“The central soteriological reality is union with the exalted Christ by Spirit-created faith. That is the nub, the essence of the way or order of salvation for Paul. The center of Paul’s soteriology, at the center of his theology as a whole, then, is neither justification by faith nor sanctification, neither the imputation of Christ’s righteousness nor the renewing work of the Spirit.”
Richard Gaffin: By Faith, Not By Sight: Paul and the Order of Salvation, Paternoster, 2006, p. 43.
