The kingdom age will be for 1,000 years and it will be a physical kingdom right her on this earth. It will be a time where righteousness and goodness dominate. A place where man will be in harmony with each other and with the animal world. A place without satan or his demons , but where Jesus Christ will rule supremely, and universally. It will be a rule that is righteous, just and fair and where sin is dealt with instantly and firmly.
