1 Peter 1:22-25
22 Since you have in obedience to the truth purified your souls for a love of the brothers without hypocrisy, fervently love one another from the heart, 23 for you have been born again not of corruptible seed but incorruptible, that is, through the living and enduring word of God.
“All flesh is like grass,
And all its glory like the flower of grass.
The grass withers, And the flower falls off,
25 But the word of the Lord endures forever.”
And this is the word which was proclaimed to you as good news.
