{For our justification} (dia t(886e) dikai(9373)in h(886d)(936e)). The
first clause (paredoth(8820)dia ta parapt(936d)ata) is from  Isa
53:12 . The first dia with parapt(936d)ata is probably
retrospective, though it will make sense as prospective (to make
atonement for our transgressions). The second dia is quite
clearly prospective with a view to our justification. Paul does
not mean to separate the resurrection from the death of Christ in
the work of atonement, but simply to show that the resurrection
is at one with the death on the Cross in proof of Christ's
claims.
