The need for deliverance is manifested by an inability to be free from bondage e.g. mental (emotional), physical, or spiritual normally associated with demon activity. It is God’s desire to bring deliverance to his people.

Job 5:19;

From six calamities he will rescue you;
    in seven no harm will touch you.

Psalms 91:3;

Surely he will save you
    from the fowler’s snare
    and from the deadly pestilence.

II Timothy 4:18;

 The Lord will rescue me from every evil attack and will bring me safely to his heavenly kingdom. To him be glory for ever and ever. Amen.

Hebrews 2:15;

And free those who all their lives were held in slavery by their fear of death.

II Peter 2:9;

 If this is so, then the Lord knows how to rescue the godly from trials and to hold the unrighteous for punishment on the Day of Judgment.

We have been granted the authority in the same way of Jesus to bring deliverance to others.

Mark 16:17;

 And these signswill accompany those who believe: In my name they will drive out demons;they will speak in new tongues;

John 14:12;

 Very truly I tell you, whoever believes in me will do the works I have been doing, and they will do even greater things than these, because I am going to the Father.

1 Corinthians 12:8-11;

⁸ To one there is given through the Spirit a message of wisdom, to another a message of knowledge by means of the same Spirit,⁹ to another faith by the same Spirit, to another gifts of healing by that one Spirit,¹⁰ to another miraculous powers, to another prophecy, to another distinguishing between spirits, to another speaking in different kinds of tongues,^[a] and to still another the interpretation of tongues.^[b]11 All these are the work of one and the same Spirit, and he distributes them to each one, just as he determines.

We must understand that our warfare is with forces of evil

Ephesians 6:12;

 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.

Our weapon is the word of God, our authority and power are from Jesus himself

Mark 16:17;

And these signswill accompany those who believe: In my name they will drive out demons;they will speak in new tongues;

Acts 1:8;

 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”

And that the battlefield is in the spiritual realms

Ephesians 6:10-18;

¹⁰ Finally, be strong in the Lord and in his mighty power.¹¹ Put on the full armor of God, so that you can take your stand against the devil’s schemes.¹² For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.¹³ Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand.¹⁴ Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place,¹⁵ and with your feet fitted with the readiness that comes from the gospel of peace.¹⁶ In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one.¹⁷ Take the helmet of salvation and the sword of the Spirit, which is the word of God.

¹⁸ And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people.

II Corinthians 10:3-5;

³ For though we live in the world, we do not wage war as the world does.⁴ The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.⁵ We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.

Romans 8:9;

 You, however, are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ.

Galatians 5:22-23;

²² But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness,²³ gentleness and self-control. Against such things there is no law.
