1 Peter 1:22-25

Now, because of your obedience to the truth, you have purified your very souls, and this empowers you to be full of love for your fellow believers. So express this sincere love toward one another passionately and with a pure heart. For through the eternal and living Word of God you have been born again. And this “seed” that he planted within you can never be destroyed but will live and grow inside of you forever. For: Human beings are frail and temporary, like grass, and the glory of man fleeting like blossoms of the field. The grass dries and withers and the flowers fall off, but the Word of the Lord endures forever!
