jehovah's witnesses believe that only 144,000 people, a number found in revelation chapters 7 and 14, will go to heaven to be kings and priests with jesus christ. they say that god will start a worldwide war called armageddon, and the people who do not obey god or worship him the way he expects will be killed. the people who he approves will survive and be given the opportunity to live forever. then god will begin to turn earth into a paradise without crime, sickness, pain, aging, wars or death. they say god will also resurrect (bring back to life) billions of people who died in the past so they can learn about god and have a chance to live in paradise as well.
