I have some questions for the religious evangelists

I have some questions for the religious evangelists. If you are willing to politely state your view, please leave comment as answer to my questions.

I check out wikipedia and found that about 28% people believe in Christianity and 22% in Islam.

As a religious evanglelist, you, I suppose, will argue for your faith. So my first question is why you are convinced that 3 quarters of the people in the world is wrong and you are right that your god is the true god?

A follow up question is for the Christian and Islam evangelists. Why the god of the other faith (e.g. if you are Christian, the other god is that from Islam) is NOT the true god?

Finally, please convince me that I should believe in your god. If you are attempting this part, bear in mind that I hate tactics like sending me to hell in the after life stuff. I won't buy. Tell me good things. For example, any good deed that normal people without religion will never do, i.e. good deeds that only religious people will do. Hint: you will need quite a lot good deed facts to counter-balance the bad thing religions have done to human civilization and human moral advancement. Mother Teresa of Calcutta is NOT a sufficient example as what she has done, while great and good in nature, can also be done by any good people without regilious belief. In fact, she later expressed grave doubts about God's existence and pain over her lack of faith. See this extract

Where is my faith? Even deep down … there is nothing but emptiness and darkness … If there be God—please forgive me. When I try to raise my thoughts to Heaven, there is such convicting emptiness that those very thoughts return like sharp knives and hurt my very soul … How painful is this unknown pain—I have no Faith. Repulsed, empty, no faith, no love, no zeal, … What do I labor for? If there be no God, there can be no soul. If there be no soul then, Jesus, You also are not true.
