And let's not forget, what religion is worth anything that doesn't claim a corner on the 'truth'?? If I have two choices A or B in order to get to C (heaven). Well if B says it is the only way to C and A says well you can go to C straight from A or you can also get to C from B. Well I know which choice I'm gonna make! Why risk going to A since it is in agreement that B is a valid choice.
I've only got one life to live, I want to choose the way that leads eternal life.... who doesn't? And believe it or not, I want that for you (and everyone else too... in fact that's why we share our religious beliefs with others... not out of dogma, but out of love and wishing the best for others).
Anyhow, any religion that claims to be just one of many is a lie. It isn't worth the risk (as I mentioned above).
And if we think that since we have a bunch of mutually exclusive choices [i.e. A, B, and others all claim to get me to pont C (heaven)], we'll if I throw up my hands and say that none of them must be true. That too is a falsehood. It just means that I cannot prove that any one of them is true... and I don't want to pick. Mutual exclusion does not indicate falsehood my friend.
I've heard it said before... whatever you serve, now that shows who your god is! So, who's it gonna be?
Jesus proclaimed he was the way and the truth and the life. So he was either a liar (knew it was wrong), a lunatic (thought he was divine and wasn't) or he was/is Lord (son of the almighty). As someone said before, Jesus didn't leave us the option that he was just another good guy (as Islam would like you to believe... as I think they state he was another prophet).
