We don't really know much about the life of the world to come. We get glimpses in Revelation 21, Jesus' teachings about the Kingdom of God as a wedding banquet, Paul's mention of being taken up to the seventh heaven (whatever that means), and this account of Stephen's vision. We do know that Jesus has conquered death for us, and promises life in the world to come. We see all this with the eyes of faith.
