But the hour is coming, and is now here, when the true worshipers will worship the Father in spirit and truth, for the Father is seeking such people to worship him. God is spirit, and those who worship him must worship in spirit and truth.
John 4:23-24
In spirit and truth.
In response to a question about places of worship, Jesus tells a Samaritan woman of a coming shift in perspective. Soon (indeed, sooner than many of the day realized), true worship would no longer be identified with a specific location, neither at Jerusalem (where the Jews worshiped) nor Mount Gerizim (where the Samaritans worshiped). True worshipers would worship in spirit and truth.
But what does it mean to worship in spirit and truth?
