To answer this question we must first try to identify how the Kingdom of God is defined in the scriptures.
(!).."the kingdom of God is not in words but in power. (1Cor. 4v20)
(2)"..flesh and blood cannot inherit the kingdom of God.(1Cor.15v50).
Then, it is written that, "The kingdom of God is the fruit of the spirit, Love, Joy, Peace, Longsuffering, Gentleness, Goodness, Faith.The question is can all those be found in the hearts of humans?. Yes they most certainly can, but they cannot inherit the kingdom of God.
