36 “But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone. 37 For the coming of the Son of Man will be just like the days of Noah. Matthew 24:36-42 (NASB) (Read verses 38-42 on the site)
Jesus’ own words from the Gospels tell us that the time of His second coming will be as it was in the day of Noah. What was that like? People were eating and drinking, marrying and giving in marriage right up to the time Noah entered the ark. They were unaware of their coming judgment until the flood came and swept them away. People were going about their normal business of making a living, doing the best they can, just like now. Jesus also tells us that no one knows when He is coming back, therefore we are to stay awake or be alert.
