Saying you believe in God and actually believing in God are not the same. Saying you have faith and actually having faith are not the same. Believing in God is a 24/7 demonstration of selflessness and love. There is no room for ego in believing in God. Having faith, is tiring. It is so much work. "Faith without works is dead." Faith is holding one's self to the highest standard of action, solely for the benefit of God. Not for the benefit of self. Self may reap rewards if faith is acted upon properly, but that is not the goal of having faith. The goal is to always be in service of the Divine regardless of the outcome.
