The study of Eschatology in the church is usually met with two distinct responses. On the one hand, some become so consumed with an over fascination that it drives them to unhealthy speculations, and on the other hand, others are so filled with apathy and distaste that they would rather neglect its doctrines altogether. Recently, I heard about one church that spent eighteen months studying the Book of Revelation, and there is nothing wrong with that per se. However, to the external observer, it could appear as if this subject is more important than the Gospel itself. This is perhaps part of the reason why this area of theological reflection is so often met with such varied and disparate responses; we have failed to demonstrate clearly how these truths are connected to the saving work that God has accomplished in and through His Son, Jesus Christ. We have become so bogged down in controversial matters like tribulations, raptures, millenniums, antichrists, and the like, that we have lost the point that these events bring the promises of the Gospel to completion.

At its core, the Gospel is about how God has solved, is solving, and will solve the problem of sin. Of course, sin is first and foremost a personal individual problem; human beings are corrupted by and enslaved to sin, and because of this, they deserve to spend eternity in hell under the wrath of God. However, in the Gospel, Jesus Christ took upon himself the punishment that we deserve; He died in our place, satisfied the wrath of God, and declared, “It is finished!” Now, by grace through faith in Him, we are forgiven of our sin, clothed in His righteousness, and promised eternal life. But sin is also a cosmic problem, because all of creation has been polluted by and cursed because of sin. As the Scriptures explain,

For the creation eagerly waits with anticipation for God’s sons to be revealed. For the creation was subjected to futility—not willingly, but because of him who subjected it—in the hope that the creation itself will also be set free from the bondage to decay into the glorious freedom of God’s children. 

~Romans 8.19-21

In the beginning, when God created the world, all was very good, but with the fall of mankind, sin and its consequences have hopelessly poisoned God’s good creation. This world reeks with the stench of death and decay; where there was once life and beauty, there is now sickness and death. But in the gospel, God is making all things new; he is restoring and recreating the paradise that was lost. In the Book of Revelation, chapters 21-22, we read of a new heaven and new earth which is completely free of sickness and death, heartache and pain, tear and loss. It is a world that is completely free from the stain of sin in every way. It is not just the Garden of Eden restored, it is the Garden of Eden made better.

In other words, the Gospel is inherently and irreducibly eschatological, because not only have we been set free from the penalty of sin, not only are we being set free from the power of sin, but one day we will be set free from the very presence of sin. Until then, we live in the tension of the already but not yet, already forgiven of our sin, already free from sin’s tyranny, but not yet free from its temptations and habituations in our daily lives. We rightly long for the day when the problem of sin and its effects will be no more; this is our blessed hope. And this is why the study of Eschatology should not be viewed as a distraction from the proclamation of the Gospel. On the contrary, the doctrines of Eschatology are so intricately and intimately woven into the fabric of the Gospel, that if we neglect or ignore them, we truncate the Gospel message, empty it of its power, misconstrue the nature of its promises.

This is not to say that the study of Eschatology is always done correctly. Certainly, there are many who have engaged this subject matter in improper or unhealthy ways that have shifted the focus or missed the mark. Eschatology is one of those areas in the study of which it is possible to miss the forest for the trees. There are many details and questions that fall into this category that could become a distraction. However, this does not mean that we should omit the study of it altogether, because Eschatology is fundamentally about hope, the hope of a world free from sin. This is the wonder of our salvation, not only that we have been forgiven of our sin and have received eternal life, but that the work of Christ in salvation has put something into motion that will completely transform the world as we know it.

For the grace of God has appeared, bringing salvation for all people, instructing us to deny godlessness and worldly lusts and to live in a sensible, righteous, and godly way in the present age, while we wait for the blessed hope, the appearing of the glory of our great God and Savior, Jesus Christ.

~Titus 2.11-13
