Although justification is pronounced objectively in the resurrection (Rom. 4:25), it is received subjectively through faith that hears the promise: “For with the heart one believes and is justified, and with the mouth one confesses and is saved . . . [And] faith comes from hearing, and hearing through the word of Christ” (Rom. 10:10, v. 17). No one can have faith apart from the electing and regenerative work of the Spirit (1 Cor. 2:14, 12:3, Gal. 3:2). Christ makes intercession on behalf of believers in heaven, on the basis of his sacrifice on the cross (Rom. 8:34). The Holy Spirit, the who is the spirit of the Son (Gal. 4:6), makes the fruits of Christ’s intercession – justification – present in the heart of the believer (Rom. 10:6-13) through the hearing of the Word (Rom. 10:7, Gal. 3:2). Much as the elect representational persons stood in the place of Israel in the Old Testament as mediators, so too Christ and his righteousness stand in for the unrighteousness of the unbeliever through an act of imputation (Rom. 3:25, 4:9, v. 22, 8:10, 1 Cor. 1:30, 2 Cor. 5:21, Gal. 3:6, Phil. 3:9). The concept of representation that we see in the Old Testament therefore makes sense of Paul’s language of imputation in atonement and justification. In atonement, Christ is imputed with human sin, and in justification humans are imputed with Christ’s righteousness (2 Cor. 5:21).
It is important to notice that Paul uses the term eschatological term “justification” for what happens proleptically (in the future) to believers in the present. As we observed earlier, for Second Temple Jews, at the end of time God would “justify” (judge righteous and vindicate) those who had adhered to the covenant and usher them into the kingdom. For Paul, Christ is the object of election and justification. He is one the one who has adhered to the covenant and be vindicated on the eschatological day of his resurrection. Therefore, in the present believers can proleptically receive through Christ what they will receive at the end of time through faith in the promise (i.e., election and justification). This is because the eschaton has already happened for Christ, and therefore when believers enter into him the eschaton happens to them as well. Outwardly, believers remain in the current age weighed down by sin and death, but in the inner being they already have been ushered into the kingdom of the resurrected: “But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness” (Rom. 8:10).
