In a study of Muslims who converted to Christianity, the authors identify the experiences that led the Muslims to accept Christianity:
1. Respondents ranked the lifestyle of Christians as the most important influence in their decision to follow Christ.
2. The next most important influence was the power of God in answered prayers and healing. Closely related was the finding that some noted deliverance from demonic power as another reason they were attracted to Jesus.
3. The third biggest influence listed by respondents was dissatisfaction with the type of Islam they had experienced.
4. Many Muslims view dreams as links between the seen and unseen worlds, and pre-conversion visions and dreams often lead Muslims to consult a Christian or the Bible.
5. The gospel message, especially its assurance of salvation and forgiveness, is also a significant attraction to Muslims.
6. Next in attraction for Muslims is the spiritual truth in the Bible. Respondents were also attracted by the Bible's teaching about the love of God. Particularly attractive to Muslims is the love expressed through the life and teachings of Jesus.
All of this is consistent with what J.P. Moreland writes about in his latest book The Kingdom Triangle. One side of that triangle is the supernatural power of God, which is largely absent in the western church, but is very active in other parts of the world and influential in many conversions.
Note what is number one: the life and influence of Christians they see and know. We are ambassadors for Christ. The only question is whether we are good ones.
And ultimately it's the uniqueness of God as He has revealed Himself in Scripture and through Jesus. Forgiveness and love are powerful messages to those laboring under the guilt and burden of their sin.
