Now back to these verses:
"Two women will be grinding grain together; one will be taken and the other left.” “Where, Lord?” they asked. He replied, “Where there is a dead body, there the vultures will gather"
You say that the Apostles were asking "where" this would happen--where two women would be grinding grain together.
But if that is the question then the answer given by the Lord Jesus makes no sense whatsoever. If you are right then the Lord Jesus would be telling them that the two women were grinding grain together "where there is dead body," the same place where vultures gather. That is ridiculous since the time prior to this event all things were normal as they were before the flood:
"And as it was in the days of Noe, so shall it be also in the days of the Son of man. They did eat, they drank, they married wives, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all"
On the other hand, the Lord Jesus' answer would make perfect sense to those who asked if they were asking Him "where" it is that those go who are taken. They would understand that those taken are taken to where the vultures gather, a place where there are dead bodies. They would understand that those who will be taken will be the ones who are the unsaved.
