I have noticed that some people, when they are ill, do not actually want to get better. For them, illness seems to be a reward or something, and they like to talk about it as if it is something which they earned after a lot of struggle. It could be because they want others to sympathize with them.
I just know how to bring about healing. I love people who do not accept an illness and who love to be healed. It is easy to give up and remain ill, but it takes courage to decide that you want to be healed and then go about it.
