If we believe in something, we place our faith in it, and thus we are changed in our own sense of Being. Marcel asserts that faith implies humility and prayer. Humility is a mode of being which includes a recognition by the self of its own finiteness, and an affirmation of the sacred. Prayer is a form of spiritual communication with God. Authentic prayer is neither a selfish request, nor a mechanical recitation, but is a way of uniting ourselves with God.
Freedom is the ability to act significantly.
The free act is significant, because it contributes to making us who we are as human beings. Freedom is not merely doing whatever we want. Freedom is not merely the ability to make an arbitrary choice, because there is no freedom if everything that can be chosen is insignificant. Freedom is the ability to make significant choices. Marcel believes that this freedom is given to us by God.
