What will be the domain of the church age believer in eternity?
The church age believer's domain in eternity will be the heavenlies, specifically the whole area of outer space. As the Body of Christ, church age believers will rule the heavenlies, while Israel will have the earth. Their resurrected bodies may also interface with millennial citizens in flesh and blood.
Les explains that the whole area of outer space is going to be the domain of the church age believer, because we are told that we are going to rule the heavenlies. Israel is going to have the earth, and that will be given to them. But the believers of the church age, the Body of Christ, are going to rule in the heavenlies. He also suggests there will be a certain amount of interfacing between those in resurrected bodies and the millennial citizens who will be in flesh and blood. Les further emphasizes that there are areas of reward every believer should work for, while salvation itself is not by works but is a gift, as Romans 6:23 teaches.
