I was showing that there was specific sins associated with the destruction of Sodom and Gomorrah, as well as the time of Noah.
I don't think you showed it. You posted some verses with an explanation, but I gave a counter explanation which I think was more consistent with the over all context. For example, you linked homosexuality to Noah's day by listing a verse which describes the rebellion of angels and the rebellion of Sodom as meaning the angels were guilty of the same sin as Sodom (though the verse doesn't say that) and then listing a verse about how there were angels found in Noah's day, thus presuming the angels were guilty of homosexuality and that's why Jesus brought Noah's day into the picture along with Sodom.
It's a rather convoluted connection which feels more forced than consistent with what Jesus actually said (or what the other verses actually say), especially since Jesus didn't mention anything about homosexuality when listing the sins of Noah and Sodom's day.
Anyway, Jesus says it will be like this in the end, when people are concerned about all these various ordinary things. I think the buying and selling part is particularly intersting because the Mark of the Beast, which is very much an end-time issue, is also described as the means through which buying and selling will be controlled (Rev 13:16-17).
For a world dependent on buying/selling, that's an important part of the prophecy, yet one which is almost universally disregarded by most Christians. It's very much like how Jesus described the end times; people will be too busy with buying and selling (and all the various ordinary activies of life) to care about what God wants.
For context, compare these two teachings;
LK 17:26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
LK 17:27 They did
eat, they
drank, they
married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
LK 17:28 Likewise also as it was in the days of Lot; they did
eat, they
drank, they
bought, they
sold, they
planted, they
builded;
-----------------
LK 14:17 And sent his servant at supper time to say to them that were bidden, Come; for all things are now ready.
LK 14:18 And they all with one consent
began to make excuse. The first said unto him, I have
bought a
piece of ground, and I must needs go and see it: I pray thee
have me excused.
LK 14:19 And another said, I have
bought five
yoke of oxen, and I go to prove them: I pray thee
have me excused.
LK 14:20 And another said, I have
married a wife, and therefore
I cannot come.
The idea I see being communicated here is one of people who are just too busy doing their own thing to be concerned about what God wants. This includes sexual immorality, but also includes all the ordinary, normal stuff which most of us would just naturally assume God would have no problem with. It's not that these ordinary things are wrong in themselves, but that we may be involved in them without concern for what God wants on the assumption that God could not possibly have a problem with us in these various areas. I think this kind of thing has always been around to some, but these days it just seems to be everywhere.
