Hi Saint, Prophetically speaking, National Israel, made of the end-time believing remnant, has a future earthly destiny to re-populate the earth (along with some gentiles) and to act as His priests (the 144,000+) during the millennium. The church (spiritual Israel) has a heavenly destiny although I believe we will be going back and forth from heaven to earth as Christ wills, imo and yes some of us saints will be reigning on earth, but certainly not all.
