and that "the chastisement of our peace was upon him" (Isa 53:5).
And again "the just died for the unjust" (1 Peter 3:18).

Now then, if he presented himself as a common person to justice,
if God so admitted and accounted him, if also he laid the sins
of the people, whose persons he represented, upon him, and under
that consideration punishes him with those punishments and death,
that he died. Then Christ in life and death is concluded by the
Father to live and die as a common or public person, representing
all in this life and death, for whom he undertook thus to live,
and thus to die. So then, it must needs be, that what next befalls
this common person, it befalls him with respect to them in whose
room and place he stood and suffered. Now, the next that follows,
is, "that he is justified of God": That is, acquitted and discharged
from this punishment, for the sake of the worthiness of his death
and merits; for that must be before he could be raised from the
dead (Acts 2:24): God raised him not up as guilty, to justify him
afterwards: His resurrection was the declaration of his precedent
justification. He was raised from the dead, because it was neither
in equity or justice possible that he should be holden longer
there, his merits procured the contrary.

applieth God's justifying of Christ to himself; and that rightly
(Isa 50:8, Rom 8:33,34). For if Christ be my undertaker, will stand
in my place, and do for me, 'tis but reasonable that I should be
a partaker: Wherefore we are also said to be "quickened together
