“Jesus answered and said unto her whosoever that drinketh of this water shall thirst again; But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a living well of water springing up into everlasting life.” (John 4:13+14)
“Our fathers worshipped in this mountain, and ye say that in Jerusalem
is the place where men ought to worship.” (John 4:20)
“The woman saith unto him, ‘I know that Messias cometh which is called Christ. When he is come he will tell us all things.’” (John 4:25)
“Jesus saith unto her, ‘I that speaketh unto thee is he.’”

God wants people to worship Him in spirit and in truth. The woman was talking about living water which she wanted. Then she changed the subject to theology when Jesus began to point out the way she had been living. (John 4:15- While the woman was talking theology, she found out that she was talking theology with the Messiah Himself. She was changed! She began to share the Good News! We can share better with others after we have been with Jesus and have partaken of the living water.
