“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

Throughout history, people have always believed that Jesus would return to officially end the world as we know it. Jesus says no one on the earth knows that information.

We will never know the date or time, nor should we believe anyone who claims to know it through “convincing” evidence, special revelation or mathematical formula.

Jesus’ description in Matthew tells us it will happen on an ordinary work day.  Remember how ordinary and beautiful the day of 9/11 was?  You never would have suspected such catastrophe.  It will just be a day of business as usual when all of a sudden. . .Jesus.

But we should live as if he is going to return today, giving us motivation to be prepared when he does.
