Where is hell?
The most popular suggestion is that it is at the centre of the earth. (It certainly is hot down there). According to wikipedia: It’s in Norway. Hell is a village in Stjørdal, Norway with a population of 352. It has become a minor tourist attraction because of its name, since people like to take the train there to get photographed in front of the station sign. The station sign reads “Gods-expedition”, an old spelling of the Norwegian word for “cargo handling” – godsekspedisjon would be the current spelling.
Actually hell (Gehenna) is a valley south of Jerusalem where corrupt Jews burned their children as offerings to the god, Molech. It was later “desecrated” by good King Josiah. Jeremiah denounced the evil done in this place. Later rubbish from the city was burned in the valley. Thus the word Gehenna, meaning valley of Hinnom, became a suitable picture of a place of final destruction rather than torment. See 2Kings 23:10; Jeremiah 7:31; 19:2.

Beryl Ching, in her article on the resurrection in Acts, mentions a time when Peter and the other Apostles were called before the Sanhedrin to give account for their witness to the resurrection. The upshot of it all was that they were flogged and then let go under orders never to speak in that name (the name of Jesus again).
