Bible Quotes Oct 29th 1 Peter 1:24-25

“For, “All people are like grass, and all their glory is like the flowers of the field; the grass withers and the flowers fall, but the word of the Lord endures forever.” And this is the word that was preached to you.”
1 Peter 1:24-25

Some say Peter could not have written his letter because they don’t believe in adult learning. After Peter’s education as a disciple of Jesus, Peter was privileged and had ample opportunity to learn advanced rhetoric. But the wording here is simple and pure. God is holy. God is exalted and above the sin of which people are immersed. In order to deal with sin, it is important not to deal in sin, but to look for God. The simplicity of the words is what informs those who claim Peter could not have written it.

Peter was named by Christ as the rock of the Church This letter may not have been written by him, but was written in his name, probably a decade after the fall of Jerusalem. Peter would have been dead, but still remembered in Rome where this letter probably originated. Christians were being persecuted on the pretext of amoral behaviour.

We are called to live godly lives in pagan society. We are equipped to, by His grace. 

Here, we are called to be holy

"Therefore, with minds that are alert and fully sober, set your hope on the grace to be brought to you when Jesus Christ is revealed at his coming. As obedient children, do not conform to the evil desires you had when you lived in ignorance. But just as he who called you is holy, so be holy in all you do; for it is written: “Be holy, because I am holy.”

Since you call on a Father who judges each person’s work impartially, live out your time as foreigners here in reverent fear. For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your ancestors, but with the precious blood of Christ, a lamb without blemish or defect. He was chosen before the creation of the world, but was revealed in these last times for your sake. Through him you believe in God, who raised him from the dead and glorified him, and so your faith and hope are in God.

Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart. For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God. For,

“All people are like grass,
    and all their glory is like the flowers of the field;
the grass withers and the flowers fall,
    but the word of the Lord endures forever.”

And this is the word that was preached to you."
