Jesus Came to Set the Captives Free

Like angels, demons are created beings. Demons, or devils, are evil spirits that work against God’s will. The late Derek Prince, a general of deliverance, called demons “persons without bodies.” That’s a fair description, since demons have a will, intelligence and a personality.
Demons are often called by their assignment or function, such as anger, lust or bitterness. Ultimately, all demons have the same assignment. Jesus exposes the plans of the enemy in John 10:10—to steal, kill and destroy. All demons work to achieve this end. A spirit of infirmity, for example, tries to destroy your health. A spirit of poverty works to steal your prosperity. A spirit of anger will kill your relationships.
Just as Jesus Himself needed a physical body to walk the earth legally, demons need a body to operate in the physical realm. You could be demonized in your emotions, in your mind, in your body or your physical lusts. The good news is whatever demon is oppressing or depressing you, the other half of John 10:10 remains true: Jesus came to give you abundant life. You can deliver yourself from evil and walk in your destiny in Christ.
