Jesus gave His life that you could be free; He came to set the captives free. What we do when we need deliverance from the enemy's attack is repent for opening the door to the enemy and then command the demons to go:

Repent for fear...confess all of your fear before the Lord and ask Him to forgive you for entertaining this demon. Then, get a hold of it and cast it out. Make it go by the strength of your will.

Repent for rebellion...confess it and ask God to forgive you. Then, cast out a deaf and dumb spirit, you can identify it by the confusion it brings to your mind.

Repent for rejection (receiving rejection and for rejecting others)...confess it and ask for forgiveness. Then, cast out a spirit of the antichrist--this spirit is against everything that is pure and holy.

Repent for unforgiveness...confess all unforgiveness and ask God to forgive you and then release and forgive everyone who has hurt you or come against you in any way. Then, cast out a spirit of infirmity which keeps you hopeless, helpless, disabled, unable, sick, etc.

Repent for resentment...confess all areas of resentment and ask the Lord to forgive you and release you. Then, cast out a spirit of jealousy.

Repent for witchcraft...confess your desires and efforts to control others through your attitudes and behavior. If you have ever been involved in the occult, even reading horoscopes, playing with ouija boards, or anything else, repent and ask the Lord to forgive you. Then, cast out a spirit of divination.

Repent for pride. Cast out a haughty spirit.

Repent for hypocrisy and deception. Cast out a lying spirit that has caused you to live in fantasy.

Repent for idolatry...confess all areas where you have put people or things ahead of God. Then, cast out a spirit of whoredoms.

Repent for lust, whether sexual lust or greed or desire for approval and attention. Then, cast out unclean spirits. These usually come in groups, so make them all go.

Repent for defilement for the ungodly places you've been, things you've seen, heard or read. Repent for entertaining pornography and all that goes with it. Then, cast out a perverse spirit.

Repent for bitterness. Release all hurt and injury from the past and ask God to forgive you for being a victim of life's circumstances instead of taking your proper position of being victorious in Christ. Then, cast out a spirit of bondage.

Repent for discontentment. Cast out a seducing spirit that has seduced you into wrong attitudes and behavior.

Repent for depression, discouragement, disappointment. Cast out a spirit of heaviness.

Repent for laziness, procrastination, a desire to die, for wanting to give up, etc. Then, cast out a spirit of death.

Now, ask the Lord to fill all the empty places with His precious Holy Spirit and forbid those demon spirits to come back. Then, you MUST keep the doors of your flesh closed, i.e. don't entertain the things that you repented of again. Stay clean. Feed yourself on the Word of God; stay in prayer; turn from all evil.
