Right before His death, Jesus told His disciples key details about His return saying:
“For as were the days of Noah, so will be the coming of the Son of Man. For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, and they were unaware until the flood came and swept them all away, so will be the coming of the Son of Man.” Matthew 24:37-39
This Scripture is important for several reasons.
First, not only does Jesus know the catastrophic historical events recorded in Genesis 6 and 7, but He also knows His audience is familiar with them. Their prior understanding of the flood’s unexpected, total destruction is the basis for His comparison.
Second, Jesus describes the normal actions of the people living in Noah’s day as “unaware” that a flood was coming. This is how we hear people describe natural disasters; they are consistently surprised by them. It is an interesting note of historical authenticity that plays into His comparison.
Third, Jesus says the flood swept them all away. The fact that Jesus is linking an event where “all flesh died that moved on the earth, birds, livestock, beasts, all swarming creatures that swarm on the earth, and all mankind” to His eventual return, means something about that return. It’s going to be big, and it’s going to affect everyone.
According to Jesus, Noah, the ark, and a global flood that killed all the birds, beasts, and people on the earth, were as historically real as His second coming. They are a historical preview of coming attractions that everyone would be wise to remember regarding their timing and scope.
This is one of the many reasons the idea that Noah’s flood was local somewhere in the Middle East is a misguided interpretation. It does not fit the language of Genesis, which is well-known to both Jesus and His disciples and is central to His comparison. Were the flood recorded in Genesis just local, it would make Jesus’ comparison be that ‘my return is going to be local, and it’s going to affect a few living creatures.’ But that’s not what either Jesus or Genesis says.
The fact that Jesus was well acquainted with the actual words of Genesis and knew them to be real history is why it is such a powerful statement. If Noah was not real, or if everyone in the world was not killed, or if the flood was not global, then Jesus’ comments make no sense. Jesus would say to a modern audience debating Noah and the extent of the flood, “Have you not read what I said about them?”
