“ Faith consists in believing when it is beyond the power of reason to believe. ” ― Voltaire

Have you ever required proof that God or goodness or dreams exist? Faith is based on non-provable phenomena.  That's what marks it as faith.  It is a state of mind, a serenity, an acceptance that some more powerful forces than ourselves exist in the universe.  In effect, it is a mindset of humility, that we humans are not all powerful and all knowing.  Having faith is said to be a virtue.  Perhaps the virtue lies in the humility.
