The short answer is that either you or possibly one or more of your immediate ancestors has placed a block to healing, or by your thoughts and or spoken words you have bought into Satan’s lies and allowed the curse of disease into your life.
Chapter and verse? I hear that a lot but there is no Scriptural support for it at all. I don't buy into theories and philosophies that have no Scriptural support.
Jesus healed. Period, end of story. He didn't psychoanalysis them. Didn't tell them it was anyone else's fault, that it was *generational curses*, or whatever nonsense is the current blame on the afflicted for why they weren't healed, tell them to clean up their lives and get back to Him.
The problem is that nobody is going to be blaming God, so they look for a scapegoat of why God isn't performing as they think He should. That turns it back onto the person who is sick.
Then it's all this time and effort wasted chasing down all this nonsense, which results in people getting their eyes off Jesus, the Author and Perfector of our faith and onto themselves, their circumstances, their ancestors, the enemy, everywhere but on Jesus.
It's a great tactic on the enemy's part of making legalists of people.
If healing is part and parcel with salvation, then it is apprehended in the same manner. Salvation is by faith, then healing is by faith. If healing is by works, then salvation is by works.
I am saved by faith. If I didn't and don't have to clean up my act, get rid of generational curses, etc. to be saved, then I don't to be healed. When people came to Jesus in Scripture, He healed them, simply for the asking.
It's not salvation by faith, healing by works.
God gave the prescription for healing in James. Go to the elders and be anointed with oil.
The long and short of it all is that I know many Godly Spirit filled people who struggle with physical affliction in their bodies, way too many to validate Wrights theology.
Additionally, I personally know many people who have read his book and some who have been to his seminar with me, who have not been healed. Matter of fact, NONE of whom have been healed by his method.
I do not discount the connection between mind and body, BUT God cannot reduced to a formula, nor can healing.
If you read the book, then you know that there is massive scriptural support.
There is little in that book that isn’t referenced to multiple scriptures.
Finally, the testimony of the successful healings seals the deal.
Healing isn’t for everyone. Some just can’t deal with the sanctification process; it’s no fun to be peeled open, and always difficult to confess our ugliness to othwers.
