Problems with the One-Nature View
Properly delineated, the two-nature view can accurately and correctly represent the Bible’s teaching on regeneration and sanctification, but so can the one-nature view, if it is properly delineated. An advantage for the two-nature view—and thus a minor difficulty for the one-nature view—is that the two-nature view more easily describes the believer’s struggle with sin. As we have previously observed, one-nature advocates usually end up using two-nature terminology even though they disavow the term nature. A potential and much more serious problem for the one-nature view can arise if that one nature is not carefully defined. For instance, Warfield says: “For the new nature which God gives us is not an absolutely new somewhat, alien to our personality, inserted into us, but our old nature itself remade.”1 Thus Warfield can call the believer’s one nature, the new nature. But, of course, Warfield is careful to explain that something old remains in that new nature.
