19 “Sir,” the woman said, “I can see that you are a prophet. 20 Our ancestors worshiped on this mountain, but you Jews claim that the place where we must worship is in Jerusalem.”
21 “Woman,” Jesus replied, “believe me, a time is coming when you will worship the Father neither on this mountain nor in Jerusalem. (John 4:19-21)
It is natural for human beings to find a special place on Earth where they can worship God and feel especially close to Him. In the old Testament times God chose the Jerusalem temple to be the special place where God would accept worship from anyone who came with the proper sacrifice and a clean heart.
But now, Jesus is saying that God can be approached by true believers wherever they are. It is no longer necessary to come up to Jerusalem to worship Him:
Yet a time is coming and has now come when the true worshipers will worship the Father in the Spirit and in truth, for they are the kind of worshipers the Father seeks. 24 God is spirit, and his worshipers must worship in the Spirit and in truth.” (John 4:23-24)
The focus, therefore, is not on where we worship, but how we worship.
