Shift of truth

[Silver]

Did any of you seen anything like this before?
She basically believed something and if anything conflicts with it no matter how convincing and how much evidence backs it up she will reject it as a lie.

It is something called cognitive dissonance. It is where someone would rather believe a lie than the truth because the lie provides comfort whereas the truth removes the comfort.

Also the biggest reason she believed the bible were "small signs" from god. She had small events happening in her life and she somehow connected those events to the christianity. What is that all about?

It is all about self-delusion, thinking if the wind blows in a certain direction at a certain time that it must be a divine sign. Some people will delude themselves into seeing signs in the most mundane events if it supports their self-delusions.
