What does Luke 17:34 mean?
Because of frequent misuse, the most frequent question regarding this verse has nothing to do with the actual context. Jesus has been warning His followers to be ready to abandon their earthly lives when He returns. Here He explains that some of those with whom they have close relationships will turn out to be nonbelievers. Yet the typical question is whether this verse is Jesus affirming homosexual relationships.The answer is no, it clearly does not.
In Jesus' era, extended families often shared a single home. If the house was small and the family was big, the men slept in a large room on the lower level, and the women and young children slept on the floor above. As many people with large families can attest, sometimes family members must share beds. Absolutely nothing about the context, culture, or language used here implies sexuality.
Modern misinterpretations—often deliberate—distract from the actual point. When Jesus returns to judge the nations at the end of the seven-year tribulation, family members will be separated. Jesus brings division in households. Father and son could be so close that they sleep in the same bed, and yet one will follow Jesus and the other won't (Luke 12:53). For us, that's both a conviction and a consolation. We should be sharing the gospel with those who are closest to us. But, in the end, we cannot make anyone choose Jesus. Nor can we know, infallibly, who is or is not saved (1 Samuel 16:7).
"Taken" would seem to refer to the rapture. However, previous warnings are about "the days of the Son of Man:" the judgment at the end of the tribulation (Luke 17:22). The Greek root has to do with association, such as taking something or someone to oneself or receiving something. In context, one person is going to judgment and the other to dwell with Jesus. Since it's the end of the tribulation and the millennial kingdom is imminent, perhaps one is "taken" to judgment and the other is left to experience Jesus' reign on earth. On the other hand, one may be "taken" to salvation while the other is left to experience judgment on earth. The greater point is that they will experience different fates. And they will be separated for eternity.
