For, "All flesh is like grass, And all of man's glory like the flower in the grass. The grass withers, and its flower falls;
The grass withereth, or, has withered. Many think that this refers only to the outward man; but they are mistaken; for we must consider the comparison between God’s word and man. For if he meant only the body and what belongs to the present life, he ought to have said, in the second place, that the soul was far more excellent. But what he sets in opposition to the grass and its flower, is the word of God. It then follows, that in man nothing but vanity is found. Therefore, when Isaiah spoke of flesh and its glory, he meant the whole man, such as he is in himself; for what he ascribed as peculiar to God’s word, he denied to man. In short, the Prophet speaks of the same thing as Christ does in John 3:3, that man is wholly alienated from the kingdom of God, that he is nothing but an earthly, fading, and empty creature, until he is born again.
