I'm glad my response helped.  Actually I think I did address the key part of your question regarding observable and measurable results but I'm happy to expound further.  Faith is all about a person's belief system which generally governs how they behave.  Because faith requires a belief in something that's not always easily provable, a person's faith can be correct or incorrect (notice how I didn't type "right or wrong"?) depending on the situation.  For instance, those who believe that instituting additional gun controls is the solution for preventing periodic mass killings have faith that it will achieve their goal.  So far, that faith has turned out to be incorrect but these folks won't accept that which is why they keep pressing for more controls as if that would eventually get them where they want to be.  Others have faith that it won't which is why they push back so hard.  As for God's involvement, as I typed previously, he doesn't do anything...it's all up to us.
