The Progressive Nature of Sin
In life there are many cases where events do not happen suddenly but instead over a steady progression of time. This ebbing change may lead to cultural, political, or some other form of upheaval, which is a great shift taking several very small steps. This is also true of many who engage willfully in sinful practices. It is not common for someone to dive into the deepest depths of depravity, but to instead follow a path which, by attrition, ends oneself in the exact same place.
