Man is not immortal. So far as the element of life is concerned he is not superior to the grass of the field (see Eccl. 3:9-21).
The word of our God.
The revealed will of God constitutes the spiritual food on which man is to subsist (Matt. 4:4; John 6:48-63). Truth never changes, for its Author is “the same yesterday, and to day, and for ever” (Heb. 13:8). Those who come to Him for the sustenance of their souls will never “hunger” (John 6:35), nor will they “thirst” (John 4:14).
