When you are saved, you are as they say, born again! You are considered a new creation: 2 Corinthians 5:17, "Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." You are adopted or born into the family of God... a royal family! 1 John 3:1, "Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not." Your sins are removed from you and canceled from your account... in other words, you are FORGIVEN! Micah 7:19, "He will turn again, he will have compassion upon us; he will subdue our iniquities; and thou wilt cast all their sins into the depths of the sea." Once your sins are forgiven, you are en- clothed with the righteousness of God by faith in Christ Jesus: Romans 3:22, "Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe..." You are seated with Christ in authority over all powers of the devil: Ephesians 2:6, "And hath raised us up together, and made us sit together in heavenly places in Christ Jesus." This means that you, as a believer in Christ, will be capable of casting out demons and healing sickness and disease (because you now have authority over sickness and disease, as well as all powers of the enemy). This authority is exercised through faith, so it is also important to cultivate and build your faith in order to fully take advantage of this benefit. Mark 16:15-18, "And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned. And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover." Yes, that means that you, as a believer in Christ, can go fourth and cast out demons and heal the sick... why? Because you have been given authority over sickness, disease and over all powers of the devil! Now don't get me wrong, the more you understand about the ministry of deliverance and healing, the more effective you will be at ministering to others in those areas, but as for the authority needed to cast out demons and heal the sick... that belongs to you naturally as a child of God.
