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.
1 Peter 1:13–25 describes how Christians—those God has caused to be born again—should live now. We must mentally engage in setting all of our hope in God’s future grace for us. We must choose to act as those who are God’s own people, rejecting the evil desires that drove our actions before we knew better. Our choices matter. Our God placed a high value on our lives, paying for them with the blood of Christ. Since God has made us able, we must now strive to earnestly give love to each other.
Peter, the apostle of Jesus, writes a letter to Christians facing persecution to comfort them with the truth of who they are in Christ—children of God with every reason to rejoice in their salvation and future glory in eternity. Next, he urges them to live like the holy ones of God they already are by obeying God now, loving each other earnestly, and placing all of their hope in the endless life to come.
