Wow MrD
Do your friends talk about their Christianity to muslims? That is amazing. I would think they are in more danger in Paris among the muslims than they were in Egypt or Morroco.
Well, one friend of mine (and his wife) talks about his Christianity with Muslims. Anytime someone encourages Muslims to convert to something else, that person is in danger no matter where he is, but I think his time in Egypt was probably the most dangerous. He was there during the overthrow of Morsi, so there was open violence.
Despite the dangers, he views this as the primary calling on his life, and he enjoys doing it and has good things to say about the Muslims. To him, they're just lost people who need to hear the gospel, and sadly, they're not likely to hear it from the Parisians who are overwhelmingly secular and don't speak Arabic. Aaron and his wife do.
In addition to money a prayer or two could help.
Undoubtedly.
