Prove all things....1 Thessalonians 5:21
The thing about faith...it can't be proven..
There are other concepts of faith. The word is used to refer to more than just one thing.
Paul Tillich said faith is just a concern with ultimate reality. I’m not sure any kind of concern can be proven, or need be; it’s about as subjective as it gets. Seems to me wanting to know ultimate reality and proving all things would be mutually supportive processes.
Interesting, I've never heard anything like that. In my corner of the world..gullible means believing
things without proof, naive means believing things without proof, and faith means believing things without proof, that was my experience.
