Some years back, Charles and Frances Hunter took the hinterlands of Charismania by storm with the Method.
A learnable, duplicatable method...of healing. The Method was arrived at with the help of a Christian chiropractor. In practise it was a Holy Ghost spinal adjustment in Jesus' name. Now, I am a recipient of blessing from this practise. My back was verifiably healed by this, and I have prayed for people thusly and seen amazing improvement in them (I say this to God's glory, and not to do a Pharisee dance.) I shall not discuss the "leg-lengthening" hobby indulged in by some.
The positive aspect of this, and some of Kenneth Copeland's teaching, is that it teaches one to pray proactively, as Jesus did. Not "Please, God, please maybe make Johnny better, and return him to a reasonable portion of health" weenie whining, but rather taking authority by Jesus' authority ("in Jesus' name" is not a kabbalistic formula. Rather it is proclaiming that as a child of God, you have the Very Authority of God's Son Jesus. Only if you aren't, you don't. Ask the sons of Sceva.) In Jesus' name, BE HEALED! Spine, line up. Glands, work right. Storm, be muzzled. Demon, come out.
On the flip side, despite the popular opinions about, Jesus is not our Lord and Personal Butler. We cannot grasp the bell-pull and proclaim "Parker, get out the Rolls Royce.". Ultimately it is the will of God that prevails, but He is gracious in that we have the opportunity to let Abba (Daddy) know our druthers.
Good King Hezekiah complained of his impending death, and God heard him, and granted him more years. The bad news is that he lived to father ....
Manasseh was twelve years old when he began to reign, and reigned fifty and five years in Jerusalem. And his mother's name was Hephzibah.
And he did that which was evil in the sight of the LORD, after the abominations of the heathen, whom the LORD cast out before the children of Israel.
For he built up again the high places which Hezekiah his father had destroyed; and he reared up altars for Baal, and made a grove, as did Ahab king of Israel; and worshipped all the host of heaven, and served them.
And he built altars in the house of the LORD, of which the LORD said, In Jerusalem will I put my name.
And he built altars for all the host of heaven in the two courts of the house of the LORD.
And he made his son pass through the fire, and observed times, and used enchantments, and dealt with familiar spirits and wizards: he wrought much wickedness in the sight of the LORD, to provoke him to anger.
And he set a graven image of the grove that he had made in the house, of which the LORD said to David, and to Solomon his son, In this house, and in Jerusalem, which I have chosen out of all tribes of Israel, will I put my name for ever:
Neither will I make the feet of Israel move any more out of the land which I gave their fathers; only if they will observe to do according to all that I have commanded them, and according to all the law that my servant Moses commanded them.
But they hearkened not: and Manasseh seduced them to do more evil than did the nations whom the LORD destroyed before the children of Israel. (2 Kings 21:1-9)
So be careful what you pray for.
The thing is, as far as the practise goes, Julian did much the same as the Method, without the spiritual element, and it worked. He did it with grace, and out of concern for my well-being. May he have returned a hundred-fold the blessing he was to me. In my understanding, healing and blessing come from God. I can recall of NO healing coming from Satan, or Baal, or the Asherah, or from Molech's outstretched arms.
Thank God, and his Son, for every good and perfect gift.
