Quote from A Course in Miracles Text Chapter 13 - THE GUILTLESS WORLD.

T-13.XI.7. Have faith in only this one thing, and it will be sufficient: God wills you be in Heaven, and nothing can keep you from it, or it from you. 2 Your wildest misperceptions, your weird imaginings, your blackest nightmares all mean nothing. 3 They will not prevail against the peace God wills for you. 4 The Holy Spirit will restore your sanity because insanity is not the Will of God. 5 If that suffices Him, it is enough for you. 6 You will not keep what God would have removed, because it breaks communication with you with whom He would communicate. 7 His Voice will be heard.
