They were really missionaries, not aid workers, and thus technically illegal by Afghanistan law, although they were allowed in anyway. Taliban-types are likely to view them, as to treat them, as sub-human. I admire these young people, but now is not the time to try to convert Afghanistan to Christianity.
If they are killed, they will be martyrs for Christ. Does God love the foolish? Yes, indeed, when they are fools for Him.
