You must believe the Bible right now - Part 1

Here's the argument:

"If you start questioning certain parts of the Bible, where do you stop? You'll have to question all of it, and where do you draw the line between bits you ignore and bits you believe?"

Here's my opinion of that argument:

Not an argument at all: doublethink.

Here's another argument:

"If you start questioning certain parts of what the Prime Minister says, where do you stop? You'll have to question all of it, and where do you draw the line between bits you ignore and bits you believe?"

This is clearly rubbish.

You can't dictate what you believe by looking at the consequences of that opinion.

You have to decide in all conscience what you think, and then live with the consequences.

Here's another argument:

"I can't believe the world is round until after next summer, because I'm going to Australia and I don't want to fall off."

What you believe doesn't change the fact that the world is round. Similarly, what you believe doesn't change the Bible.

I'm not saying that the Bible contains untrue things. What I am saying is that if you think it might, the argument above is not a good way of persuading you otherwise.

Is it possible to be a Christian and think that some parts of the Bible are wrong?
