“Say to them that are of a fearful heart: be strong, fear not, behold your God.”

"These passages stand in need of no commentary. They are shining and manifest as the sun, and glowing and luminous as light itself. Every fair-minded person is led, by the fragrance of these words, unto the garden of understanding, and attaineth unto that from which most men are veiled and debarred.

Unto many things did He refer, but as He found none possessed of a hearing ear or a seeing eye He chose to conceal most of these things.
