Despite what you may have been told, faith does not constitute a belief in a Deity.
Faith is believing in your own hunches, your instinct, your true gut. Because no abstract disconnected notion of Deity "out there" tells you more about truth and the way things are than that small voice inside of you that cries out to you, nags to you, whispers to you when you make any given choice -- good bad, or indifferent.
Trust and listen to it. It is never wrong. What is that voice anyway?
However, be careful that you don't get "radio interference" from all other things stuck inside your head -- hangups, biases, needs and desires. The voice of true faith is clean and impartial.
And it is always right.
