Back to front?

Sometimes people read things, particularly bible things, and understand them back to front.

Matt 24 v36-41 "No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. As it was in the days of Noah, so it will be at the coming of the Son of Man. For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. Two men will be in the field; one will be taken and the other left. Two women will be grinding with a hand mill; one will be taken and the other left.

The various revelation societies have assumed it's the Christians that are taken, and I understand why. But the context of this passage suggests it is the Christians who are left behind. I'm not building an alternative theology on this, but it's worth noting that the current 'classic' interpretation may not always be correct.
