Deliverance is the application of God's power to disconnect a person from the influences and power of the dark forces from the devil. It employs the power in the blood of Jesus to enforce the covenanted declaration of Christ to set the captives free. (Luke 4:18; Luke 10:17-19).
A delivered soul has the ability to sence the influence and manipulation of the devil. He is not under the influence and control of evil spirits or demons. Resisting deliverance is to assume that all is well. 1 Peter 5:8 sayd the enemy is going to and fro seeking for whom he may devour. Unfortutely for most christians, the devil does not devour just unbelievers. Deliverance is when you employ the power of God to resist the enemy as as Apostle James says, "...Resist the devil, and he will flee from you." James 4:7.
