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.
Your faith will perform miracles especially when you get your hands and feet involved
Every life is a profession of faith and exercises an inevitable and silent influence
How many things we held yesterday as articles of faith which today we tell as fables
There lives more faith in honest doubt, believe me, than in half the creeds
