Quotes from Dean Davis

all throughout the NT Christ and the apostles envision the Kingdom as coming in two stages only, with the spiritual Kingdom of the Son being separated from the spiritual and physical Kingdom of the Father by a single Consummation at the end of the present evil age.

The one Kingdom comes in two stages: a temporary heavenly reign, followed by an eternal earthly reign, the two being separated by a single Parousia when the High King descends from heaven to consummate all things in final reward and retribution.
