Satan and demonic spirits are topics described in the scriptures that pastors and other Christians want to ignore or of which they are afraid. Even in Jesus' time, when he cast out demons from the demon-possessed man in the cemetery, and the demons went into the swine, the people wanted Jesus to leave. Today, there is very little teaching on demons, demon possession, demon deliverance, and false prophets.

There are three types of spirits in the world: the Holy Spirit, demonic spirits, and our own human spirit. In this book, scriptures are given to test the spirits to see if they are from God. In dealing with demonic spirits, one should first know the enemy, Satan, who is an angel fallen from heaven, is the father of lies, and one who desires to rule the world.

Satan imitates God, possesses men, desires to destroy, and takes men prisoners. A believer in Jesus Christ who is a born-again Christian cannot be demon-possessed because the Scriptures declare that greater is he (Jesus) that is in you than he (Satan) that is in the world. Christians are to put on the whole armor of God to stand against the devil.

The disciples overcame by the blood of the Lamb, the word of their testimony, and they feared not their lives unto death. God gave the disciples power over the demonic spirits, and he gives Christians that power in Jesus's name over the demonic spirits. Scriptures and examples are given on how to recognize and deliver demon-possessed people by using the Word of God. False prophets and ministers of righteousness are also discerned by using God's Word and the fruit of their lives.
