Matthew 7:15-23
15 [Jesus says,] “Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. 16 You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? 17 So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. 18 A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus you will recognize them by their fruits.
21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. 22 On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ 23 And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’”
In the name of Jesus. Amen.
Christian, the greatest danger you face is not a virus, riots, or any natural or manmade disaster. The greatest danger to a Christian is not politicians, persecution, or even martyrdom. The greatest danger you face, dear Christian, is false teaching. The worst any of those other things could do is send you to be with your Savior. But false teaching from false prophets, who are ravenous wolves, can lead you to eternal hell.
I came across an illustration that is based on a true story: There was a train operating during a severe blizzard, and the spaces between the stops for this train were empty, barren country. A woman was on that train with her infant child and was very nervous about the whiteout conditions. Whenever the train would stop, she would ask the conductor if she was supposed to get off. She couldn’t tell by looking out the window because it was storming too hard.
This happened several times. The train would stop, and the woman would ask the conductor, “Are you sure this isn’t my stop?” “No, mam. This isn’t it.” After this happened a couple more times, and the conductor reassured the woman, “No, this still isn’t your stop, but when we do get to your stop, I’ll come and let you know. I’ll make sure you get off when it’s time.” The train went on and stopped a few more times, when a man in a seat near the woman leaned over to her and said, “We’re at your stop.” And the woman hesitated, “But, the conductor told me he would come and let me know.” The man replied, “It’s ok. He must have had to take care of something else. I’ve been riding this train for years. I heard where we were two stops ago, and trust me, this is your stop.” So, the woman grabbed her things, carried her infant to the door, and stepped off into the blizzard.
The train started again and eventually came to another stop. The conductor walked to the seat where the woman had been, but as he looked around the woman wasn’t there. So, the conductor asked the man, “Where’s the woman and her baby?” The man said, “Don’t worry. I took care of it for you. Even though you missed it, I let her know the last stop was hers. She got to her destination.”
The conductor shouted, “You told her to get off! The last time the train stopped wasn’t at a station. We had to stop in the middle of nowhere because of snow on the tracks!” They immediately threw the train in reverse and went back. But when they got there it was too late. They found the woman holding her baby, and both were frozen to death. That woman and her child needlessly died because of bad information from a well-intentioned individual who was simply wrong.
Dear saints, that story has a lot to say about the last paragraph of this Gospel text. According to Jesus, there are those who have all the appearances of being genuine and biblically informed. They will refer to Jesus as Lord. They will teach and prophesy in Jesus’ name. They will do many mighty works claiming the power of Jesus. But when they stand before Christ on the Last Day, they will hear Jesus say, “I never knew you; depart from me, you workers of lawlessness.”
On that day, many will be shown to be false teachers and false prophets. Even though they seem to be knowledgeable and can to point to a high worship attendance, their impressive buildings, and their many podcast downloads and views of YouTube, it won’t matter. Numbers and statistics are meaningless to Christ. The only thing that matters is if that teacher faithfully preached Jesus Christ and Him crucified.
Now, good intentions but bad information is one thing. But Jesus also warns us about false prophets who come in sheep’s clothing but inwardly are ravenous wolves. Dear saints, Jesus cautions us that there are those who intentionally lead people astray into false theology and doctrine.
It has been said that the most common command in Scripture is to not fear, and that’s probably true. There is nothing that we need to fear except God alone. But the Scriptures do a lot of warning when it comes to false doctrine and teaching. And you have heard some of that in our readings today. This Gospel text is filled with Jesus’ own words warning against false, misleading teaching. Our Old Testament lesson (Jer. 23:16-29) was also a lengthy diatribe on the dangers of false prophets and the ruin that they bring instead of the preaching of repentance that God wants His people to hear. And the Scriptural warnings don’t stop there.
1 Timothy 4:1 says, “Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons.” Did you catch that? Some “will depart from the faith” – that means Christians will stop believing in Jesus for the forgiveness of their sins. And in the place of the Gospel, those people will devote themselves to deceitful spirits and the teachings of demons.
In 2 Peter 2:1, Peter recounts how false prophets arose in the past and goes on to say, “[T]here will be,” notice this isn’t just a hypothetical, “there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Master who bought them, bringing upon themselves swift destruction.”
In Acts 20:17-35, Paul says his final goodbye to the leaders of the church in Ephesus. Paul had been pastor there for three years (Act. 20:31), but he knows that he won’t see them again. So, Paul spends his last moments with these believers warning them about the danger of false teachers. He says, “I know that after my departure fierce wolves will come in among you, not sparing the flock; and from among your own selves will arise men speaking twisted things, to draw away the disciples after them. Therefore be alert” (Act. 20:29-31).
Dear saints, you need to be alert. When Jesus says, “Beware of false prophets,” Your Savior is giving you a command. Again, there is no need to fear but you do need to beware, and Jesus gives you a sure way to detect when ravenous wolves and even good-intended people teach falsely in His name. You will know them by the fruit of their teaching. Any teaching that does not ultimately point you to Jesus’ work of purchasing your forgiveness by His death and resurrection is bad fruit that comes from the thorns, thistles, and bad trees of false doctrine.
The best way to recognize the bad fruit of ravenous wolves and those who are well-intentioned but misguided is to know good theology yourself. That means – know your Bible. Be in the Word. Read it. Study it. Immerse yourself in it every chance you get. Check the sermons and theology you hear – even from this pulpit and this mouth – with what the Bible says. If you hear me preach or teach something that doesn’t line up with what Scripture says, call me out. And if I can’t back it up from the Bible, run me out of here.
And, parents, train your children in the Word of God. Teach them the Bible stories. Constantly point them to Jesus for the forgiveness of sins. Help them memorize the Catechism. It teaches the main doctrinal truths of the Bible and has stood the Scriptural test for 500 years. We will be starting Sunday School and Confirmation again in a little more than a month, and, as a congregation, we are to help you teach the Bible to your children. But don’t think for one second that coming to church and Sunday School for two hours a week is enough Bible for your kids. Your kids need to see you model the importance of studying the Scriptures.
Dear saints, Jesus is everything. Without Christ’s death, resurrection, and forgiveness, nothing else matters. In Jesus is life, eternal life. He has done what was necessary to deliver you from sin, death, and the devil. Because of what He has done, you can walk through the valley of the shadow of death fearing no evil because He promises to be with you (Ps. 23:4).
And, ultimately, take comfort. Jesus tells us to beware false teachers and their hellish doctrines, but He also makes a promise. Just after this text, Jesus concludes the Sermon on the Mount by saying, “Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock” (Mt. 7:24-25).
May this be true of us all as we stand firm upon the sure and certain promises of our Lord. Amen.
The peace of God, which surpasses all understanding, will guard your hearts and minds in Christ Jesus. Amen.
Beware. Do the Scriptures teach, as Roman Catholics believe, that when the pope speaks officially, his words have the same authority as the Scriptures? No. Does the Bible say, as Methodists teach, that Christians reach a point where they no longer sin? No. Does God’s Word say, as many churches say today, that baptism is the first act of obedience of a Christian? No.
You need the good fruit of God’s Word. It is your source of life. It is your nourishment that sustains you in this life and the next. Pluck that good fruit from the cross which has become the tree of life.
