Many Christians have often wondered how the world will end. Is it through massive earthquakes and volcanic eruptions? An asteroid colliding with our planet? Or the fulfilment of the biblical Rapture when Christian believers are suddenly removed from the Earth before the second coming of Christ?

A newly released book may provide answers to this question.

Seeking to give clarity to a subject that has been debated for so many years, Billy Hallowell, faith editor for multiplatform news and entertainment network "The Blaze," came out with a book called "The Armageddon Code: One Journalist's Quest for End-Times Answers."

As the title of the book suggests, Hallowell attempts to give comprehensive answers to questions on the apocalypse that have been racking Christians' minds for centuries.

"We wanted to create something, a book that was different from the other books that were out there on the market by giving every single belief system involved in sort of the Protestant realm a fair game and a fair chance to be heard," Hallowell told CBN News.

To be able to do this, the faith editor interviewed 20 Christian ministry leaders who have extensive knowledge on what the Holy Bible says about the End Times. He also conducted a survey of 1,000 pastors for the book.

The book contains chapters on possible causes and signs of the Apocalypse, including the mysterious Antichrist.

"The way that this is laid out is it tackles each piece—the Rapture, the tribulation period, the millennium. It goes into the Antichrist—the different views about the Antichrist," Hallowell explained.

To be able to give a comprehensive view on how faith leaders perceive the end of the world, Hallowell also took a step back into history.

"We get into Israel, which really is just the most fascinating I think in the book, the topic of Israel and 1948 and the regathering of Israel," he said. "And then going into date setting and why Christians shouldn't be setting dates."

The book's ultimate goal, Hallowell said, is to help Christians understand their faith even more.

"It's like reading a conversation on this topic, which so rarely is done," Hallowell said. "I think so much of the time when we talk about this—which is fine and great—we hear it from pastors and theologians, and it's that one perspective."

"But I think this helps us understand what do Christians believe, why do they believe it and get a broader sense of that," he said.
