"In earlier times it did not take faith to believe that God existed--almost everybody took that for granted. Rather, faith had to do with one's relationship to God--whether one trusted in God. The difference between faith as "belief in something that may or may not exist" and faith as "trusting in God" is enormous. The first is a matter of the head, the second a matter of the heart. The first can leave us unchanged, the second intrinsically brings change."
