I take on board your point with pleasure but I think your arguments in the context of the Flood are not convincing.
It seems to me we both agree in that the basis for any coherent explanation is Jesus’ teaching:
Now, the crucial Jesus’ teachings in this respect are in Matthew 24; 25: 31-46, and Luke 17: 20-37.
As a matter of fact the scholars responsible for the article at the basis of this thread have not even referred these verses. Neither have these verses been discussed in detail in the Interview by Brad Kramer with John Walton @JohnWalton and Tremper Longman @tremperlongman.
It seems beyond doubt that Jesus in Matthew 24; 25: 31-46, and Luke 17: 20-37 is clearly speaking for Christian of all times to convey His crucial teaching about the End Times as a real event to come, making clear, as you yourself claim:
If Jesus were comparing this event to a past event (the Flood) that never took place but was only the result of “purposely exaggeration”, it seems plain that He would actually and “purposely” be proposing to Christians today to interpret His teaching about the End Times and Final Judgement as “purposely exaggeration” as well.
For this reason I think that in the light of Matthew 24; 25: 31-46, and Luke 17: 20-37 “hyperbole” cannot be considered a sound explanation for the Flood, even if one accepts (as I do) that:
You yourself provide an excellent argument in favor of my conclusion:
By teaching “it is better to cut off their hands than use them to commit sin” Jesus uses an expression that I understand today exactly in the same sense as anyone who was listening to Him 2000 years ago understood: “it is better to cut off my hands than…”.
Accordingly when Jesus uses the “Flood” (in Matthew 24; 25: 31-46, and Luke 17: 20-37) he wants us to understand the comparison in the same sense as those listening him understood it, i.e.: as real history.
In summary, Matthew 24; 25: 31-46, and Luke 17: 20-37 clearly suggest that “hyperbole” is not a good explanation for the Flood and therefore, if we want to keep to science, we should take seriously the option Flood=miracle.
In any case I am very thankful to you for your comments: They are allowing us to discuss openly Matthew 24; 25: 31-46, and Luke 17: 20-37.
