Will the people who were destroyed at Sodom and Gomorrah be resurrected? It's a tough question for Jehovah's Witnesses. They were destroyed, but there was no warning work like the Jehovah's Witnesses think they are doing today. It seems inconceivable that God would destroy someone and then resurrect them for another chance. On the other hand, if God was able to just read their hearts and destroy them without giving them a warning, then the preaching work of Jehovah's Witnesses seems pointless. This kind of confusion leads to flip flops, as this video demonstrates. Jehovah's Witnesses believe the light grows brighter. In this case the light appears to be flickering.
