Wikipedia seems to have a nice article on how Islam understands Jesus as mentioned in the Quran.
http://en.wikipedia.org/wiki/Isa
I am pretty sure the majority of Christians would never realize that muslims believe in Jesus as a prophet and not as god.
I think i have read somewhere in the Quran that it is our duty to convey the truth regarding Jesus to christians, and show them to the right path.
I don't really think that many Christians will take a deep breath and contemplate for themselves, "hey, i think i was wrong after all.." if we (muslims) keep offensing the christians by attacking their opinions with emotional debates. I am always wondering on how did the early islamic scholars and traders from India, China, and the Middle East was able to convert the majority of Indonesian population who were Hindu and Budha centuries ago. I suppose they used a cultural approach, for there was no war involved in the process. I also assume they demonstrated a high quality of islamic akhlaq (attitude). Boy am i so grateful to be born as a muslim, although i am now living 'down under' where islam is still in a bit of a trouble...
I believe at the time being, mutual respect and more understanding between muslims and christians is much more important than debating who is right or wrong. Because as we speak now, islam is being feared more than ever before, mostly in christian societies, where they believe that islam is the religion of war, of woman repression, and of uncivilised government... This distorted image of islam must be fixed and corrected... especially by act of good attitude and demonstration of great achievements in peace, humanity, economy, and science, instead of debates and unproved words...
