[S]anctification is not a new thing, but simply the unfolding, by the operation of the Spirit, of something already present. It is God's justifying verdict itself which sanctifies. . . .
It is precisely because God waits for no guarantees but pardons out-and-out, because He dares to trust a man who has no claim or right to trust at all--it is because of this that forgiveness regenerates, and justification sanctifies.
--James S. Stewart, A Man in Christ: The Vital Elements of St. Paul's Religion (New York: Harper, 1935), 258, 259-60
