Islam is not such a megalithic thing that many muslims would have people believe. There are many who are called muslim that simply live in areas controlled by muslims. There are many muslims who practice a syncratic mix of Islam and animism, there are many muslims for whom Islam is simply a culture and not a religion of the heart. There are people who are reaching out, AND being successful amongst muslim peoples.
I had a conversation once with a muslim apologist who was complaining to me how unfair Christian missionary practices were because so many muslims were having visions from God of Jesus and there were so many that were being healed by Jesus that it wasn't fair. I hope he one day realizes what he was saying. Instead of realizing he was witnessing the power of God he seemed to understand there is power in Christianity, but he didn't consider why Jesus would be performing healings when Christian would pray.
