corinthians 6:16, "What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh."
Obviously the two didn't get married, but something spiritual "happened" when they were joined physically in the act of sex. They were "joined"; their souls were "tied." Often there are men who have an adultery with a prostitute (one night stand), and afterwards, even years later, are still thinking about that girl! That is because a soul tie has been created.
Dangers of unholy soul ties
Unholy soul ties can be 'demonic bridges' between one person to the next. For example, if you were to have extra-martial sex with somebody who was involved in the occult and had horrible fears of demons, and was afraid of her own shadow.. you could end up with the same kind of tormenting spirits as she has, and be just as fearful (although you could have been afraid of nothing before sleeping with her!). This is because you are not only opening yourself up to a curse for sexual sin, but also a soul tie with a person who is tormented ```````by demons.
Don't think to yourself that the person you are having sex with is clean from demon spirits. Demons spirits can cause everything from depression to horrible fears (panic attacks, etc.) and a huge list of problems that people face everyday!
Struggle against compulsive lustful desires?
If you have a compulsive struggle with lust, bad thoughts, etc., you may be struggling with what they call an iniquity. An iniquity is like a weakness (lust, anger, pride, etc.) and it could have been handed down from your ancestors (Exodus 20:5) or it could have been opened up in your own life (Lev 5:17).
You might want to check out a book titled Breaking Generational Curses & Pulling Down Strongholds by Vito Rallo. It's a real eye opener to how these iniquities get started, how they operate, and how to go about breaking yourself off from them.
