Since I'm still gobsmacked with the idea that 6 million Muslims in the Middle East convert to Christianity each year, I decided to do a little research to find out why.
Intentional Disciplines has done a splendid post on why Muslims convert based on a study that used an extensive questionnaire with respondents from 30 countries and 50 ethnic groups that gives us a more informed picture then mere anecdotes as to what's going on.
There's a lot more discussion for each of the following five most frequently mentioned reasons and, if you are as interested as I am, you'll want to read the whole thing.
1) The lifestyle of Christians. Former Muslims cited the love that Christians exhibited in their relationships with non-Christians and their treatment of women as equals.
2) The power of God in answered prayers and healing. Experiences of God's supernatural work—especially important to folk Muslims who have a characteristic concern for power and blessings—increased after their conversions, according to the survey. Often dreams about Jesus were reported.
3) Dissatisfaction with the type of Islam they had experienced. Many expressed dissatisfaction with the Qur'an, emphasizing God's punishment over his love. Others cited Islamic militancy and the failure of Islamic law to transform society.
4) The spiritual truth in the Bible. Muslims are generally taught that the Torah, Psalms, and the Gospels are from God, but that they became corrupted. These Christian converts said, however, that the truth of God found in Scripture became compelling for them and key to their understanding of God's character.
5) Biblical teachings about the love of God. In the Qur'an, God's love is conditional, but God's love for all people was especially eye-opening for Muslims. These converts were moved by the love expressed through the life and teachings of Jesus. The next step for many Muslims was to become part of a fellowship of loving Christians.
