Triple A
Cain brought some of the fruits where Abel brought fat portions and the firstborn. Abel gave of his best, where Cain did what he had to. It was not what was given, but how it was given.
In verse 7 God could see that Cain?s heart was intent on sin and it was close by.
To begin with, the whole story is ridiculous.
Animals were not supposed to have been eaten, even by other animals, before the flood. They all ate fruit and vegetables. (the babble doesn't say anything about them being forbidden from eating from the life and wisdom trees).
If nobody, including animals, were not allowed to eat flesh, How did Abel knew which parts did big J like, or why does he have this thing about killing the first born? Was big J beaten up by Moloch and develop a hatred for older brothers?
The babble constantly mentions that the smell of burning flesh brings him to a state of rest. Maybe that is what he uses instead of marihuana or hash to mellow down.
