This article by Dr. Patrick Sookhdeo provides great insight into the challenges and tensions concerning Christian ministry to Muslims.

It deals with such things as:

• The impact of 9/11, and how various governments dealt with the issue of violent Islamic extremists
• Various efforts concerning Christian-Muslim dialog and the InterFaith movement
