1 Peter 1:22-25

Now that you've dedicated yourselves by following the truth, love each other sincerely like a true family. You've been born again, not the product of a mortal “seed,” but immortal, through the living, eternal word of God. For: “All people are like grass, and all their glory like wildflowers. The grass withers and the flowers fall. But the word of the Lord remains forever.” This word is the good news that was explained to you.
