Theists, what does faith mean to you?

[Whateverist]

With all respect, but who are you to say what can and cannot be evidence for me?

But "evidence" is worthless if all you can do with it is convince yourself of what you already believe.

I don't disagree, so long as we're talking about what reasonably you can expect to be convincing to another person.  But sometimes the only person you need to convince is yourself, something that comes in handy when clarifying ones own values and beliefs.
