What does 1 Peter 1:24 mean?
This verse must be taken together with verse 25. Peter quotes from Isaiah 40:6–8 to back up his statement in verse 23 that we are born again through the undying Word of God. Human life, though intense and beautiful in many ways, comes and goes in a season. Even the most productive, most privileged, most adventurous of mortal lives begin to fade just as they get underway.This is understood and grieved by people of every culture, every generation and every belief system. Human life is achingly temporary. Peter writes this letter, in part, to remind His readers that God has provided (by grace and through faith in Christ) a true home and a secure future on the other side of this temporary life. In Him, we have hope of a future without end.
However, the specific point he is making here is about the word of the Lord, and it concludes in verse 25.
