Matthew 24:36-40, 44

“Concerning that day and exact hour, no one knows when it will arrive, not even the angels of heaven—only the Father knows. For it will be like it was in the days of Noah when the Son of Man appears. Before the flood, people lived their lives eating, drinking, marrying, and having children. They didn’t realize the end was near until Noah entered the ark, and then suddenly, the flood came and took them all away in judgment. It will happen the same way when the Son of Man appears. At that time, two men will be working on the farm; one will be taken away in judgment, the other left.

So always be ready, alert, and prepared, because at an hour when you’re not expecting him, the Son of Man will come.”
