1 Peter 1:22-25 (NIV)
22Now that you have purified yourselves by obeying the truth so that you have sincere love for your brothers, love one another deeply, from the heart. 23For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God. 24For,
“All men 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 stands forever.”
And this is the word that was preached to you.
