“Jesus answered and said to her, “Whoever drinks of this water will thirst again, but whoever drinks of the water that I shall give him will never thirst. But the water that I shall give him will become in him a fountain of water springing up into everlasting life.” John 4:13,14 . “The Lord clarifies that this well is the gift of the Holy Spirit, a spring that flows from a living Source. The Holy Spirit is a Source of eternal life as well…This living water is great, for it is the gift of the Holy Spirit…may it flow within me, may this that gives eternal life flow in and over me.” St Ambrose
