Assuming Christianity is the One True Religion

AJ, a roommate and friend, Asks: When Christians say that their religion is the only true religion, do you feel that it's wrong for them to say so?

I am unable to prove my Christianity, but I assume it's true because it makes more sense than the alternatives to me. By principle, I wish not to place my assumptions on others as truths. Therefore it's not right for me to push Christianity on others as the most superior choice, among other things, with my current level of knowledge.

If someone besides myself has transferable proof that Christianity is the only true religion, I would hope that person is honest to what he or she knows and tells others. On the other hand if that same person doesn't have transferable proof for his or her statement that Christianity is the one true religion, I wouldn't understand why the statement would be presented as such, as it could possibly be a lie. By the Bible's definition of Christianity, it's wrong for Christians to lie. Therefore such a statement also risks hypocrisy . At the same time, I wouldn't be able to impose my assumption on that person that he or she doesn't know what he or she is talking about, because I don't know what the answer is either. If I were that person, I know that it would be wrong for me, though, to say that Christianity is (implying absolutely) the only true religion without first being able to prove it. I think it would be much more accurate for me to say that I think Christianity is the only true religion.
