The Kingdom is Not with Observation
The kingdom comes in God's manner, not the world's spectacle.
Jesus resists a purely external, measurable expectation and insists that the kingdom is present in a way that demands discernment.
Scripture
Luke 17:20-21
20 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:
21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
