The song is about phil being tempted for somthing and the craving is like no other and even though he wants it so bad he will stick to what he knoes is true and no follow througb with it cuz he knows what the concequesnces are, and even when he doesn't want to beleive it he still sticks to it. There is definatly some christian motives in this song due to trial of temptaion and dealing with sin. And this calling could refer to being born again to a new hope, that he found a way to over come it, meaning god or somthing, but hedefinatly claimed victory for sure. This song I can relate cuz me being a cristain myself this song describes exactly how difficult it can be with facing temptation, cuzz with me it dealt with purity struggles, but with jesus, I have victiry.
