Converting others is the main function of the modern believer.
The above quote only applies to christianity. Judaism does not attempt to convert, in fact it discourages it. Judaism does not believe that everyone else is going to hell.
The NT has a million internal (by which I mean the gospels dont even agree) as well as external contradictions (by which I mean, the books can not be reconciled with what historians believe). Do a google search on the web. Im not going to name them all. (an obvious one is the timeline around jesus birth (presumably an important event) is impossible to reconcile with history).
The debate over whether jesus existed continues. Obviously, a large part of the world and the U.S. is Christian so they believe he existed and that he was the son of g-d or god incarnate. Among atheists and non-christians, opinion is split (as to whether he existed-obviously atheists and non-christians do not believe he is g-d)
Many non-christians doubt jesus existed, or if they concede he existed than they doubt whether he was crucified. (Again, do a google search-you can see the million articles pro and against)
The koran asserts that jesus was not crucified.
The gemara (ancient jewish text) describes about 5 people with stories similar to what the new testament describes. The Gemara also describes the Christian movement as begining about 150 years B.C. In that 150 years, there were about 5 ppl (one actualy named Jesus) who preached christian teachings-3 were crucified and 2 were stoned (the guy named jesus actually was stoned and not crucified).
Many Jewish scholars believe that NT jesus was actually a combination of those 5 people with a large plurality based on the guy actually named jesus. To support their theory (and thats all it is, unless you were alive 2000 years ago, noone can know), they point to the stories in the gemara about the 5 people, the fact that early christian writings fail to mention jesus as a flesh and blood person until about 100 years after jesus' supposed crucifixtion.
They also point to the fact that the book Jewish antiquities which describes all of the important ppl in Jewish history that was written around the turn of the first millennium makes no mention of jesus as an important person (which supports the notion that there were several and it was the christian movement that was important).
(There is a section that talks about Jesus and his ressurection but the church admits that it is a fraud. some church scholars insist that the whole section is not a fraud just certain parts about the ressurection were added-well never know)
The saying goes that the victor writes history. Christianity has been victorious now for nearly 2,000 years and even the church admits that certain writings are not legit.
Bottom line is that religion (all religion) is belief, if you choose to believe that is your choice. Just because there are arguments to knock holes in christianity (as there are for all religions) does not mean its invalid. Often ppl believe things they cannot prove.
Many things I believe in I can not prove . Personally, I do not find christianity or the existence of Jesus as g-d and savior convincing but that is my belief and everyone is free to believe what they want. What bugs me is when christian missionaries suggest (and I have seen it at old age homes) that you have to be out of your mind not to believe in christianity.
Ok, Ive got to get back to work.
