The following is mostly a sermon about one word, “Therefore.” It appears at the beginning of verse 13. It means that everything that Peter commands us to do—and there are four commands in this passage—is in response to what God has already done for us. I conclude by reflecting on Peter’s emphasis on the mind: living a Christian life must involve thinking rather than just feeling. The main way that we “prepare our minds for action” is by devoting ourselves to God’s Word, the Bible.
Sermon Text: 1 Peter 1:10-21
Much to my parents’ horror, my best friend in eighth and ninth grade was a guy named Jason. My parents were horrified because over the course of those two years, Jason became a punk-rocker—during a brief period of time when punk and punk-rock fashions were popular among a small subsection of my high school. Not only did Jason listen to punk rock, he shaved his head into a mohawk—not a “faux”-hawk, a real mohawk—and dyed it orange. He wore safety pins in his ears. He wore ridiculous punk-rock clothes, including a fashionably torn blue-jean jacket with these words painted on back: “Non-conformists unite!”
Non-conformists unite! He became famous, or infamous, around high school for this slogan, which he eventually spray-painted on an outside wall of the high school, an action for which he got suspended. But everyone knew him as that “non-conformists unite” kid—and I was known as the friend of the “non-conformists unite” kid. Regardless, Jason apparently failed to see the irony of the slogan “Non-conformists unite!” “Hey, all of you non-conformists out there!” he seemed to say. “Why don’t we all get together and form a social club?” It was as if he were saying, “Non-conformists conform!”
Which just goes to prove just how difficult it is to be a non-conformist. Going along to get along, by contrast, is much less lonely than being a non-conformist. All the kids listening to Prince and wearing polo shirts with their collars turned up had more friends!
In today’s scripture, the apostle Peter gives four imperatives—four commands—in these verses. One of them is “do not conform to the evil desires you had when you lived in ignorance.” There are three other commands. Verse 13: “Set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ.” That’s number two. Verse 15: “Be holy in all your conduct, since it is written, ‘You shall be holy, for I am holy.’” That’s three. Then verse 17: “Conduct yourself with fear throughout the time of your exile.” Four commands. Why are these commands important for us to follow?
Because, as I said last week when I introduced this sermon series on 1 Peter, the most important theme of the letter is one that couldn’t be more relevant for our lives: How can I be truly happy in life—how can I be satisfied in my life; how can I be fulfilled in my life; how can I know true joy in life—regardless of whatever it is that I’m going through right now? Peter is writing to a group of Christians who are suffering. They are being persecuted for their faith; some of them are even facing death—martyrdom—for their faith. That’s in addition to the routine suffering and hardship they experienced not as middle-class Americans living in the 21st century, but as mostly poor people and slaves living in the first century. Can you imagine? He compares the trials that these Christians are enduring to a fiery furnace used to refine gold—to purify it, to make it stronger, more precious. We can be confident, Peter says, that God is using all the bad stuff to make these believers into better, more faithful, stronger Christians.
But in the meantime, Peter says, even as they’re in the midst of these trials, something amazing can happen: you can have joy; you can have deep and lasting happiness. Listen. Verse 6: “In this”—in what? In this “inheritance” that we have waiting for us in heaven—“In this you now rejoice.” When do you rejoice? Right now. He goes on in verse 8: “You rejoice”—you rejoice when? Now. “You rejoice with joy that is inexpressible and filled with glory.”
Don’t you want that? Don’t you want some “inexpressible joy,” which you can experience regardless whatever you’re going through? I mean, let’s put things in perspective: We’re probably not being persecuted very much; we’re definitely not being arrested and killed because of our faith—praise God! And yet if you’re like me, you still have enough hardship, and suffering, and trials, which can easily knock you off balance and keep you from being happy and joyful. Amen?
See, we usually view the trials that we face as interruptions to our happiness. We usually view suffering and joy as mutually exclusive. Right? We say, “I can be happy… so long as I still have my job next week.” “I can be happy… so long as my team wins.” “I can be happy… so long as she’ll say ‘yes’ and go with me to the prom.” “I can be happy… so long as I don’t need hip replacement surgery.” “I can be happy… so long as my kid is able to keep the Hope Scholarship next semester.” “I can be happy… so long as our church can pay its apportionments.” I say that! “I can be happy… so long as my marriage is O.K.” “I can be happy… so long as that biopsy turns out to be negative.”
Notice that the apostle Peter is telling us, “You can be happy—I mean deeply happy—inexpressibly joyful—no matter what is going on in your life. And it won’t depend on external circumstances. That’s what I want.
But I feel like God’s Word today is judging me. Is it judging you? Because far too often, I let my happiness depend on all these other things…
Which is why I need to hear these four commands… and you do, too. Because Peter is telling us what we need to do if we want to be happy.
But before we get to these commands we need to notice verse 13. It includes this critically important, often overlooked, little word: “Therefore…”
Therefore. The “therefore” at the beginning of verse 13, like the “therefore” that we find in so many other places in the New Testament, means that what follows the “therefore” is the logical response to what has come before it. In other words, “As a result of everything else that I’ve just been telling you, here’s what you need to do.” And what has Peter been telling these Christians? In 1 Peter 1:1-12, he has given them a beautiful, concise summary of the gospel of Jesus Christ.
He has been telling them all about what God has already done for them. “Before the foundation of the world,” Peter tells them, “God already knew and loved you. God loved you so much, he wanted to rescue you from your sins—so that you could be with him for all eternity. God had a plan for you—you were a part of God’s plan—forever. So he called you, and he gave you the grace to respond to his call. And when you did, he gave you a new birth—which meant you were now part of God’s family. And he gave you power to live your life in a new way. And as if that weren’t enough—he’s guarding this treasure for you in heaven, and he’s protecting you right now so that you’ll be able to receive it one day—either after you die or when Christ comes again. But Peter says that it’s a sure thing, it’s a done deal, as far as God is concerned.”
My point is, before Peter tells us what we have to do, he’s already told us what God has done for us—through the life, death, and resurrection of Jesus Christ. Salvation, he says, is a completely free gift paid for by Christ’s precious blood on the cross; it’s all grace from first to last. There’s nothing we can do to earn it or make ourselves worthy of it. But you say, “Yes, but we have to receive God’s gift of salvation.” Well, that’s true, but our receiving this gift isn’t much! It’s practically nothing!
I have a friend on my blog who’s always arguing with me about this. Not that God doesn’t do most of the work, but we still have to do some things to contribute to our salvation. He said, “Look at Zacchaeus, the tax collector. It was only after he says he’s going to give back all the money that he’d stolen from people that Jesus said, “Truly I tell you, today salvation has come to your house.” And I said, “Yes, but I’ll match Zacchaeus with the thief on the cross, for instance. He’s nailed to a cross. He literally can’t do anything to be saved. Or the woman caught in adultery—she hasn’t done anything before Jesus pronounces her forgiven. Or the paralytic with the four friends. He’s helpless and just sort of lying there—doing nothing. Unlike Zacchaeus, each of these people is saved prior to doing anything other than placing their faith in Christ. And Zacchaeus doesn’t prove my friend’s point anyway: his resolve to give back the money he stole was a sure sign of a saving faith he already possessed.”
See, my friend is worried that if preachers like me talk too much about free grace it will lead to a kind of “easy-believism” that doesn’t demand repentance and good works. And look, I know “easy-believism” happens. But when it does, the problem isn’t that they’ve received saving grace too cheaply; the problem is they haven’t received it at all! That’s why Paul warns us, “Examine yourselves, to see whether you are in the faith. Test yourselves.”[1] If our lives are not “bearing fruit in keeping with repentance,” then the problem isn’t what we do or don’t do; the problem is that we don’t have saving faith to begin with! Or if you had it to begin with, you don’t have it now. So test yourself and see!
Because the “therefore” in verse 13 means that if we do have saving faith, then the behaviors that Peter describes in today’s scripture will naturally follow… We will naturally want to follow these commands, including the commands to “set your hope fully on the grace” that will be ours when Christ returns, and to “not be conformed to the passions of your former ignorance,” and “to be holy in all your conduct.”
So, let’s look at the first command: “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.” Notice the emphasis on using our minds. In order to “set our hope” fully on God’s grace, we have to use our minds. Paul says something similar in Romans 12, when he talks about non-conformity: “Do not be conformed to this world, but be transformed by the renewal of your mind.”
This emphasis on the mind would have made perfect sense to the people whom Peter was writing to: If you’re suffering—if you’re enduring violent persecution—you can’t depend on your feelings. Your feelings are telling you that the situation you’re in is hopeless. They need to rely on something deeper than their feelings; they need to rely on their minds. They need to think things through. They need theology. More than anything, they need to know and understand and be able to apply to their lives the truth of God’s Word!
Brothers and sisters, is God’s Word one of the most important parts of your life? Is it? Are you reading and studying the Bible regularly—every day? You say, “I don’t have time for that.” But you know that’s a lie. You have time for so many other things that you do every day… watching Netflix. Reading about your friends on Facebook or Instagram. Keeping up with the Braves or the Bulldogs. Driving your kids back and forth to any number of extracurricular activities. I’m not saying anything is wrong with these lesser things, but they are lesser things compared to feeding your mind with the “bread of heaven” that the Lord gives us through his holy Word!
So of course we have time for God’s Word! Our reason for so often ignoring it must be something else.
Do we believe God’s Word? I bring this up reluctantly, especially because my boss is here… But despite what you may have heard, the main question that our denomination is struggling to answer right now isn’t related to sex and marriage, however important those questions are: The main question is, Can we trust God’s Word, or can’t we? We know what it says. Do we believe it? And if we don’t believe it, why not? It’s often said, in these arguments about homosexuality and issues pertaining to the LGBTQ that Jesus never said anything about it. If it were so important, why doesn’t Jesus mention it? Why are we threatening as a denomination to divide over something that Jesus never mentions.
I’m sorry. I don’t think that’s a good argument. In part because notice what Peter tells us in verse 11 about the prophets who wrote in the Old Testament. He says, “Concerning this salvation, the prophets who prophesied about the grace that was to be yours searched and inquired carefully, inquiring what person or time the Spirit of Christ in them was indicating when he predicted the sufferings of Christ and the subsequent glories.” He says that these prophets were writing under the inspiration of the Spirit of Christ within them. We can apply that same principle to all the inspired writings of the Old and New Testaments: The Spirit of Christ spoke through these writers, guiding what they wrote. Would this same Jesus Christ say something to us today that contradicts what he said two-thousand years ago? I just can’t comprehend that.
And you might say, along with many other people in our culture, “But I don’t understand why the Bible says we have to live like this and do these things.”
To which I ask, “Why do you expect to always understand the ‘why’ of what God tells us in his Word?”
You know how young children ask “why” all the time. I was no exception when I was a little kid. I asked “why, why, why?” My mom was famous for answering, “Because I said so!” Which is the most unsatisfying answer of all, of course. Although I tried to avoid answering my own kids that way when they were young, you have to admit that “because I said so” is a pretty good answer. When a parent says that, what they’re really saying is, you’re not mature enough, old enough, smart enough, wise enough to understand or appreciate the answer. So for now, you’re just going to have to trust me when I tell you that I know what’s best for you.”
If that’s true for the relationship between a human parent and child, how could that not be infinitely more true for the relationship between our perfect, all-knowing, all-wise heavenly Father and us, his sinful, fallible, very imperfect and limited children? God says in Isaiah 55, “For my thoughts are not your thoughts, neither are your ways my ways, declares the LORD.”
Will you trust what’s in God’s Word? Because the most important thing it’s telling us this morning is… [Invitation.]
