Faith is a word with many meanings and connotations. It means different things to different people.
I like to use the word as it applies to people and my relationship to others. I say faith is a belief in people. Faith is trusting in people. I have faith in my fellow human beings. I believe that given the opportunity to do a good and honorable thing, all people will do it. Even those that society has beaten into the ground will rise up and help someone else when needed.
Yes, for me faith is very simple.
Faith is trust in my fellow human beings.
