Or, when we determine that we want to reach an objective and we work on it in body and soul. There we are exercising faith, because we show our hope in something that we cannot yet see.
It is said that "faith can move mountains" and it is true. The firm belief that something good is going to happen is the most powerful affirmation that exists. Yourself push to make it happen because your energy, attitude, concentration, conviction, motivation is in it.
Someone may question me: but why, even if I have faith, doesn’t the outcome is exactly as I thought or wanted? The answer is simple: life as our protective mother, will give you what you need in the way that is best for you. Keep in mind that things happen for some reason. So be patient because I'm sure that in a while you will know why things happened that way and not how you wanted or expected. Everything is for your protection and growth.
I’ve heard some people treat faith as if it was a commercial transaction: "if life gives me this, then I promise that"... no, that's not how it works. Faith is unconditional to any circumstance. A person who uses faith with conviction will end up getting what he wants and the best: he will increase his positivism in life and self-confidence.
Skeptics say that "you have to see to believe" ... and I say that those of us who have faith say the other way round: "believe to see"...
