Heaven and earth will pass away, but my words will not pass away.
Forever, O LORD, your word is firmly fixed in the heavens. Your faithfulness endures to all generations; you have established the earth, and it stands fast.
since you have been born again, not of perishable seed but of imperishable, through the living and abiding word of God; for “All flesh is like grass and all its glory like the flower of grass. The grass withers, and the flower falls, but the word of the Lord remains forever.” And this word is the good news that was preached to you. (ESV)
