Yes, I understand that from a certain point, as long as one believes in Jesus Christ they are part of the "church" and saved. (Assuming that Christianity is correct in this matter).
First off, I want to say that these are just my observations, and biased opinions. I'm sure there are many different ways to look at the fact that Christians disagree with each other about parts of the Bible.
However, the point I was making is that it is very curious why there are so many different interpretations of the Bible , each from a denomination claiming that their interpretation is from God and correct.
What I find interesting is when Christians debate other Christians of a slightly different faith about the different characteristics and rules of God. I feel like - 'ARG, Just all sit together and pray and ask God Himself for the answer!' If one were able to communicate
with him in a more accurate manner than we shouldn't see this, no?
In the Old Testament, God would taunt other god's and challenge them to test's. When the false god would not respond, God's people would jeer and say "perhaps he is sleeping!". It is too bad we can't try the same thing against the Biblical God. I guess it "wouldn't be fair" for some reason.
Yes, many agree on the "main" or "important parts" to some degree, but the fact that disagreements exist on what God wants or means (in which case someone is wrong) makes it possible that the core beliefs in Christianity could also be wrong (or untrue).
e.g. That Jesus came to die for our sins, etc.
From an "outsider's" perspective, a bunch of people all claiming to have a relationship with the same God, yet disagreeing on what they think God likes or does just looks like a bunch of people coming up with their own ideas and convincing themselves it is from a higher source. Thus, there is no evidence that a single God is giving anyone answers.
Now if people from all over were communicated something specific from God, without even reading or knowing about the Bible - THAT would be powerful proof that God (and Jesus) were real. Maybe it's just a dream of mine that will never come true.
