Everything held must be because it has been revealed to one personally.
How can you explain why you are arguing that Christianity is unique to me when it is held by others.
In terms of picking the reasons for belief apart you as a mere uncommitted agnostic have less cause to have attempt a picking apart of personal experience than I have unless you are a stinking lying atheist of the type who pretends to a lack of belief.
The picking apart has been picked apart.
I do not believe that all Christians believe the same thing at all. They just have the same name for the belief set.
In fact I do not believe there are 2 Christians as I think they all believe something different and personal to them. Find 5 people that call themselves Christian, and you have found 5 christianities, each one personal.
I lack believe in your and in fact every body elses god, and that is not a lie, why would you think it would be.
I have not had a personal revelation, and I have seen no evidence up to the job of convincing me there is a god.
To date, no god believer has put forward any evidence that is no logically flawed or full of assertions.
