Over lunch (triple-decker peanut butter and jelly, to be precise), I ran across a paragraph that reminded me of an ongoing conversation with a good friend:
“The central image the Wuthnow uses to describe twenty- and thirty- somethings, when it comes to life generally and religion specifically, is ‘tinkering.’ They are, he says, ‘a generation of tinkerers.’ These are a people who pragmatically piece together a jumble of disconnected and sometimes contradictory bits of belief and practice as they—supposedly autonomous individuals—see fit. Tinkering, Wuthnow argues, is a style or habit or strategy driven ultimately by the many economic and cultural uncertainties that characterize American society in recent decades. Tinkerers are resourceful and adaptable but also often live makeshift and less than fully coherent lives.” 
Tinkering already assumes the disjunction of trust and truth. Trust is an impossibility in the tinkering life because truth is always something that I (a tinkerer) possess or assemble myself, truth is always contained within my own experience, and therefore there is no room for trust. If trust becomes a truth, it is appropriated as a subjective feeling of dependence, rather than as submission or obedience. Tinkering is a way to remain self-contained, self-controlled, and self-directed. Like every Babel, it tends toward confusion and fragmentation—and leaves every tinkerer alone.
This is the spiritual expression of the American Dream, the entrepreneurial spirit, and the capitalist manifesto—work hard and don’t let anyone tell you what to choose. You can make it!
This deep in history, there seems to be something of the tinkerer in every theologian, but the best theologians self-consciously work within a tradition. Christian theology is born out of the depths of prayer, not out of a sense that it would be nice to have a habit of praying, or that praying might make me a deeper and more sensitive person. This means that Christian theology already presupposes trust as its resting point, the precarious stance from which the whole gospel is proclaimed.
