Now that you have purified your souls 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 anew, not of perishable seed, but of imperishable, through the living and enduring word of God. For,
“All flesh is like grass,
 and all its glory is like the flowers of the field;
the grass withers and the flowers fall,
but the word of the Lord endures forever.”

1 Peter 1:22-25
