If pain sometimes shatters the creature’s false self sufficiency, yet in supreme Trial or Sacrifice’ it teaches him the self-sufficiency which really ought to be his – the ‘strength which, if Heaven gave it may be called his own’: for then, in the absence of all merely natural motives and supports he acts in that strength, and that alone, which God confers upon him through his subjected will. Human will becomes truly creative and truly our own when it is wholly God’s, and this is one of the many senses in which he that loses his soul shall find it. In all other acts our will is fed through nature, that is, through created things other than the self – through the desires which our physical organism and our heredity supply to us. When we act from ourselves alone, that is, from God in ourselves – we are collaborators in, or live instruments of creation: and that is why such an act undoes with ‘backward mutters of deserving power’ the uncreative spell which Adam laid upon his species.
