But whosoever drinks of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.
All Commentaries on John 4:14 Go To John 4
Cyril of Alexandria
AD 444
The woman of Samaria proposing, as a hard question and difficult to cope with. Art Thou greater than our father Jacob; the Saviour most skilfully avoids all boasting, not saying clearly that He is greater, yet from the nature of the actions does He persuade her to approve Him who excels. Therefore He shews that incomparable is the difference between the spiritual waters, and the sensible and grosser ones, saying, Whosoever shall drink of this water shall thirst again, but he that is filled (saith He) with My water, shall not only be shewn to be superior to thirst henceforth, but he shall have in him a well of water able to nourish him to eternal life. Therefore He that giveth the greater, is greater (saith He) than he that hath the less, and the worsted will not carry off the same glory as the conqueror.
We must know again, that the Saviour here calls the grace of the Holy Ghost water, whereof if any be partaker, he shall have the gift of the Divine teaching evermore flowing up within him, so as no more to be in need of admonition from others, yea rather, readily to suffice to exhort those who thirst after the Divine and heavenly Word, such as were some yet living in this present life and upon earth, the holy Prophets and Apostles, and the heirs of their ministrations, of whom it was written, And ye shall draw water with joy out of the wells of salvation.
