Derry recently asked me what my biggest burden was on his blog. That was a hard question because I actually have 6,739+ burdens. The reason I am passionate about raising up Unusual Soldiers is only because I know that I can not take on my burden alone.
This list pretty much sums it up. This page(click all least/unreached people) may take a while to load, but let that only be a reminder of the size of the burden I carry.
