Asking if something works, one needs to be aware if the presuppositions are coming from a mechanical bias. Similar to purchasing a car, the buyer wants to know if all the features do what they are supposed to do. Does the engine run? Does the AC cool? Will the transmission shift? All these questions are fair and reasonable.
But a relationship with an automobile is different than one with a living, dynamic, organic being. And I believe we have melded the two ideas together so that there is no division any more.
Our culture has blurred our distinctions of mechanism and relationship. Marriage is a prime example. The current version not cutting it for you? Trade the old partner in for a new sportier model. Take the shiny one out for a sex drive and put it through all the gears. I don’t know; this one’s just not working for me.
What person wants to be treated that way? Certainly not the one to which I am married.

But this is where one must take account of a fundamental paradigm.
Our quest for answers and resolution has jeopardized our ability to adequately understand the Divine. God as a Person will be comprehended differently than God as a Brand.
