The world said, "Never again!" but the genocides continue. Russia, Cambodia, Somalia, the Balkans, Iraq, Darfur, and on and on. When will we finally confront the evil in the world!
A companion and I actually stumbled on the remains of a minor concentration work camp one afternoon while we out checking a rural area on our bikes. It was an ongoing effort to restore some of it for a museum / memorial. But, it was not on any map. Part of the land had been turned into a small modern prison, and that was all that was indicated on the map. But, it was only a month or so later that a tourist bus from some charter line in the area was attacked by a french mob... and guess why... well, the charter line had the habit of naming it's buses after geographic names, and this particular bus had the misfortune to carry the same name as this old concentration camp had... which was the geographic name of the area.
I spent a considerable portion of my mission in the metropolitan area that this location was near, and there was still ample residual evidence of WWII around. The remains of the concentration camp. A whole suburb of the city that was bulldozed and turned into a cemetary / memorial park for the war dead and the casualties of the allied fire bombing of the city. Several huge air raid shelters that can not be destroyed (large enough for 4 AAA guns on top of them), the blackened remnant of the old city cathedral (left as a memorial next to the new one built after the war). The hundreds of square acres and acres of munitions bunkers out in a wooded area that got the snot bombed out of them. The bombed out remains of u-boot pens in the harbor. The occasional unearthing of remains of soldiers killed and presumed missing in the waning weeks of the war. For a while, I even served in the namesake ward of the church unit where three of the young AP holders started a resistance movement against the Nazi regime.
We confront the evil in the world every day by living the Gospel as best we can and encouraging others to also repent and follow the Savior.
