John 4:23–26. “God Is Spirit”
“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.” The woman said to him, “I know that Messiah is coming (he who is called Christ). When he comes, he will tell us all things.” Jesus said to her, “I who speak to you am he.””
