This knowledge alone is but water, unsavoury and cold. And, therefore, if they that have it would humbly offer it up to our Lord, and pray for His grace, He would by His blessing turn their water into wine, as He did at the prayer of His Mother at the marriage feast; that is to say, He would turn their unsavoury knowledge into true wisdom, and their cold naked reason into spiritual light and burning love, by the gift of the Holy Ghost. (John Climacus)

Water is good. Much that is worthwhile can be done with water. But wine is better.

Intellectual knowledge of God is worthwhile. But an intimate relationship with God is better.

Reason is a great gift and essential to the Good. But love gives reason purpose and power.
