Expositor's Bible Commentary Commentary 1 Peter 1:24

"For, All flesh is as grass, And all the glory thereof as the flower of grass. The grass withereth, and the flower falleth:" — 1 Peter 1:24 (ASV)

The quotation from Isa 40:6–8 supports the assertion of the character of God, with its stress on the abiding faithfulness of the Lord’s statements. The quotation comes from Isaiah’s so-called “Book of Comfort,” his inspired messages to an exiled and oppressed people. How fitting the application is to pilgrim Christians (cf. 1 Peter 1:1) in the light of their oppression by the pagan world! The theme of Isaiah’s prophecy is the perishable nature of all flesh and the imperishable nature of the Word of God. To the exiles in Babylon, the message was that while human help is weak, God’s promise of restoration will not fail.
