Asked by the Pharisees when the kingdom of God would come, He replied to them by saying, The kingdom of God does not come with signs to be observed or with visible display, Nor will people say, Look! Here [it is]! or, See, [it is] there! For behold, the kingdom of God is within you [in your hearts] and among you [surrounding you]. And He said to the disciples, The time is coming when you will long to see [even] one of the days of the Son of Man, and you will not see [it].
Luke 17:20-22 (Amplified Bible)
