Jesus answered her, "If you knew the gift of God, and who it is who says to you, 'Give me a drink,' you would have asked him, and he would have given you living water."

 It is of the very essence of faith that we should believe that what Jesus says is true. So often we have a kind of vague, wistful longing that the promises of Jesus should be true. The only way really to enter into them is to believe in them with the clutching intensity of a drowning man. If Jesus says a thing, it is not a case of "It may be true"; it is a case of "It must be true."
