And that would surely happen with wholescale muslim conversion to Christianity, as happened in your example when the Ephesians deserted Diana and their black arts.
Not holding my breath, but I’m doing my part.
From what I have read from missionaries and evangelists, Muslims are the most difficult to witness to of any group, because of the pervasiveness of Islam in every aspect of a Muslim’s life, and because of the real potential of repercussions to a convert. They are as bent-more bent-on converting the world to Islam, as any evangelical or fundamentalist Christian, as testified by their willingness to use violence to force a “conversion”. At least Christians know true conversion to Christianity can’t be compelled, nor are Christians given “permission” by the Bible (as opposed to the Islamic doctrine of “taqiyya”) to lie about their faith for any purpose. We (Christians) are to live and die, if necessary, without renouncing Christ.
