1 Peter 1:21-25

21Through him you believe in God, who raised him from the dead and glorified him, and so your faith and hope are in God. 22Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart. Some early manuscripts from a pure heart 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.
