1 Peter 1:22-25

New Matthew Bible

²² And inasmuch as you have purified your souls through the Spirit, in the obedience of truth with brotherly love unfeigned, see that you love one another with a pure heart fervently. ²³ For you are born anew, not of mortal seed, but of immortal: by the word of God, which lives and lasts forever.

²⁴ For all flesh is as grass, and all the glory of man is as the flower of grass.  The grass withers, and the flower falls away, ²⁵ but the word of the Lord endures forever. And this is the word which by the gospel was preached among you.
