13. With what fountain then wilt thou be overflowed, and whence runneth such a torrent of His Pleasure? “For with Thee,” saith he, “is the fountain of Life.” What is the fountain of Life, but Christ? He came to thee in the flesh, that He might bedew thy thirsty lips: He will satisfy thee trusting, who bedewed thee thirsting. “For with Thee is the fountain of Life; in Thy Light shall we see light” (ver. 9). Here a fountain is one thing, light another: there not so. For that which is the Fountain, the same is also Light: and whatever thou wilt thou callest It, for It is not what thou callest It: for thou canst not find a fit name: for It remaineth not in one name. If thou shouldest say, that It is Light only, it would be said to thee, Then without cause am I told to hunger and thirst, for who is there that eateth light? It is said to me plainly, directly, “Blessed are the pure in heart: for they shall see God.” If It is Light, my eyes must I prepare. Prepare also lips; for That which is Light is also a Fountain: a Fountain, because It satisfieth the thirsty: Light, because It enlighteneth the blind. Here sometimes, light is in one place, a fountain in another. For sometimes fountains run even in darkness; and sometimes in the desert thou sufferest the sun, findest no fountain: here then can these two be separated: there thou shalt not be wearied, for there is a Fountain; there thou shalt not be darkened, for there is Light.
