The “Kingdom” was already present; which should easily be vindicated in scripture!
Christ told those who had the “kingdom” that it would be taken from them, and given to someone else!
Kingdom is neither a place, or any physical item to be transferred or conferred on any individual.
Kingdom is from a Greek word meaning: power, rule, reign, authority!
That “kingdom” is the power, rule, reign, and authority of God within our lives!
It’s within us, among us, and all around us!
