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."
He would have given thee. By these words Christ testifies that, if our prayers be addressed to him, they will not be fruitless; and, indeed, without this confidence, the earnestness of prayer would be entirely cooled. But when Christ meets those who come to him, and is ready to satisfy their desires, there is no more room for sluggishness or delay. And there is no man who would not feel that this is said to all of us, if he were not prevented by his unbelief.
