1 Peter 1:23-25

being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever. For All flesh is as grass, And all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
