Now no one despises the supreme Principle or its command in itself, but only because such a person either wants to acquire or fears to lose something other than God. This is why all actual sin may be traced back to these two roots, namely fear and love. They are the roots of evil deeds, even though they are not equally primary.
For all fear has its origin in love, since no one is afraid of losing something unless that person loves it.
