What are the possibilities for helping my new client cure his “incurable” brain cancer?

We see this as cured following your recent Protocol work and subconscious channeling follow up. As you know, there are no guarantees ever because what is undone can be redone, as we have told you before. He can recreate the illness because of his expectations based on the medical pronouncements of the grim prognosis they have given, so time will tell which will win out—the divine healing or his own expectations. There may be some benefit from making him aware that a request was made on his behalf for divine healing, but this will not be embraced and taken to heart because the level of belief is not sufficient for him to believe fully in these words, producing the desired result. So this will not truly add much in helping a positive outcome, he is simply going to decide his own fate regardless of any action that might be taken by someone coaching him.
