I just invented a new Kline-esque term in “cross-transfer,” but I trust it gets at the point of what Vos is saying in The Pauline Eschatology on p. 48.
The cross is represented as effecting an absolute separation between two worlds, so as to have cut loose the Apostle from the world to which he at first belonged, and having transplanted him into another.
How seriously do we, as believers, take Paul’s language?  I know that too often I consider myself a partaker of this present evil age.  Surely I sin and the old man is daily being mortified through the Spirit’s work in me, but I don’t consciously think of having been transplanted into the age-to-come.  But as Christians, we must also look forward to that reality – not simply as a future.  We have been transferred to a new life at the cross and we must live upon the foundation of that truth.
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
