Faith is a force you command. You have the power to put faith in something or someone. When you do we say that you believe in an idea or a person.
Confidence is the feeling you create for your self by investing your faith in something or someone. Oddly you can create this feeling of confidence even if the idea is a lie or the person you believe in is a fraud.
A spiritual warrior is aware of how his or her belief in something can create a false sense of safety.
