1 Peter 1:22-25

22You have purified your souls by obeying the truth in order to show sincere mutual love. So love one another earnestly from a pure heart.

23You have been born anew, not from perishable but from imperishable seed, through the living and enduring word of God.

24For all flesh is like grass and all its glory like the flower of the grass; the grass withers and the flower falls off,

25but the word of the Lord endures forever. And this is the word that was proclaimed to you.
