That's too simplified if you are seeking answers.
Wind cannot be "seen" neither can emotion (excluding manifestations of emotion). A person visible shaking from anger or crying from pain/happiness/pleasure is a manifestation and not the emotion itself.
All of these things are knowable by our senses. No faith is needed.
Suppose you had a group of people that hid their emotions and only uncontrollable emotions were "visible". To the person that controls their emotions they definitely have them but to another only the uncontrolled are visible.
Emotions are a thing we experience. We feel them. No faith is involved. You are saying that faith is something we can have without experiencing anything. I can say that about anything that may or may not be real. I can say that the man in the moon exists There is no evidence that faith in God exists. The proof is that people say what they think God is or what he told them that completely contradicts others and yet they all say that they have faith in the same god and even use the same holy books.
Of course some people are more perceptible than others.
There are a few examples of things that cannot be seen and can only be experienced on an unseen level.
These are
just two examples (Wind & emotions) that came to mind. Faith is quite difficult to "pin" down so to speak and it is critically important to understand (on a practical level) what it is and the distinctions within it.
I have questions regarding it myself. I already know the biblical definition and also that without faith it is impossible to please God (also a scripture). So it is important.
There exists a distinctions between faith & sight in scripture. That is usually my starting place for understanding faith and then engaging the clear differences (if any) between faith & trust.
Does that provide a direction for you? I've considered starting a topic like this several times. I don't want to hijack but it is hard to maintain structure in a thread most times without moderation and moderation isn't employed that way here.
Note: I'm not disagreeing with the way moderation is done on this site, just that there are different approaches depending on collective aims. I don't know the mods, so I am unwilling to critique the system quite yet
