In your opinion what causes christians to believe in Jesus

[Sheldon]

Evidence is simply the available body of facts or information, indicating whether a belief or proposition is true or valid. Whether that evidence is sufficient on any given proposition is another matter, but the more that evidence is interpreted subjectively, the less reliable it becomes, the more objective it is, the more reliable it becomes.

I don't think it's true to say that evidence is the available body of facts or information. 

evidence
noun

1. the available body of facts or information indicating whether a belief or proposition is true or valid.

Whilst you're entitled to an opinion, I am going to have to go with common usage in the dictionary. 

They become evidence when a human being interprets them in support of a conclusion. 

No, that's when they become SUFFICIENT evidence, FOR THAT HUMAN BEING. Of course I have already stated that the more subjective the interpretation, the less reliable that evidence is. Whereas John has claimed evidence doesn't exist. only interpretation, which seems to be what you're saying. It's an attempt by him to imply his entirely subjective religious belief, have some sort of parity with objective facts.
