1 Peter 1:22-25
1:22 You have purified your souls by obeying the truth in order to show sincere mutual love. So love one another earnestly from a pure heart.
1:23 You have been born anew, not from perishable but from imperishable seed, through the living and enduring word of God.
1:24 For
all flesh is like grass
and all its glory like the flower of the grass;
the grass withers and the flower falls off,
1:25 but the word of the Lord endures forever.
And this is the word that was proclaimed to you.
