1 Peter 1:22-25 NIV
Now 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. For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God. For,
“All people are like grass,
and all their glory is like the flowers of the field;
the grass withers and the flowers fall,
but the word of the Lord endures forever.”
And this is the word that was preached to you.
NIV: New International Version
