They say that the god would never allow a believer in God to be misled.
Who are "they"?
That is why they trust the word which says "all scripture is inspired of God" as God's words.
That means that nobody can alter the meaning of any of the words in it according to them.
They live by the words trusting in God to use those words to lead them.
If all that is true,
I Assume "they" are theists?
They don't alter the literal meaning of the word, they alter the meaning of the story.
They alter the literal story to be a fable. only some believe the literal word is the absolute truth, not all.
then God allowing Adam to sin has no meaning.
It has no literal meaning.
It does have a meaning in the question of good and bad.
It does have a meaning in the question of free will.
It does not, however, have meaning in the scientific reality (as far as we know to date
)
I am not going to talk about Genesis being a historical account.
I hope not, as it is not.
I would talk about my belief that it has real meaning.
What? the story of genesis?
Why would God allow the first worshipper of God to be misled
why not? free will!
I think the belief is more like:
The law god gave himself of "free will" is much more important than the law of "do not kill".
So for that example, it would be of the same kind of question like: is it worth dying for a "freedom of speech"?
but then actively prevent
any other sincere believer in God to be misled?
