If you believe that the body can remain sick and that you need to become at peace with it being sick and just accept it, you will have NO HOPE.
The only way to have hope, is to accept that the body can only be sick IF YOU CHOOSE IT TO BE SICK, and THEREFORE... IF you were to become able to truly choose again, your body WILL HEAL.
The belief in an unhealable sickness is a BELIEF IN HOPELESSNESS. You DO NOT WANT THAT!
In that taking of responsibility for everything you are experiencing, THERE IS HOPE, because a CURE is possible. Do you really believe God has no ability or will to HEAL YOU COMPLETELY?
Believing that the body is sick for any reason other than that your mind made it so, wanted it so, and maintains it so, and that your mind can UNDO THAT if it chooses, can only leave you hopeless and in despair.
But to admit to that level of responsibility is not going to be PRETTY, because at first you will think it means you've done a really dumb thing to yourself, that you're terribly guilty for attacking yourself. This is an ego defense. You have to go past that to realize that taking responsibility means YOU ARE RESPONSIBLE FOR BEING ENTIRELY INNOCENT.
In that innocence, which is accepting the atonement, you will be CURED of all sickness and suffering. And that is VERY MUCH WORTH believing in.
