1 Peter 1:23-25

23For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.

24For, “All people are like grass, and all their glory is like the flowers of the field; the grass withers and the flowers fall, 25but the word of the Lord endures forever.” Isaiah 40:6-8 (see Septuagint) And this is the word that was preached to you.
