“The Bible presents sin by way of major concepts, principally lawlessness and faithlessness, expressed in an array of images: sin is the missing of a target, a wandering from the path, a straying from the fold. Sin is a hard heart and a stiff neck. Sin is blindness and deafness. It is both the overstepping of a line and the failure to reach it—both transgression and shortcoming.
Sin is a beast crouching at the door. In sin, people attack or evade or neglect their divine calling. These and other images suggest deviance: even when it is familiar, sin is never normal. Sin is disruption of created harmony and then resistance to divine restoration of that harmony. Above all, sin disrupts and resists the vital human relation to God.”
