Gene Veith has a very interesting and encouraging post about Muslims coming to Christ in Europe and the effect it is having of reviving some near-dead churches in Denmark and Germany and elsewhere. Be sure to read the links he provides within his article for a fuller picture of the situation.
As Veith says,
"The conversions of the Muslims would appear to be God’s work. It
isn’t happening due to church programs or to outreach efforts (valuable
as those may be). It isn’t that Christians are going to Muslims to try
to convert them. Rather, the Muslims are coming to the Christians
asking for the Gospel.
The revival in Denmark–as well as other countries–may just start with the Muslims and then keep spreading."
