Not their earthly bodies.
Do you believe in eternal life?
Not sure what you are trying to point out. The point is, people die. You will die, I will die. Unless Christ returns in our lifetime, everyone alive today, will die. The apostles died. Peter was crucified upside down, Paul was beheaded, Stephen was stoned to death.
Do you believe in eternal life?
Yes. My (dead) body will be resurrected upon Christs return. But I will be dead prior to that. My spirit will return to Christ and return to my resurrected body when Christ commands it so.
