As a matter of fact, I am a full time missionary. My family links to a particular Muslim country, my travels in the Muslim world and the years I have lived among Muslims in Muslim countries, have provided me a good and solid exposure to Muslims converting to the Christian faith.
FALSE CONVERSIONS
Certainly there are some false conversions, in which the main intention is an attempt to get visa for any Western-like nation, or get money.
Funny enough, some or a majority of Muslims consider the West to be Christian , thus if you are a Christian living in a Muslim country you should benefit from the West; this only reveals the typical ignorance among the average Muslim concerning Christianity.
Some or a lot of Muslims convert falsely to Christianity in order to spy on other converts; this is one of the particular dangers I have personally witnessed.
When the converts are exposed to a spy, they are ussually exposed to great danger, that of being informed, arrested or lynched.
I assume some convert due to severe powerty and need, I just havent met them yet.
The converts I have met, are ussually not the devestated ones, but fairly educated and informed about their own religion.
They convert for several reasons:
To escape eternal hell fire
To find peace with God
THEY READ THE BIBLE
A range of them have read the Koran and the Bible, in which a comparison has a stong effect upon a open mind.
Funny enough I meat a lot of Muslims who are terrifid of reading or having read bits of the Bible.
Some keep up their courage, and answer, if asked whether they have read the Bible: that they were unable to continue, due to so many mistakes.
REVELATIONS AND MIRACLES
A high number of ex-Muslims I have become aquainted with, became Christians after a revelation or an act of miracle.
In 1996, on a trip to Pakistan, two Muslim families from the same town, were victimised after their conversion to Christianity.
The first family had seen a revelation of Jesus while under way to Hajj, they turned back, and embraced the Christian faith.
As a punishment from the community, the family business was burned and destroyed, as a first step of forcing them to recant.
The family managed however to escape, and I have not heard of them since.
The second family, also Muslims, converted after the wife in the house was healed from a fatal sickness as a Christian neighboring friend had prayed for her.
When the news came out, both husband and wife were eliminated (killed) and the children forcible adopted by a uncle.
I know a former Jihadist, a officer whose duty was to commit genocide against non-Muslims; he and his battalion killed a lot of people. Until one night when they were about to execute a Christian family, when fire from above torched the area around the family and he and his fellow soldiers ran away. He told me that after that experience he left Islam and became for a time being a atheist. Later after a encounter in which he had a revelation of Jesus he converted to Christianity.
He has gone through terrible agony because of his decision, e.g. his family poisoned his foot, he survived, and later his son was killed as a punishment.
THE ETHICAL FACTOR
Some ex-Muslims I have met, decided to consider a alternative to Islam, due to the ethical side of their religion.
In Pakistan for example, Muslims deplore the fact that Muhammad married a nine year old.
Recently a Christian was imprisoned for merely referring to the particular issue.
One of my close friends a former Muslim student and preacher, reconsidered Islam, when realising that his prophet in the age above 50 married a nine year old.
Later he embraced Chrisitianity, today he is preacher.
I used to attend aN Iranian church and have close ties with a Afghan church (probably the only one in the world those days) in a particular Asian country.
We had to deal with the problem of spies, e.g. they would check out our carbage to find any possible letters, they received copies of all the pictures we developed, they kept eye to our houses, our activites, everyting.
We even had a girl being able to escape an attempt of kidnapping by the Iranian embassy car.
Most of these people had a story of dramatic conversion, persecution and escape.
A ex-Muslim (now Christian) missionary I met, at least, informed me that through 20 years of preaching he had lead 200 Muslims to the Christian faith, most of them who were now involved with similar activities.
The story is the same all over, even here in UK were I am based at the moment.
There is a flow from Islam into Christianity at the moment, and if all these conversions are real, well as the Bible teaches, time and life will show.
