Sounds like a plan. I remember once I got a knock on my door with people spreading the word (well, it's happened a number of times, but this time I was in the middle of packing to head to NYC for Passover, and as I was talking with them, my head was next to the mezzuzah on my doorpost). I asked them your question about what happens if someone leads a good life but is not Christian, or all the people who lived before Jesus. The reasoning in their answer (which I've kind of forgotten already) left me baffled.
In fairness, I posted that question on this bb, and got a link to a website, but I have to admit I've only just skimmed the site so far. In any event, if some feels that way about having to be saved, that's fine with me. Just please stop knocking on my door. I can see, in their mind, they're doing something good in trying to save me, but I just find it annoying.
One thing I don't really think highly of is the type who won't even explore other ideas. It's ok with me if someone is really into their own philosophy/religion, but some people don't even want to learn the basics ideas of other religions. To me, it's being small minded, and going through life with blinders on. Or perhaps it's just because it's uncomfortable looking at things that challenge your own ideas. I know a few people like that, and while they're nice enough people, it just seems to me that they're not growing ("I'm comfortable where I am, so why change?").
