I Cor. 12:28-30
The gifts of healing are given by God as a means of supernatural healing of sickness and or disease without natural medicinal or surgical means.
In the gospels we find that Jesus healed the sick. According to Luke 4:18 that was even partial reason for the anointing on his life. In Matthew 10:8 we find that Jesus also gave authority over to the disciples to also heal the sick. Matter of fact we find in the gospels that not only would the disciples do the works that Jesus was doing here on earth, but they would actually do more.
Luke himself was a physician who followed Jesus. He also was with Paul on many missionary journeys. Now even though Luke was a physician it does not say that Luke acted in that profession on these journeys, rather he penned the accounts of what was happening medically among the people. In Acts we find that while Paul was shipwrecked on the Isle of Melita that Luke wrote that Paul laid hands on a sick man and he was healed. Then people brought the sick to Paul and they too were healed in the same manner.
We are not opposed to medical science and are thankful that God has given men and women wisdom in these areas. However, the Gift of Healings is not of the medical science arena, it is beyond it, above it, over it ... it is not natural, it is SUPER-natural.
Supernatural healing is not from medicine nor mere man alone. It is not a diagnosis or by prescribing treatment; it is by the laying on of hands, anointing with oil, by speaking God's Word and obeying the direction of the Holy Ghost that aligns with the Written Word of God.
Any time someone is healed it is wonderful, but when God supernaturally heals a person it remains amazing. It is a sign and wonder to the earth, to men and women of God's wonderful working power and love.
Acts 10:38 ... tells us that Jesus healed those oppressed of the devil; for God was with him.
And although many would like to disclose supernatural gifts of healings as well as the other gifts of the Spirit, it just can not be Biblical sealed. Peter and John went about healing and yes, they were of the twelve original disciples, however, Paul was not and he too healed with Jesus working with him. I Cor. 12:28-30 we find that the gifts were set in the Church (The Body of Christ is the Earth), and the church has not passed away, therefore, the gifts are still available to the Body of Christ (Church), and according to the Word should be coveted.
Now we must understand that there is a difference in the manifestations of the gifts of healings and in receiving healing by simple faith in God's Word. When supernatural gifts are flowing, a person may come to the believe who is operating in the gifts and receiving healing without even knowing anything about the Word of God concerning healing, but healing that comes from simple faith is different, it comes as one believes God and what He has promised through his written Word.
The Word of God speaks of how Jesus healed us. The Word can be sent to heal by prayer, and the Word that we put in front of our eyes ... reading and speaking is also healing. The Word is health to all of our flesh. When we receive health through our faith which comes by the Word it would be considered healing simply through our faith in God.
No matter the means, God wants people healed. We thank God for medical science, we receive God's Word which is truth of how by the stripes on Jesus back we were healed, and we thank him for the wonderful supernatural gifts of the Spirit.
