Spiritual comfort is filling a gap. After all, the rest of the community, and indeed people from literally hundreds of miles around, came and gave physical and material support in the hours and days after the event to the point where the local voluntary organisations filling the void left by the useless local council simply could not handle the amount of donations.
What these people who had escaped with just the clothes on their back, escaped with their lives, escaped when others in their family had perished really lacked was a Watchtower. What they needed most of all, the hole that had been left by the rest of the relief effort was some patronising words about suffering coming to an end "very soon now"(© WTBTS), God really cared about them and the efforts of the countless kind hearted people around them was just a bit of a sticking plaster on the situation.
Come on people. How dare you be so unfair. Those Witnesses saw the need and filled it.
