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.
13 Therefore, preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ. 14 As obedient children, do not be conformed to the passions of your former ignorance, 15 but as he who called you is holy, you also be holy in all your conduct, 16 since it is written, “You shall be holy, for I am holy.”
17 And if you call on him as Father who judges impartially according to each one’s deeds, conduct yourselves with fear throughout the time of your exile, 18 knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, 19 but with the precious blood of Christ, like that of a lamb without blemish or spot.
20 He was foreknown before the foundation of the world but was made manifest in the last times for the sake of you 21 who through him are believers in God, who raised him from the dead and gave him glory, so that your faith and hope are in God.
22 Having purified your souls by your obedience to the truth for a sincere brotherly love, love one another earnestly from a pure heart, 23 since you have been born again, not of perishable seed but of imperishable, through the living and abiding word of God; 24 for
“All flesh is like grass
and all its glory like the flower of grass.
The grass withers,
and the flower falls,
25 but the word of the Lord remains forever.”
And this word is the good news that was preached to you.
“…[T]he main object of [1 Peter] is to raise us above the world, in order that we may be prepared and encouraged to sustain the spiritual contests of our warfare. For this end, the knowledge of God’s benefits avails much; for, when their value appears to us, all other things will be deemed worthless, especially when we consider what Christ and his blessings are; for everything without him is but dross. For this reason he highly extols the wonderful grace of God in Christ, that is, that we may not deem it much to give up the world in order that we may enjoy the invaluable treasure of a future life; and also that we may not be broken down by present troubles, but patiently endure them, being satisfied with eternal happiness. Further, when he gives thanks to God, he invites the faithful to spiritual joy, which can swallow up all the opposite feelings of the flesh.”
