Belief leads to behavior
Well now that would depend on how you defined 'belief'.If you defined it as something along the lines of mere mental assent you probably wouldn't agree that it effects behaviour that much.Hence the label...'easy-believism'.Many seem to think exactly that and that the work of God is altering your behaviour.It's not necessarily what you say you believe or even what you think you believe that will determine what you actually believe.It's what you do that will tell others and yourself what you really do believe.
A long,hard,brutally honest look at the wretched man in the mirror will quickly reveal why the "work of God" is to believe.
