3 Extend your hearts, help the poverty of my words. What I shall be able to express, give ear to; on what I shall not be able to express, meditate. Who can comprehend the abiding Word? All our words sound, and pass away. Who can comprehend the abiding Word, save He who abides in Him? Would you comprehend the abiding Word? Do not follow the current of the flesh. For this flesh is indeed a current; for it has none abiding. As it were from a kind of secret fount of nature men are born, they live, they die; or whence they come, or whither they go, we know not. It is a hidden water, till it issue from its source; it flows on, and is seen in its course; and again it is hidden in the sea. Let us despise this stream—flowing on, running, disappearing—let us despise it. “All flesh is grass, and all the glory of flesh is as the flower of grass. The grass withers, the flower falls away.” Would you endure? “But the word of the Lord endures forever.”
