There is a Christian religion, that does not believe in Hell, and the Trinity,and the immortal soul, but it also does not believe in the Devil, Demons, or Rulers in Heaven. They do not tell about Jehovah. And they might do things, that are done by the World of mankind. They believe that Jesus is going to come back on the Earth.
Jehovah's Witnesses have hope, as S.Morley asked. Otherwise, they might leave, if they did not have it.
