Resurrection and Imputation
Christ was delivered over for our trespasses, but raised for our justification. By virtue of faith union with the resurrected Christ, all of his meritorious active and passive obedience, all that he is as crucified and raised unto justification, is reckoned to believers. Thus, in the deepest structures of Pauline soteriology we grasp the perfect convergence of union with Christ and the imputation of righteousness. Christ's own resurrection is his justification, and by virtue of faith union with the resurrected Christ, believers are justified in Christ (by means of faith) and receive his righteousness.
