The document discusses different interpretations of Matthew 24:40-41, which references some being "taken" and others being "left" when Jesus returns. It argues:
1) The text does not say the righteous will be taken to heaven while unbelievers are left on Earth, as some believe. It simply says some will be taken and some left.
2) Based on the context of Jesus comparing it to Noah's flood, it must refer to His glorious second coming, not a secret pre-tribulation rapture.
3) Looking at Genesis 7:23 about the flood, it suggests those "taken" were destroyed, while Noah and his family were "left" and remained alive
