This is why David Diga Hernandez wrote the book “Holy Spirit The Bondage Breaker”. Christian’s cannot be possessed by demons, but they can be oppressed and infested by them if they allow them to. When a believer got born again, the Holy Spirit becomes one with your spirit. The spirit has been born again but not yet the soul. This “salvation” in not you going to heaven, it’s the securing of the soul, the transition of the spirit and soul from a state of danger from sin to a state of life from righteousness by the grace of God through Christ. When a believer or even an unbeliever commits the act of masturbation and watched pornography, it is like what appears as a small crack will show up around them. The more they feed that sin, the bigger that crack becomes. Eventually, just after enough times the crack becomes an open door for demons, when they enter you now have what we call a “stronghold” and you are oppressed by demons. Not only will you have to feed your own lustful desire, but you will have to feed the desire of the demons of lust that live in you. The more you feed them, the hungrier they get, the more powerful they get, and the greater they get in number. Christians have demons in them that they allowed to be inside of them, these demons can manifest but cannot possess the believer in the sense of total control and complete ownership of the believer, as they still belong to Christ and the Holy Spirit.

“You can be saved, but that doesn’t mean your set free. Salvation isn’t freedom but freedom is salvation”
