Luke 17:21

Within you. That is, meaning either “in your midst” or “in your hearts.” There has been some dispute as to which meaning is favored by the context here. The only other use in the NT of the word here translated “within” clearly has the sense of “inside” rather than “in the midst of’ (see Matt. 23:26). The kingdom of divine grace was certainly not in the hearts of the Pharisees, and it is this fact that has led many commentators to favor the reading “in your midst.” Yet Jesus was clearly addressing the Pharisees (see on Luke 17:20). It should be noted however that, even so, Jesus’ statement does not require the meaning “in your midst.” He could simply be saying to them, “The kingdom of God is not something that you may expect to see by close observation with your natural eyesight. You will discover it, if at all, within your own hearts.”
