There is a heaven (Galt's Gulch) where everyone lives in perfect harmony and happiness... and every bit as wooden and one-dimensional as the Christian heaven.
There is a time of tribulation, which begins by a rapture, the mysterious, almost supernatural magical removal of individuals deemed perfect.

One character (Dagny) is even lifted up to heaven to give her a glimpse of the reward for her moral journey.
