Why do Christians think that quoting random bible verses gives credence to them?

[SupaStar]

Why do they understand that in every other aspect of their lives they demand evidence, but in this one area, not only is evidence not required, it is actually rejected?

 

[DrDeanCrosby]

The Holy Spirit repeatedly confirms the validity of the Bible so physical evidence is not required for individual verses.

They've told me gods word is perfect so therefore it can't be wrong, its always right. Circular reasoning.
