Ofcourse there is GO(O)D within everyone but too often people say or try to believe in a god something outside themselves so their belief cannot be a whole clarity.
Believing in a god means most are looking in the wrong direction so are left always looking, & hoping he will hear them.
When you can SEE YOUR GOOD you will act out your good & inner strength grows & life becomes much easier * less complicated & your faith in yourself & your abilities grow.
Few achieve this by believing in something invisable that often does not hear them.
If everyone knew the holy grail the troubles of the world would be eliminated...but most couldnt even envision this either.
