From 1991 to 2007, Fuller Theological Seminary's School of Intercultural Studies conducted a survey among 750 Muslims who had converted to Christianity. Those surveyed represented 50 ethnic groups from 30 different countries. Here were the nine most-cited reasons for conversion to the Christian faith:

1. Christians practiced what they preached.

2. Christians appeared to have loving marriages in which women were treated as equals.

3. Christian-to-Christian violence was less prominent than Muslim-to-Muslim violence.

4. The prayers of Christians had healed the disabled and delivered others from demonic powers.

5. The Koran had produced profound disillusionment because it accentuates "God's punishment more than his love, and the use of violence to impose Islamic laws."

6. God had used visions and dreams to influence the converts' decision.

7. Muslims can never be certain of their forgiveness and salvation as Christians can.

8. As they read the Bible, the converts had been convicted of its truth.

9. The converts were attracted to the idea of God's unconditional love.
