Unlike the water of Jacob's well, which represents the pride we may cling to in our ethnic or national heritage, the life that Jesus offers is alive and real and constantly being renewed.
God is calling people to worship (that is, offer themselves) in spirit (with their whole hearts, not merely in form or ritual) and truth ( honestly and authentically ).
we're not convinced that God could ever truly forgive us... in Jesus, we hear the invitation to come to God just as we are, without pretense, and to worship God in spirit and in truth .
