Jesus described the last days very graphically. They would, He said, remind us of the Days of Noah but they would be far worse. Even believers will be caught up in the worldly spirit of the age and many will find their love and commitment to the Lord waning. But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone.
For the coming of the Son of Man will be just like the days of Noah. For as in those days which were before the flood they were eating and drinking, they were marrying and giving in marriage, until the day that Noah entered the ark, and they did not understand until the flood came and took them all away; so shall the coming of the Son of Man be. Then there shall be two men in the field; one will be taken, and one will be left. Two women will be grinding at the mill; one will be taken, and one will be left.
