Wow! Is it really possible for people to know for sure when Jesus will return? We'll kee this answer short and simple, because that's exactly what Jesus did when He was teaching about this topic. In fact, His teaching on this matter was so straightforward, so clear, that I'm just going to share His words with you. Here is what Jesus said about His future return:
“No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. As it was in the days of Noah, so it will be at the coming of the Son of Man. For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. Two men will be in the field; one will be taken and the other left. Two women will be grinding with a hand mill; one will be taken and the other left.
“Therefore keep watch, because you do not know on what day your Lord will come. 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. 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)
So, lets recap. Jesus made it clear that NO ONE knows when He is going to return. NO ONE. That includes this group which claims they know. They may have cool t-shirts, crazy billboards, and awesome RV's (I want to take a vacation with one of those RV's!) but they don't know. In fact, Jesus doesn't make a big deal about the WHEN, He makes a big deal about being ready! So, that begs the question: Are you ready for Jesus to return? He is coming.
