Odd Wolf – Sermon on Matthew 7:15-23 for the Eighth Sunday after Trinity

Matthew 7:15-23

In the name of Jesus. Amen.

We live in a dangerous world. Because sin and death have entered God’s good creation, there are all sorts of things that can harm you. You could get hit by a drunk driver on the way home. A lunatic could shoot and kill you at the grocery store. Smoke from wildfires can do damage to your lungs. An asteroid could fall from the sky. But Jesus doesn’t tell you to beware of any of those things. The reason Jesus doesn’t warn you about those things isn’t that He is naïve and thinks they are harmless. Rather, He doesn’t warn you about them because they can only temporarily harm you. Christ does warn you—and it’s a stern warning—against false prophets.

Don’t get the wrong idea about these false prophets. A prophet isn’t only someone who predicts the future. Isaiah, Jeremiah, Ezekiel, and Daniel were all prophets who spoke accurately about things that were still in the future. King David was a prophet when he wrote about Christ’s death, resurrection, and rule in many of the Psalms. They did that because they were inspired by the Holy Spirit to declare God’s Word. And sometimes, that Word dealt with things that were still to come. But the Bible also gives the title of prophet to those who publicly preach and teach God’s Word (Act. 15:321 Co. 14:1329-32). That is what Jesus is referring to here when He warns against false prophets. They are people who preach and teach God’s Word, but they do it falsely.

Jesus describes these false prophets as ravenous wolves who dress up in sheep’s clothing. It’s a stern warning. It’s a solemn warning. It’s right up there among the most dire warnings that Jesus speaks in all of Scripture. As serious as this warning is, we should find comfort even in the warning. Let me explain that first, then we’ll get to the warning.

Imagine you were sick. You’re in pain. Your strength keeps declining as you become more and more lethargic. Your body is slowly shutting down. You’ve tried all sorts of things, but none of them work. Doctor after doctor can’t figure out what’s wrong. You know that if this sickness keeps progressing, it’ll kill you. Imagine you finally went to a doctor who had the answer. He diagnoses your illness perfectly, gives you a prescription, and it works. After the first dose, the sickness is gone. Your energy returns. You get back to normal. You go back to that doctor for a follow-up.

He is pleased after he looks at your vitals, sees how well you’re doing, and is delighted. Then the doctor’s face becomes utterly serious. He looks intently at you and says, “Listen to me. Don’t ever stop taking this medicine. Never miss a single dose. Take it exactly as I’ve prescribed it to you. If you ever stop taking it, you’ll die. If anyone tries to tell you about another remedy, they’re wrong. This is the only cure. I’ll always make sure you have it for free. No cost to you ever, but you need to keep taking it.”

Now, would that warning from the doctor be good or bad news? Of course it’s good news. There’s medicine that keeps you healthy, and it’s free. That’s the way we should hear Jesus’ warning against these false prophets. Yes, it’s a stern, sober warning. But it also means that there are true prophets and shepherds who give the medicine of immortality for free.

As you receive the free medicine of the Gospel, beware of false prophets. Beware of the ravenous wolves who would lure you away from this Gospel. They are the most serious danger you face, Christian.

Jesus tells you why they’re dangerous. Sure, Jesus calls them ‘ravenous,’ but that isn’t what makes these wolves a threat to you. The danger isn’t in their sharp teeth and powerful jaws. It isn’t their speed and strength. No, the wolves Jesus warns against are strange. They are odd wolves.

This might sound a little silly but, as I studied this text this week, I kept thinking of children’s stories. I first thought about “The Three Little Pigs.” In that story, the wolf is dangerous because he huffs, puffs, and blows the houses of straw and sticks down. I don’t know for sure, but I don’t think wolves are known for their lung capacity. That wolf at least warns before he comes after the pigs.

Then I thought of “Little Red Riding Hood.” In that story, the wolf doesn’t barge in the door or announce himself with a roar. Instead, he puts on the grandmother’s nightgown, pulls the cap over his ears, softens his voice, and climbs into the bed. For Little Red, the most dangerous thing in the room looked and sounded like the safest person she knew.

That’s the kind of wolf Jesus warns about here. What makes these wolves dangerous is their deception. They come disguised in sheep’s clothing. The wolves who will destroy you look like sheep. They sound right. They will talk about Jesus. They can quote the Bible. They may even do mighty works in Christ’s name (Mt 7:22). The danger is not their strength. The danger is their clothing. 

If these false prophets came to you and looked like a wolf, you would run. If they came preaching open blasphemy, you would barricade the door. But that’s not how they come. They come dressed as a Christian teacher. They appear with a Bible in their hand and a smile on their face. These false prophets come saying things that sound almost right. That is how they get into the house.

Jeremiah warned about the same thing centuries earlier in our Old Testament reading (Jer. 23:16-29). The false prophets of his day did not stand up and say, “Forget about Yahweh,” or, “Follow these other gods.” No! They sounded nice. They softened God’s Law. They proclaimed false things to sinners. “Everything will be fine, and no disaster will come upon you” (Jer 23:17). They spoke visions of their own minds and called it the Word of the Lord. They filled the unrepentant people with false hopes and false comforts. And, sadly, the people listened, because the message felt safe, soft, and comforting. Like a grandmother’s voice. We face the same deception.

But Jesus tells us how to spot the difference. Christ gives us one test: “You will recognize them by their fruits” (Mt 7:16). You don’t recognize them by their personality, by how nice they are, or even by whether they can quote Scripture. Remember, the devil himself used Scripture when he tempted our Lord in the wilderness (Mt. 4:1-11).

According to Jesus, you spot these false prophets by their fruits. The fruit of a prophet is his teaching—just like the fruit of a baker is the bread he bakes, or the fruit of a doctor is the healing he brings. For anyone who prophesies—anyone who proclaims God’s Word—you have to ask two questions: First, “Does this point out where I have sinned? Does it faithfully proclaim that I am a sinner in need of God’s grace and mercy?” Or, “Does this tell me that God loves me and others just the way we are without any repentance?” The second question to ask is, “Does this point me to Christ crucified and risen, freely, without my works?” Or, “Does this put the weight back on my shoulders? Am I being told that my salvation depends on me putting in a little more effort or sincerity or a few more good works?”

Jesus says that a healthy tree cannot bear bad fruit, and a diseased tree cannot bear good fruit (Mt 7:18). In other words, the teaching will eventually show itself. But you need to know the real thing well enough to compare.

That is why Christ keeps driving us back to the Scriptures. That is why studying the Bible is not just some optional busy-work. You can’t turn off your ears and mind the moment a sermon starts. Jesus is calling you to be fruit inspectors. Not because you are smarter than everyone else, but because the wolves are that good at disguise.

God’s Word doesn’t always flatter you. It doesn’t always say, “Peace, peace,” because there isn’t always peace (Jer. 6:148:11Ezk. 13:13). Scripture isn’t always pleasant. It isn’t always what you want to hear. God’s Word kills our old, sinful nature so that it can make us alive. It shows you the wolf and then points you to the only refuge—Christ Himself.

Whenever someone claims to proclaim God’s Word, be suspicious. Watch for red flags. That discernment is a good work that Jesus gives you to do today and every day.

Be wary of every teacher and preacher—including the one standing in this pulpit. Don’t just trust me because I’m so smart, handsome, and friendly. (I’m not much of any of those things.) Test the teaching. Compare it to the Scriptures. Hold fast to God’s Word. See the goodness of His Law. And cling to the Gospel—the full, free forgiveness of sins that the Gospel delivers to you. Build on that.

The wolves are always out there in their soft, wooly, sheepish disguise. But the Good Shepherd has already laid down His life for you, His sheep. His voice, His Word, is what will keep you safe now and for eternity. Amen.

The peace of God, which surpasses all understanding, will guard your hearts and minds in Christ Jesus (Php. 4:7). Amen.

Discern – Sermon on Romans 12:1-5 for the First Sunday after Epiphany

Romans 12:1–5

1 I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. 2 Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. 

3 For by the grace given to me I say to everyone among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned. 4 For as in one body we have many members, and the members do not all have the same function, 5 so we, though many, are one body in Christ, and individually members one of another.

In the name of Jesus. Amen.

You will be changed. Please note how that was worded. It isn’t, “You will change,” even though that’s true. It wasn’t, “You must change,” as though this is all up to you. According to this text, you will be (passively) changed. Here, you are given a passive command, which we can’t really translate well into English. What we have there in v. 2 could be translated, “Do not become conformed to this world, rather become transformed by the renewal of your mind.”

In other words, there are things that are going to mold, shape, and change you. But there are some things that should not do that, and there are some things that should.

First, don’t allow the world to change you. The word there is, actually, ‘age.’ “Do not become conformed to this age.” This age isn’t only this world; it’s also the demons, forces of evil, and the culture that pull on you. Our age seeks to conform you to itself. We’ll talk about things like peer pressure and, maybe, even societal pressure. We are to resist those. But we are also to resist the demonic pressure and self-imposed pressure to fit in with this evil age. All those things of this age try to press, pull, form, and mold you like you’re Silly Putty. 

Hopefully, enough of you have played with Silly Putty for this analogy to work. You can easily make Silly Putty do all sorts of things. My siblings, cousins, and I would play with Silly Putty at my grandparents’ home in Faith, SD. We’d take it out of the red egg container and roll it into a bouncy-ball and play catch. When we got tired of that, we’d smoosh the puddy into a flat oval, press it onto the newspaper ink, peel it off, and stretch out the letters and pictures left on the putty. You can make Charlie Brown’s head look even more ridiculous with a blob of Silly Putty. When we got tired of manipulating a particular smudge of ink, all we had to do was simply push, roll, and re-flatten the putty, and it was ready to do another one. The ink from each image never actually left the putty; instead, it just got absorbed into it.

A lot of Christians have allowed this age to work on them like putty. And there are all sorts of reasons they allow it. Maybe they don’t want to be laughed at, so they’ll go along with the theory of evolution and try to make it fit with the account of creation. It doesn’t. It can’t, but they try anyway. Maybe they don’t want to be considered a fundamentalist, so they will compromise on all sorts of things like marriage, sexuality, abortion, and whatever. Here, Paul says, “Don’t. Don’t do that!”

When you allow this age to press and pull and stretch you in different ways, you are in a dangerous place. Just like I’d get bored bouncing a Silly Putty ball around, this age will try to conform you into all sorts of things for all sorts of uses. And just like the ink never really leaves a blob of putty, some of the ways this age will play around with you will stick with you your entire life. Christian, don’t let this age play around with you as though you’re a blob of Silly Putty.

I just need to add here: This world does change you in ways that are fine. There are plenty of lessons to learn from people and organizations that aren’t necessarily Christian, but be careful with them. Have your filter up. Keep in mind what Php. 4:8 says, “Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.”

All that being said, you are to allow change to come from other places. “Be transformed by the renewal of your mind.” What does that mean? We might wish that Paul had said, “Be transformed by keeping the Ten Commandments,” or, “Be transformed by praying at such-and-such a time.” That would be a lot easier to understand and do. But that’s not what Scripture says here. You aren’t given a set of instructions to do or accomplish. Instead, you’re given the result of this transforming. This transforming results in the renewal of your mind, and it results in an ability to discern the will of God. God wants you, as time goes by, to get better and better at testing and figuring out His will, which is good, acceptable, and perfect/complete.

Sometimes, we’ll talk about the Ten Commandments as God’s will, what He desires us to do. And that is true. God’s will is that you have no other gods, use His name rightly, keep the Sabbath, honor your parents, not kill, not commit adultery or steal or lie or covet. That’s God’s will – plain as day. But none of that takes discernment to figure out. God has clearly said it. “Thou shalt not murder.” When you get angry at someone and want to harm them, you don’t have to discern if you should or not. Don’t do it!

When Scripture says here that you should allow yourself to be transformed so that you can discern God’s will, it’s saying that there are times when God’s will is for you to do something or not do something, but He hasn’t clearly, explicitly said what His will is. Instead, you’re going to have to discern what you should do. Yes, the Commandments are there to help and guide you, but the Commandments don’t address every decision you have to make day by day.

For example. Let’s say your kids are behaving poorly. What should you do? There isn’t a Commandment that definitively addresses that. So, should you discipline them and make sure they feel your wrath? Do you go by Pro. 13:14, “Whoever spares the rod hates his son, but he who loves him is diligent to discipline him”? Maybe. That might be the most godly, loving thing you can do. Or, should you be patient with your kids? Should you follow Col. 3:21, “Do not exasperate your children, lest they become discouraged”? Should you pause, take a step back, patiently talk with them, try to understand what’s going on? Again, maybe. That might the godly, right thing to do.

How do you know which to pick – discipline or patience? The Bible says both are good. How do you navigate it? God has a will for that situation, but He hasn’t explicitly spelled it out in the Bible. God hasn’t said, “When thy child flips out after you deny their request for candy at Hugo’s in East Grand at 12:34 PM on Jan. 12th, 2025, here’s how you handle it. But if it’s at Ace Hardware, here’s how you handle it.” God has ways He wants you to live, but it might be difficult to know how to handle each particular situation that comes up moment by moment, day by day.

Should you give money to that person on the corner by Sam’s Club? Should you watch that show or movie? Here’s a good one: Should you engage with that comment on social media? Ha! Proverbs 26:4 says, “Answer not a fool according to his folly, lest you be like him yourself.” But in the very next verse, the Bible says, “Answer a fool according to his folly, lest he be wise in his own eyes.” You’ve got two verses back-to-back saying, “Don’t do it,” and, “Do it.” So, how do you know what to do?

I can’t tell you. No one can. In His wisdom, God has made these decisions challenging for us and require us to grapple and test and discern what we are to do. In other words, God wants us to do the difficult work of gaining and growing in wisdom. This is what it is to be transformed by the renewal of your mind. This renewal of your mind happens as you read the Bible. The Holy Spirit takes God’s Word and works on you, renewing and transforming you into what He wants you to be.

2 Tim. 3:16-17 says that all Scripture is inspired by God and is there to train you in righteousness that you may be complete, equipped for every good work. In other words, the Bible trains you and renews your thinking and mind. It transforms you. More and more, as time goes on, you are to be filled with God’s Word and bring it to bear in the decisions that are constantly coming at you each day.

This doesn’t mean you have to listen for a voice from heaven and have God directly speak to you. No. Don’t expect God to spell it out like that because that doesn’t take any work. Again, in His wisdom, God has made this more difficult, but that struggle is good for you and for me.

God wants this to be the rhythm of your life. Go about your life, make those decisions, and read the Scriptures. Evaluate how you made those decisions. Maybe, you’ll realize that you did poorly and didn’t do God’s will. Then, repent. Receive God’s forgiveness for that sin. Learn from your mistake. Do better the next time.

Maybe, you’ll realize you did well and that experience will make you better equipped to handle an even tougher decision in the future.

Then, armed with that experience and filled with wisdom from God’s Word, go, live a bit more. Make more decisions, and return again to the Scriptures. Live. Read the Bible. Live. Read. Constantly weave your life and God’s Word together. That work leads to godly discernment. It transforms and renews your mind.

Know that this transforming doesn’t happen very well if the only time you hear the Scriptures is when you’re here at church. Discerning God’s will is a life-long process. It takes work. But don’t forget that this is good work, and it is how God wants to be about His business of continually transforming you. And He isn’t treating you like a blob of Silly Putty. He’s sculpting you, or, even better, He’s metamorphosizing (that’s the word here translated ‘transform’) you into a living sacrifice that is holy and acceptable to God (Ro. 12:1).

Finally, I want to make sure we anchor all of this to the context – both of this passage and the whole book of Romans. Remember this is an appeal, an appeal that is based on the mercies of God. In other words, only Christians who have been freely and completely forgiven of their sins because of what Christ has done – only they can be transformed in this way.

Even with all the discernment you gain from God’s Word, even with a mind that is filled with biblical wisdom, there will be times where you fail to do God’s good, acceptable, perfect will. That’s when you flee again to His mercies, which are new every morning (Lam. 3:22-23). And remember what Scripture said just a few chapters earlier in Ro. 8:1, “There is therefore now no condemnation for those who are in Christ Jesus.” None. Zip. Zilch. Nada. No condemnation.

Yes, grow and be changed by God’s Word. Don’t be conformed to this age. Instead, grow in wisdom, be metamorphosized, and discern. And always know and trust that Christ’s mercy covers you, now and forever. Amen.

The peace of God, which surpasses all understanding, will guard your hearts and minds in Christ Jesus. Amen.
