Abstract
If humans are sanctified by a triune God, part of the success of spiritual formation depends on understanding how one’s agency depends upon the Trinity. Some sanctifying actions require causal notions like “obedience,” “yielding,” “participation,” and “cooperation.” So, how is a Christian going to understand them? The purpose of this paper, then, is twofold: develop a model of agency that provides an adequate account of understanding how one’s agency depends upon the Trinity; and explain how this model can increase the reliability of one’s perceptual capacities to perceive one’s agency cooperating with the Trinity in acts of sanctification.
