I'm struck by how the first sentence implies that sanctification gives birth to a life of dependency on the Spirit.  It makes me again think about the terms we use to describe discipleship, particularly the current popularity of the term "apprentice", which, at least as I understand it, does not lead to a life of "perpetual....and inherent lack of self-sufficiency."  Instead, the idea of apprenticeship eventually leads to a life where one no longer needs the aid of the Master, once one is fully "skilled." 

And this idea of a "perpetual....and inherent lack of self-sufficiency."  Do we have any category of relationship that even approaches this?  Even the parent-child relationship ends and changes into an adult to adult relationship, albeit with an element of honor and respect for one's parent (assuming the relationship is a healthy one).

I am just glad my sanctification does not have anything to do with my self-sufficiency, because I sure ain't sufficient.
