John Murray, with good reason, argues that obedience is the most inclusive concept available to us for describing the redeeming work of Christ (Redemption Accomplished and Applied, p.19). Other categories such as sacrifice and satisfaction cover some of the data, but obedience is by far the most comprehensive.
It is also, of course, utterly biblical. Christ came pre-eminently as the Servant, in fulfilment of Isaiah’s prophecy (especially Is. 52:13- 53:12). In accordance with this, he saw himself as one who had come not to do his own will, but the will of the Father who had sent him; and at the end of his life his claim was simply that he had finished the work given him to do (John 17:4).
