According to the Bible, men and women, ever since they first disobeyed God, have been sinful in all ages and in all generations.
But there are epochs and times when they are unusually, exceptionally sinful. You will find ages when the Israelites were certainly not living perfect lives, but they were comparatively good. Then there were other outstanding periods when the whole position became desperate.
You see this sort of undulating graph as you follow the history of the human race. Take, for instance, the account which the Bible gives of the destruction of the world in the Flood. That generation was one when mankind sinned with all its might and defied God with unusual arrogance.
