I know of many such occurrences. Are you suggesting that many more miracles are happening today? One of the reasons I want a count is to determine if this is true on a per-capita basis.
That probably depends of what part of the world you are talking about. In Africa millions of Muslims are coming to Christ every year, with over 40% of them being drawn through a dream, vision, or being audibly spoken to by Jesus Christ. A large percentage of pastors are former Imams. I believe the Lord is in the process of calling in the last of His elect worldwide.
As compared to Europe, for example, where society secularized, and the "church" is dying, with Satan taking full advantage of the vacuum:
"Muslims in Europe are increasingly converting empty Christian churches into mosques.
The proliferation of mosques housed in former churches reflects the rise of Islam as the fastest growing religion
in post-Christian Europe."
"
As Islam replaces Christianity as the dominant religion in Europe, more and more churches are set to become mosques, which increasingly serve not only as religious institutions but also function as the foundational political building blocks for the establishment of separate, parallel Muslim communities in Europe that are based on Islamic Sharia law."
"In addition to Roman Catholic churches, some Protestant churches have also been converted into mosques in Germany, where the Muslim population has jumped from around 50,000 in the early 1980s to more than 4 million today.
In Germany as a whole, more than 400 Roman Catholic churches and more than 100 Protestant churches have been closed since 2000, according to one estimate. Another 700 Roman Catholic churches are slated to be closed over the next several years."
"Overall, at least 10,000 churches have been closed in Britain since 1960, including 8,000 Methodist churches and 1,700 Anglican churches. Another 4,000 churches are set to be closed by 2020, according to Christian Research, an organization that tracks religious trends in Britain.
By contrast, there are now more than 1,700 official mosques in Britain, many converted from former churches."
