 This model of faith as a kind of knowledge, certain and welcome, exhibits faith as essentially something to be received, something delivered by the proper functioning of a special cognitive faculty. Nevertheless, the model may admit a practical component, since an active response is required for reception of the divine gift. Such a practical component is implied by the real possibility that faith may be resisted: indeed, Christians may hold that in our sinful state we will inevitably offer a resistance to faith that may be overcome only by God’s grace. It is, however, a further step for persons of faith to put their revealed knowledge into practice by trusting their lives to God and seeking to obey his will. On this ‘special knowledge’ model of faith, however, this activity counts as ‘acting out’ one’s faith rather than as a part of faith itself. Persons of faith thus act ‘in’, ‘through’ or ‘by’ faith: but, on this model, their faith itself is the welcomed revealed knowledge on which they act.
