Trust is math. Faith is a choice. One is determined; the other is an action. Trust is not a choice. Likewise, faith is not math.
Proof: Choose to trust a random person on the street to pilot your family on a 737 airliner. You can’t. Because trust is not a choice. Choosing to allow the almost-certainly-not-a-pilot person to fly your family would be an act of faith as you would not have any evidence that the person you chose was actually a pilot capable of flying such a complicated aircraft.
Exercise: Imagine your favorite food. Choose to not like it. And then try to trust yourself that you no longer like your favorite food. You have five minutes to accomplish this task.
I doubt anyone could train their own bodies to reject the taste of their current favorite food in only five minutes, but I suppose that’s possible. The point here is that one would have to change not only what one thinks but also one would have to change the body’s physical response to the flavor and substance of the food. In the meantime, it would be impossible to decide and truly believe that one’s own favorite food is no longer enjoyed.
Our context and culture also determine what we like or don’t like. These are determinants of trust, and once set, if queried, the answer cannot be changed after the fact. This is why the loss of trust is so destructive, because once one’s trust is destroyed in something, it’s impossible for the person to choose otherwise. They literally do not have a choice.
