“The liberty of believing or of not believing is placed in free choice.  In Deuteronomy, it says: ‘Look!  I have set before your face life and death, good and evil.  Choose for yourself life, that you may live’ [Deut. 30:19].  Also in Isaiah: ‘And if you are willing and hear me, you will eat the good of the land’ [Isa. 1:19].”
