This installment is a bit lengthy, but in my opinion worth the time. It is Ridderbos’ concluding paragraph in his treatment on the parousia, and it is the final paragraph for the entire book. Enjoy:
With this twofold point of view, namely,  that God will be all and in all and  that we shall always be with the Lord, everything has really been said thta can be said on the consumation commencing with Christ’s parousia. Paul’s attention for what is to be in the coming kingdmo is always concentrated on this twofold viewpoint. This does not alter the fact that he gives expression to the content of this life with Christ and the “all” with which God will fill all in various ways: it is being saved by his life (Rom 5:10); salvation with eternal glory (2 Tim 2:10); honor and immortality (Rom 2:7; 1 Cor 15:42ff; 2 Tim 1:10); eternal glory (2 Cor 4:17); seeing face to face (1 Cor 13:12); fulfillment of righteousness and peace and joy in the Holy Spirit (Rom 14:17); perfect knowing (1 Cor 13:12). All are concepts of salvation, descriptions of God’s imperishable gift, every one of which has its own context, origin, and nuance, and offers its own special contribution in order to make what is unutterable (2 Cor 12:4) nevertheless known even now in part. But all these words, likewise as qualifications of the life of the consummation, receive their particular meaning and content only from the gospel of the revelation of the mystery preached by Paul in an incomparable multiplicity of aspects.
