Exorcism and Deliverance demands an understanding of the power of the blood of Jesus.  One of  the commands that should be given to a demon is " I claim (spiritual protection) by the blood of Jesus Christ." The believer must be confident of the functions of the blood of Jesus in their life.

Power of the Blood in Redemption

A believer is purchased by the blood of Jesus Christ.

1 Peter 1:18-19  You must know (recognize)that you were redeemed (ransomed from the useless (fruitless) way of living inherited by tradition from (your forefather), not with corruptible things(such as) silver and gold, but (you were purchased with the precious blood of Christ (the Messiah) like that of a (sacrificial) lamb without blemish or spot."

Power of Reconciliation through the Blood

The word "reconcilate" according to Webster's dictionary means "to restore a friendship. "  The blood of Jesus restores our friendship to God.  We were separated by sin.  The blood sacrifice of Jesus Christ brings us back to the presence and person of God. Sin has been pardoned by the blood of Jesus Christ.  

 Roman 3:25 "Christ Jesus, whom God put forward (before the eyes of all) as a mercy seat and propitiation by His blood (the cleansing and life-giving sacrifice of atonement and reconciliation, to be received through faith.  This was to show God's righteousness, because in His divine forbearance he had passed over and ignored former sins without punishment."

The cleansing removes the defilement of sin from our inner being. Cleansing removes the sin from the "old life"  "The pollution of sin, on the other hand, is the sense of defilement and impurity which sin brings to our inner being, and it is with this that cleansing has to do."   (Power in the Blood, pg 58)

1 John 1:7  Be if we (really) are living and walking in the Light, as He (Himself) is in the light, we have (true, unbroken) fellowship with one another, and the blood of Jesus Christ His Son cleanses (removes) us from all Sin and guilt (keeps us cleansed from sin in its forms and manifestations.)

Power of Sanctification through the Blood

Sanctification means union with God.  God is completely holy and his holiness cannot bear sin.  Sanctification  is union with God through the blood of Jesus Christ.  This union is willful separation of his people from sin and from the world.  The followers of Jesus Christ must make a conscious decision to live apart from the world by not being active in worldly behaviors that set itself contrary to the Word of God.  "Thus sanctification is fellowship with God and His dwelling in us.  So it was necessary that God in Christ should take up His abode in the flesh and that the Holy Spirit should come to dwell in us. This is what sanctification means."  P79, Power of the Blood

Power of Union with God Through the Blood

The followers of Jesus always practices obedience to Jesus.  A Christian's honest desire is not to sin.  The flesh is still part of us and we will disobey.  After the honest prayer of repentance, the blood will continue cleanse us of our sin. We can continue in fellowship with Jesus with a clean conscience.  Our union with God is unbroken.

Our union with Jesus is one of intimate dependence.  The blood of Jesus gives us spiritual nourishment.  

 "Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you.  Whoever eats my flesh and drinks My blood has eternal life, and I will raise him up at the last day.  For My flesh is food indeed and My blood is drink indeed.  He who eats My flesh and drinks My blood abides in Me and I in Him."  John 6: 53-56

"All creatures must obtain nourishment from outside of themselves.The natural life was naturally nourished by bread and water.  The heavenly life must be nourished by heavenly food and drink by Jesus Himself."  p 135.

How can we learn to drink the blood of Jesus?  The Holy Spirit is given to all believers as a teacher and comforter.  The Holy Spirit reveals knowledge of Jesus Christ.  The Holy Spirit reveals the spiritual contact believer must have to "eat his flesh and drink his blood."  The Holy Spirit will reveal nourishment though our faith in the power of the blood.
