Holy Ghost Power

Act 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.

Power, dunamis, (like dynamite), strength from God to witness for him and to teach the nations.

Jesus spoke of his power given to us through the Holy Spirit.

Mar 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
Mar 16:16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Mar 16:17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
Mar 16:18 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.

Miraculous power, power beyond human abilities. Power to cast out devils and to speak in new languages. Protective power, through the prompting of the Holy Spirit laying on of hands to heal the sick. Do not tempt God here. Some say there is no healing today or if so, why don't you heal everyone?

Let me tell you a story of a young woman that God sent to me on the Internet in a chat room, I will call her Jane. She received the Lord with tears, had a difficult life before coming to salvation, but one of her spiritual gifts was healing. Another young friend of Jane was staying in a group home where she was living. The friend of Jane slit her wrists, attempting to commit suicide. Jane held her wrists and prayed, the bleeding stopped and there was no scar. Another time she was in a retreat place when a voice told her to get up out of bed and go out into the lobby. There was a man laying on the floor, he had suffered a heart attack. She kneeled and prayed for him and he was healed. A religious group, people of a authority in this sect heard about her healing and they took her to many people. Some were healed, some were not, but she said with tears, I led one person to Jesus before she died. A prominent religious leader was on his death bed. They brought Jane to heal him, she prayed, but he died. They accused her of not praying hard enough! Listen, do not tempt God. He leads us through the Holy Spirit to manifest the gifts as he chooses.

Paul is a good example of a Spirit filled servant of God

Act 28:3 And when Paul had gathered a bundle of sticks, and laid them on the fire, there came a viper out of the heat, and fastened on his hand.
Act 28:4 And when the barbarians saw the venomous beast hang on his hand, they said among themselves, No doubt this man is a murderer, whom, though he hath escaped the sea, yet vengeance suffereth not to live.
Act 28:5 And he shook off the beast into the fire, and felt no harm.
Act 28:6 Howbeit they looked when he should have swollen, or fallen down dead suddenly: but after they had looked a great while, and saw no harm come to him, they changed their minds, and said that he was a god.
Act 28:7 In the same quarters were possessions of the chief man of the island, whose name was Publius; who received us, and lodged us three days courteously.
Act 28:8 And it came to pass, that the father of Publius lay sick of a fever and of a bloody flux: to whom Paul entered in, and prayed, and laid his hands on him, and healed him.

Healing is a gift, but it is directed by the will of God, not by the will of a man. Let God lead you by His Spirit, pray and be obedient.

2Ti 1:7 For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
