"No one knows the day nor hour."
Jesus taught that no one knows the day nor hour. In the context of this teaching, the disciples understood that the end of the age was like the end of a woman's pregnancy and a new birth, the "regeneration of all things." When a woman is with child we cannot know the day nor hour the child will be born. However, there are signs which tell us that when that time is near. And this is precisely what Jesus teaches.
