“Blessed is the man who endures temptation; for when he has been approved, he will receive the crown of life which the Lord has promised to those who love Him. Let no one say when he is tempted, “I am tempted by God”; for God cannot be tempted by evil, nor does He Himself tempt anyone. But each one is tempted when he is drawn away by his own desires and enticed. Then, when desire has conceived, it gives birth to sin; and sin, when it is full-grown, brings forth death.” ~James 1:12-15 NKJV

The process of deliverance often consists of three main parts: Tearing down strongholds, removing legal rights and then casting out the remaining demons. If you try to cast out demons without taking away the strongholds or legal rights that they are holding onto, then you can’t really expect to achieve a complete successful deliverance. Removing these two blockages is vital in going about a complete and successful deliverance.

demons cannot enter into a person’s body without having some kind of legal permission and legal right to be able to do so. They need some kind of an entry point to be able to get in and attach to someone, and that entry point will be their door opener.
