What is the primary act of faith? It is not the acceptance of certain propositions, although it cannot exist apart from the belief of the propositions of the gospel. Faith is essentially an entrustment to Christ as Lord and Saviour. It is self-commitment to him. It is not the belief that we have been saved, not even the belief that Christ died for us, but the commitment of ourselves to Christ as unsaved, lost, helpless and undone, in order that we may be saved.  [Murray’s emphasis.]
