Silverleaf,
If you are asking about religious faith, I believe that faith is belief and trust in God. But one improtant thing was said by joelbear when he said:
As with all things, with faith there is a balance.
I believe him because I've seen Christians that have faith in God have NO balance and their views were so out of touch with reality that I thought they were using God as a crutch. Just for an example, I knew a woman years ago who charged all her credit cards to the max and then when she realized she could not keep up with the payments, she said that the Lord would take care of all of it and would get her out of debt somehow because the Lord never gives people a burden heavier than they can carry. She had no balance whatsoever and my telling her that the Lord didn't put that burden on her, she put it on herself did no good.
Faith has more than one meaning.
peace,
somebody
