Saved by the Skin of their Teeth

"It was the same as happened in the days of Lot: they were eating, they were drinking, they were buying, they were selling, they were planting, they were building; but on the day that Lot went out from Sodom it rained fire and brimstone from heaven and destroyed them all. "It will be just the same on the day that the Son of Man is revealed. (Luke 17:28-30)

I wonder if there may be two groups of Christians in that day. One group will be like Abraham living in harmony and close communion with God and keeping a distance between their lives and the corruption concentrated in the cities. The other group will be living very close on the edge of sin, living in the midst of sinful environments and having their witness for God compromised by their familiarity with it. Their families will be contaminated and they will only be saved by the skin of their teeth, dragged out by angels and suffering losses of members of their families in the process. Their works will be tested by fire and will be burned up but they will be saved – barely. (see 1 Cor. 3:12-15)
