From River of Life ministries:
The experience that most influenced Muslims was the lifestyle of Christians, according to a recently released survey that offers a glimpse into why Muslims are opening their hearts to the Gospel and Jesus Christ.
The survey, conducted by Fuller Theological Seminary's School of Intercultural Studies between 1991 to 2007 among 750 Muslims that had decided to follow Christ, was able to track some influences that helped the converts make their decision. The respondents were from 30 countries and 50 ethnic groups - representing every major region of the Muslim world.
The next most important influence was the power of God to answer prayers as well as healing. These revelations of God include supernatural intervention such as Christian prayers healing disabled people when Muslims could not and deliverance from demonic powers.
The third most popular influence listed by respondents was dissatisfaction with the Islam they have followed. The former Muslims said they were unhappy with the Qur'an, which they said emphasized God's punishment more than his love and the use of violence to impose Islamic laws.
It is also noteworthy that more than one in four respondents (27 percent) said dreams and visions were a factor in their decision to commit themselves to follow Christ.
