Sermon Outline 9.20.2026

Title: Gird Up Your Mind
Text: 1 Peter 1:10–16
Big Idea: The greatness of salvation revealed in Christ demands disciplined hope, obedient minds, and lives that reflect God's holiness.
Intro: The size of your salvation sets the standard for your whole life.

I. The Salvation the Prophets Searched (vv. 10–11)

• v.10 - What were the prophets looking for? Their own prophecies. 
• v.11 - What were they asking? Who is it, and when is he coming? 
• Before Bethlehem or the Cross, Christ was at work in the prophets, testifying about himself in advance, through men who couldn’t see his face yet.
• And what was he testifying about? Sufferings, plural. Glories, plural. The cross and the crown. The sufferings were always the plan.

II. The Salvation Angels Lean in to See (v. 12)

• v.12a. - “serving” means “deacon.”  Peter gives three things that have happened since. 
• v.12b. - The prophets served it up. The apostles announced it, and the Holy Spirit powered the preaching. 
• v.12c. That word, look, means to bend over and peer into something. 

III. Gird Up Your Mind (v. 13)

• v.13. "Therefore." Every time you see a therefore in the Bible, you stop and ask, “What is it there for?” 
• There’s one command in this verse: "set your hope." What follows is the how. Gird up your mind, stay sober — that’s how you hope. Peter gives you one command in two parts. 
• "Preparing your minds for action." Your Bible may say: Gird up the loins of your mind. 
  • What does it mean to gird up your mind?
    • It means you refuse mental carelessness.
    • Christians think on purpose.
• "And being sober-minded." Literally, don’t be drunk. 
  • You can be stone-cold sober & still be drunk on something. 
  • Peter says, clear-headed. Steady. Straight.
• v.13c. "Fully." All the way. To the end. Peter is saying, put all your weight into it. 
• What is that one thing? The grace that will be brought to you. Literally: the grace that is being brought to you. Right now.
• "At the revelation of Jesus Christ." Same word as v.7 last week. The unveiling. Peter’s saying, you loved him without seeing him. Now aim your whole hope at the day you will.
• Where is your hope actually sitting? Because your hope always ends up sitting somewhere.

IV. Don't Go Back to What You Didn’t Know (v. 14)

• v.14. "As obedient children." Literally, children of obedience.
  • Children of obedience means obedience is your family name.
  • What’s the obedience? Do not be conformed. Paul uses it in Rom 12.
  • Conformed to what? The passions of your former ignorance. Former. Those desires belonged to another time. They belonged to the version of you that didn’t know. 
• Salvation changes what you want. Ez 36: And I will give you a new heart, and a new spirit I will put within you. A new heart wants new things. 
• Then why do I still want the old stuff?

1. You’re a Christian, and you’re in a fight, and the fight itself is evidence there’s a new heart in there doing the fighting. Dead men don’t struggle.
2. You’ve been in church a long time, know the words, sing every song, but have never actually repented. You’ve got the info without the new heart.

V. Holy Like the One Who Called You (vv. 15-16)

• vv.15-16. The size of your salvation sets the standard for your whole life.

1. God’s character sets the standard. As he who called you is holy. Literally: according to the Holy One who called you.
2. God’s calling supplies the reason. Peter opened this letter calling you elect exiles. You didn’t wander into this family. God called you — effectually, out of darkness into his marvelous light.
3. In all your conduct. Every bit of your walk.

• v. 16 comes from: You shall be holy, for I am holy. Lev 11:44.
  • Leviticus 11 is about food. Clean and unclean animals. God says Be holy, for I am holy in a chapter about groceries.
  • He says it again in Lev 19, and that chapter is about paying your workers on time, leaving the edge of your field for the poor, honest scales in your business, and refusing to hold a grudge.
• Where does the holiness come from? 1 Cor 1:30 — Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption. He is your holiness. 

Closing
Polycarp: when they gave him one chance to lower the standard, to be a little less holy just this once, he had nothing left to lower.
