Paradox

Many divisions of Christianity agree that all it takes to be saved and go to Heaven after death is to have faith in God and accept the Lord into your heart, I think it's called "salvation by grace and faith" or something along those lines. If this truly is the scenario, then why do so many Christians go for the "fire and brimstone" approach? If you're already set to go to Heaven by accepting God, then what is the point of preaching that people are all going to hell? If you prescribe to this particular approach of salvation through grace, it's not possible to gain "brownie points" with God; you're already loved indiscriminately no matter what you do, as long as you have faith.

That's why I don't understand people who seem to try and do the complete "goodie two shoes" approach, for lack of a more appropriate term. You're already loved, so what's the deal? I'm not at all saying that you should take that "salvation through grace/faith" message and say "Okay, whatever, I believe and I'm saved, so I'm gonna be a shitty person and do whatever I want, no matter how immoral" because, even though I suppose you could technically do whatever you want more or less and still be saved, the values extolled by the bible are just good to follow to be a kind, good person, even if you're irreligious. However, there's no reason to go around with a "holier than thou" attitude and preach out at people, I don't think, which brings me to my next point that confuses me:

I think it's really funny that many "devout" Christians seemingly tend to pass judgement on others, even other Christians. I am a Christian. I accept Jesus and God. However, I don't follow the same views on the matter as every other Christian, but why does that make me a worse Christian? Even if I were to totally reject the idea of Christianity, I don't see why so many Christians take that as a right to judge and ostracize those who have that viewpoint. It's just a different world view, and by judging those people, the very values Christians try and uphold are blatently disregarded.

Confusing stuff.
