Any attempt at predicting the end of the world is comical to me. The Apostles all thought that the return of Christ and the end of the world would come in their lifetime because Jesus told them that he would be returning soon, so they assumed that he meant before their death. Since then some pocket of every generation has believed that they would be the last generation and they Christ would return in their lifetime because of their interpretation of the signs of the end of the age foretold in the Bible. However, the Bible is very clear that we will not know it is going to happen. Christ himself made this very clear. He also made it clear that believers should be ever-ready for his return, so that they are not caught off guard when it happens.
The primary texts about the end of the world in the Bible come from the book of Daniel, the Gospels (Matthew, Make, Luke, and John), and Revelation. Christ spent a good deal of time talking about his return, the end of the world, and how to be ready right before he was crucified. He talked about the end of the world and the signs that would precede it, then he warned to be ready because the day and hour are unknown.
But about that day or hour no one knows, not even the angels in heaven, nor the Son,<sup class="footnote" value="[<a href="#fen-NIV-23994f" title="See footnote f">f</a>]">[

That is how it will be at the coming of the Son of Man. <sup class="versenum" id="en-NIV-23998">40</sup> Two men will be in the field; one will be taken and the other left. <sup class="versenum" id="en-NIV-23999">41</sup> Two women will be grinding with a hand mill; one will be taken and the other left. <sup class="versenum" id="en-NIV-24000">42</sup> “Therefore keep watch, because you do not know on what day your Lord will come. <sup class="versenum" id="en-NIV-24001">43</sup> But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. <sup class="versenum" id="en-NIV-24002">44</sup> So you also must be ready, because the Son of Man will come at an hour when you do not expect him.
Matthew 24:36-44 (NIV)
He then continues to warn about being ready so that when his return happens you will not be caught off guard and be left (all of this can be found in
Matthew 24-25).
I think that trying to interpret the signs of the end that are talked about in scripture is comical because these things have been happening for thousands of years. The "end times" are essentially the period of time leading up to the return of Christ and the end of the world. The period began 2000 years ago when Christ ascended into Heaven. Since we have been waiting for his return ever since we have been living in the end times. The entire period of history beginning after his ascension is the end times, because it is the period of waiting for his return. This is why it's ridiculous to try and predict when the end times will start or when his return will happen based on the signs because we are essentially already living in the end times, and the signs have been happening continuously for 2000 years. I think that these people are foolish and they give mainstream Christianity a bad name.
