Thy kingdom come, thy will be done, in earth as it is in Heaven. (Matthew 6:10, King James Bible)
And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation: Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you. (Luke 17:21-22, King James Bible)
What is the ‘Kingdom’? In contemporary terms, it is a grass-roots, metapolitical movement, which comes out of the theosis (spiritual development) of individuals and then the actions they take.
