Vos offers insightful comments on the relation revelation has to redemption:
“Revelation is the interpretation of redemption; it must, therefore, unfold itself in installments as redemption does. And yet it is also obvious that the two processes are not entirely co-extensive, for revelation comes to a close at a point where redemption still continues. In order to understand this, we must take into account an important distinction within the sphere of redemption itself. Redemption is partly objective and central, partly subjective and individual. By the former we designate those redeeming acts of God, which take place on behalf of, but outside of, the human person. By the latter we designate those acts of God which enter into the human subject. We call the objective acts central, because, happening in the centre of the circle of redemption, they concern all alike, and are not in need of, or capable of, repetition. Such objective-central acts are the incarnation, the atonement, the resurrection of Christ. The acts in the subjective sphere are called individual, because they are repeated in each individual separately. Such subjective-individual acts are regeneration, justification, conversion, sanctification, glorification. Now revelation accompanies the process of objective central redemption only, and this explains why redemption extends further than revelation. To insist upon its accompanying subjective-individual redemption would imply that it dealt with questions of private, personal concern, instead of with the common concerns of the world of redemption collectively. Still this does not mean that the believer cannot, for his subjective experience, receive enlightenment form the source of revelation in the Bible, for we must remember that continually, alongside the objective process, there was going on the work of subjective application, and that much of this is reflected in the Scriptures. Subjective-individual redemption did not first begin when objective-central redemption ceased; it existed alongside of it from the beginning.”
