1 Peter 1:13b-15; 22-2:10
Therefore, once you have your minds ready for action and you are thinking clearly, place your hope completely on the grace that will be brought to you when Jesus Christ is revealed. Don’t be conformed to your former desires, those that shaped you when you were ignorant. But, as obedient children, you must be holy in every aspect of your lives, just as the one who called you is holy.
As you set yourselves apart by your obedience to the truth so that you might have genuine affection for your fellow believers, love each other deeply and earnestly. Do this because you have been given new birth—not from the type of seed that decays but from seed that doesn’t. This seed is God’s life-giving and enduring word. Thus,
All human life on the earth is like grass,
and all human glory is like a flower in a field.
The grass dries up and its flower falls off,
but the Lord’s word endures forever.
This is the word that was proclaimed to you as good news.
Your identity as believers
Therefore, get rid of all ill will and all deceit, pretense, envy, and slander. Instead, like a newborn baby, desire the pure milk of the word. Nourished by it, you will grow into salvation, since you have tasted that the Lord is good.
Now you are coming to him as to a living stone. Even though this stone was rejected by humans, from God’s perspective it is chosen, valuable. You yourselves are being built like living stones into a spiritual temple. You are being made into a holy priesthood to offer up spiritual sacrifices that are acceptable to God through Jesus Christ. Thus it is written in scripture, Look! I am laying a cornerstone in Zion, chosen, valuable. The person who believes in him will never be shamed. So God honors you who believe. For those who refuse to believe, though, the stone the builders tossed aside has become the capstone. This is a stone that makes people stumble and a rock that makes them fall. Because they refuse to believe in the word, they stumble. Indeed, this is the end to which they were appointed. But you are a chosen race, a royal priesthood, a holy nation, a people who are God’s own possession. You have become this people so that you may speak of the wonderful acts of the one who called you out of darkness into his amazing light. Once you weren’t a people, but now you are God’s people. Once you hadn’t received mercy, but now you have received mercy.
