Actually, we are instructed to watch for the signs, even though we may not know the hour ... as it was int he days of Noah, etc. Jesus spent no small amount of time instructing on this very topic.
That's what you think, right?
AS IN THE DAYS OF NOAH
“But as the days of Noe were, so shall also the coming of the Son of man be” (Matthew 24:37).
Let us now go to the book of Genesis and learn more about the days of Noah.
GOD FORETOLD THE NUMBER OF YEARS UNTIL THE COMING JUDGMENT
God revealed to Noah that man’s days would be another 120 years until the judgment would come:
“And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years” (Genesis 6:3).
