1) Jesus warns that in the last days, perilous times will come with nation rising against nation, famines, earthquakes, and the beginning of sorrows. 2) As it was in the days of Noah, when people were eating, drinking, marrying until the flood came and took them all away, so will be the coming of the Son of Man. 3) Therefore, Christians must stay watchful and be ready, as no one knows the day or hour of the Lord's return.
