Today, a nice, light topic. Destruction and desolation. Nice, eh? First, read this:
Now realize that when Jesus used the word typically translated "hell" in our Bibles, it was really "Gehenna," which means "Valley of Hinnom" or "Valley of Ben Hinnom." Interesting, no? I put this out there for anyone who is still stuck on "Hell means Eternal Conscious Torment." It may be, but the case for it might need to be made on other bases than Jesus' teaching on "hell."
So when you hear a preacher tell you that Jesus spoke more about Hell than Heaven, realize that he's assuming a meaning for "hell" that may not actually be there. Jesus was talking about a garbage dump where dead bodies were thrown, where there were fires constantly burning. It's possible he was implying that Hell would be like that, but with the flames lasting forever (and perhaps the flesh of its victims also lasting forever). Or he may have been implying that those who reject him would be consumed (which still isn't a pretty picture) but not suffer eternally. Or he may be simply indicating the coming destruction of Jerusalem (in A.D. 70), which paralleled the previous sacking of the city by the Babylonians in 586 B.C. (predicted by Jeremiah).
I actually haven't gotten to Thayer's treatment of Gehenna in The Origin and History of the Doctrine of Endless Punishment yet. I'm curious to see how he'll explain it.
