One gripping and distinct feature of biblical Christianity is that it is forward-looking. God has spoken authoritatively about the future in His word, the Bible. Islam, Judaism, Buddhism, and other world religions each have their own doctrine of the future, but they are not as comprehensive and convincing, nor as fascinating and terrifying as the Bible’s teaching on the future. They all pale in comparison like a penny to a planet.

The word of God covers it all, like a reporter from the future. In the Bible, God tells us that there is life after death, that we must face Him in judgment, and that life will go on well after you take your final breath. But the Bible’s teaching on the future is not limited to eternity in heaven or hell—it also explains what God will do in the future to bring history to an end. God has a plan for the future. He will work in history to accomplish His purposes. The Bible tells us what will happen to us as individuals in eternity as well as what will happen to the world in history.

The branch of theology devoted to the study of the future is called eschatology. The Greek word eschatos means “last” or “end,” and eschatology is the study (the ology) of the end, or the study of the last things. Eschatology is the study of the Bible’s teaching on the future. When we study eschatology, we engage the plethora of biblical authors who were inspired by the Spirit of God, as He gave them “reports” about the future. We listen to John who was caught up in the Spirit when he penned the book of Revelation. We attend to the teachings of Peter, Paul, James, and Jude as God disclosed to them the events of the future by the inspiration of the Holy Spirit. And most importantly, we also hearken to Jesus, the eternal Lord, who told us what to expect in the future and in the life to come.

But why study eschatology? Why learn what the Bible teaches about the future? After all, isn’t eschatology confusing and only understood by scholars and pastors?

To be fair, eschatology can be confusing and it has certainly been muddied by years of misinterpretation and misrepresentation. Modern-day eschatology can be like a supreme pizza with too many toppings—nothing more than an unappealing mess. But it doesn’t have to be this way. You can clearly understand what the Bible teaches about the future through careful and faithful study. And here is why you ought to do so:

Reason #1: Because You Cannot Know the Future Without Eschatology

Human beings have memory of the past and awareness of the present, but we do not have the ability to foresee the future. You might have flashbacks, but you cannot have flashforwards. Precognition and perception of the future is reserved for Doctor Strange and the God of the Bible—and only one truly exists (sorry, Marvel fans). We may make reasonable predictions about the future based on patterns or natural order, but we do not inherently possess the ability to forecast future events with exact precision. Only God knows the future—He is omniscient or all-knowing. “He knows everything,” John wrote (1 John 3:20b). His understanding is beyond measure and He knows everything about everything. He is the author and possessor of the only infinite encyclopedia.

Thankfully for us, the God who knows the future (and ordained it) has revealed the events of the future, to some extent, in His word. God has disclosed in the Scriptures what are the grandiose eschatological events that will affect the entire universe, as well as what will happen to each individual person in eternity, based on their belief or rejection of Christ as Savior and Lord.

As Wayne Grudem aptly stated, “Although we cannot know everything about the future, God knows everything about the future and he has in Scripture told us about the major events yet to come in the history of the universe. About these events occurring we can have absolute confidence because God is never wrong and never lies.”¹

Reason #2: Because Eschatology Is in the Bible

You should study eschatology simply because it is biblical content. Everything in Scripture is profitable for the believer (2 Timothy 3:16-17) and that includes the doctrine of the future. True, nowhere in Scripture is it written, “Thou shalt study eschatology,” but this is one area of theology that you are specifically exhorted to get right.

That is what the apostle Paul implied in 1 Thessalonians 4:13-18. In this passage, Paul explained that death is only “sleep” for believers, since Christ will come again in a glorious return to “wake up” believers in resurrection. He dealt with the future in this text—eschatology. But notice how he prefaces the passage: “But we do not want you to be uninformed, brothers, about those who are asleep, that you may not grieve as others do who have no hope” (v. 13). Paul did not want the Thessalonians to be ignorant or uninformed about death, “the coming of the Lord,” and the resurrection when believers “will be caught up together with them in the clouds to meet the Lord in the air” (v. 15, 17). He wanted them to be informed as opposed to uninformed about futuristic events.

For Paul to say this means it is possible to be either informed or uninformed about eschatology. You can have the right information, the wrong information, or no information about the future. But you can and should be correctly informed. It is possible to possess correct knowledge about the future and it is expected that you do what is necessary to possess it.

Reason #3: Because False Ideas Abound

No area of theology is as rife with false ideas as eschatology (soteriology is a close second). Useless speculations and unbiblical propositions swarm the field of eschatology like a diamond ring in a public trash can—it’s hard to see the good stuff for the abundance of garbage. Shelves of misleading books have been published on the end times by those claiming to be evangelicals as well as liberal theologians who treat the Bible like Silly Putty, modifying it in anyway they want. And every year, dozens of new bizarre and bogus eschatological books fly off the press. You can count on it—if Israel fires a missile, if the United States votes for a new President, or if the moon burns red in an astronomical anomaly—someone will fill their pocket by releasing another phony volume on how the Bible supposedly predicts such matters.

Turn on the television and you’ll find a plethora of late-night prophetic “experts” whose only real expertise is falsehood. Jim Bakker promotes the sale of dehydrated and freeze-dried foods on his television program, since apparently the Bible prophesies a famine in the 21st century. Irvin Baxter, who hosts Understanding the Endtime, teaches on his one-hour program that the Bible mentions the United States, the tearing down of the Berlin Wall, and other biblical prophecies which are being fulfilled before our eyes by current events. During It’s Supernatural, host Sid Roth interviews guests who have visited heaven in near-death experiences and crazed charismatics who claim God spoke directly to them about how Russia will lead the way to the New World Order.

These dangerous wolves and their deadly ideas will remain abundant since they have convenient explanations for a confusing subject. And they will continue to have a bounty of material since there will always be wars, earthquakes, planetary phenomena, and technological advancements.

The temptation to be deceived and the susceptibility to circumvent biblical truth is especially prevalent in the study of eschatology, since it is sometimes puzzling and complex. By the way, if we believe that we are exempt from deception in our own eschatology, then we carelessly assume that we are better than the Thessalonians and need no warning from the apostle Paul! He wrote to them: “Now concerning the coming of our Lord Jesus Christ and our being gathered together to him, we ask you, brothers, not to be quickly shaken in mind or alarmed, either by a spirit or a spoken word, or a letter seeming to be from us, to the effect that the day of the Lord has come. Let no one deceive you in any way” (2 Thessalonians 2:1-3a). He did not want them to be unsettled or deceived in their thinking about the second coming and eschatological events—which means it is possible to be deceived and unsettled.

The final and only authoritative word on the second coming, the end times, and the future is the word of God. The way to determine if a stick is crooked is to lay a straight one beside it—and studying the Bible’s teaching on eschatology is the only way to avoid crooked deception. Proper interpretation will prevent you from falling into parlous deception (or it may rescue you from it).

Reason #4: Because Clarity is Possible and Confusion is Avoidable

Many people drive past the study of eschatology because it appears to be complicated and baffling. Unfortunately, eschatology has been understood as nothing more than perplexing charts, heated arguments, endless “isms,” and biblical math. This is a serious underestimation, to say the least, for biblical eschatology is so much more.

Certainly, God is not responsible for the confusion that has infiltrated eschatology. He is not the author of confusion and His word is clear and understandable (1 Corinthians 14:33). The responsible party for confusion, then, must be sinful and fallible men.

Why, then, is eschatology sometimes unsettling and confusing? Here’s how I see it: on The Price is Right, each audience member shouts a different answer to help the contestant make the right call on the value of an item. But it’s nothing more than annoying noise because of the abundance of answers. Does that mean there is no correct answer? No, but it makes it difficult—nearly impossible—to discern the right answer. Likewise, understanding what the Bible truly teaches about the future is challenging because everyone is shouting different answers—but that doesn’t mean the right answer is undiscoverable.

Again, Paul implied in 1 Thessalonians 4 that you can have the right biblical information about the future. And he also implied in 2 Thessalonians 2 that it is possible not to be deceived regarding eschatological matters. A biblical and thoroughly correct understanding of eschatology is attainable. The study of eschatology is definitely demanding and difficult, but it does not have to be disorienting. The right answer is out there—the difficulty lies in muting those who shout the wrong answers.

Reason #5: Because Eschatology Affects Your Life in the Present

“I’ll be by your office between 9 and 10 this morning,” a church member assured. Did they mean 9:15 or 9:59? Well, I didn’t have that information. All I knew is that they would visit me in the near future. And I conducted myself accordingly by waiting for them by the church door. What I knew about the future affected what I did in the present.

When you learn and discover what the Bible says about the future, your life in the present is directly impacted. What you do today is always governed by what you know will happen tomorrow. And when you know for certain, for instance, that Christ will visit the earth again in glory and judgment (as the Bible teaches), you will stand by the door in anticipation! His second appearance is guaranteed, unavoidable, drawing nearer, and no man knows the day or hour when it will be (Matthew 24:36). Knowing this truth about the future compels you to do something about it now.

Eschatology enables faithfulness in the present. As John Frame wrote, “So far as I can see, every Bible passage about the return of Christ is written for a practical purpose—not to help us to develop a theory of history, but to motivate our obedience.”² The promise of a new heavens and new earth encourages you to abandon worldliness. The reality of belonging to the kingdom of God now prevents a toxic obsession with the affairs of earthly kingdoms and nations. The certainty of impending (and ongoing) state-sponsored persecution of the church compels you to stick close with the local church, in preparation to suffer and die together. What is done in the present is determined by what is to come in the future (at least, it ought to be).

I’ve often heard, “Why concern myself with what’s going to happen in the future? What’s gonna happen is gonna happen, so shouldn’t we focus instead on evangelism, Christian living, and figuring out how to grow closer to God?” Interestingly, biblical eschatology is what provides clarity and perspective on all those crucial matters. Eschatology fills the fuel tank of passion in evangelism. Eschatology keeps you glued to the right path. And nothing will compel you to grow closer to God than knowing that the day of the Lord grows closer (which is eschatology). Eschatology may be concerned with the then, but it is certainly for the now.

Reason #6: Because You Cannot Prepare for the Future Without Eschatology

You can’t prepare for something if you don’t know it’s coming. If I had no knowledge of my church member’s intent to fellowship in my office that morning—I might have missed an important visit. If you missed the emergency weather warnings on the morning news, you may get caught in a tornado on your way to work. If you toss a summons from the courthouse that states that on such-and-such date you are to appear in court for a speeding ticket, you may end up paying more than a small fine!

If you do not know that Christ is coming again, you may be on the wrong side of the most important visit in history. If you miss the warnings in Scripture about the storm of God’s wrath that Christ will unleash at His Parousia, you will get caught in more than a tornado. If you ignore the clear statements in the Bible that you will be judged on the Final Day, you will pay more than you could ever imagine.

You must know eschatology to be prepared for the redemptive events of the future. But conversely, you need biblical eschatology to avoid preparing for something that will never happen. Many believe credit cards and vaccines are the mark of the beast. More believe that Joe Biden is the antichrist (like literally every other United States President). And some hold that the moving of the United States embassy to Jerusalem is an undeniable sign of the end. Here’s the bottom line: your heart won’t wander into these endless and meaningless speculations about the future when you are firmly planted in the Scripture’s teaching on the future.

Reason #7: Because Eschatology is Encouraging

As stated earlier, it is lamentable that eschatology has been reduced to a puzzle of confusion. This grave miscalculation of the value of biblical eschatology has caused many Christians to forfeit one of its most rewarding benefits: encouragement. Surprisingly, it is eschatology that will lift your head and lighten your heart. Tell me—what is more encouraging than knowing that Jesus is coming to earth to bring grace and reward? What is more encouraging than knowing Christ will come again to usher in a new heavens and new earth? What is more encouraging than knowing He will transform your lowly body and gather you unto Himself?

When you are troubled with guilt, study eschatology—it tells you that you will be guiltless on the day of Christ’s coming (1 Thessalonians 3:11-13). When you are weary of this present world and physically afflicted with bodily aliments, study eschatology. It assures you that the Savior will “transform [your] lowly body to be like his glorious body, by the power that enables him even to subject all things to himself” (Philippians 3:20). When you are exhausted from grief, study eschatology. It reveals that Christ will bring heaven to earth for every believer and, “He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away” (Revelation 21:4). When seeking things above and living for the kingdom becomes burdensome, study eschatology. It proclaims that such faithfulness is worth it because, “When Christ who is your life appears, then you also will appear with him in glory” (Colossians 3:4).

Conclusion

How can you get started in your study of eschatology? There will be more on this later. This is only the first of many forthcoming posts in a series on biblical eschatology. To the best of my ability, I will cover it all right here on the blog. I will discuss the central eschatological passages in Scripture, interact with all the main viewpoints, and discuss topics like the rapture, the great tribulation, the antichrist, Israel and the church, the kingdom of God, the millennial reign of Christ, and much more. But if you want to get started studying eschatology, I recommend reading The Bible and the Future by Anthony Hoekema, Kingdom Come by Sam Storms, A Case for Amillennialism by Kim Riddlebarger, and The Presence of the Future by George Ladd. For works more systematic and more appropriate for study, see the volumes Systematic Theology by John Frame and The Christian Faith by Michael Horton.
