Faith is a belief in something even though there is no evidence to prove the belief is legitimate. Many people have faith in god even though they have not seen or met this deity. When you have faith then you are confident in the outcome even though this can not be proven, you are acting on instinct rather than proof.
Worry is spiritual short sight. Its cure is intelligent faith
Faith is different from proof; the latter is human, the former is a Gift from God.
Faith is a euphemism for prejudice and religion is a euphemism for superstition
