Man and Sin by Piet Schoonenberg (1964) 2.2 CW

Summary of text [comment] page 76

Yet, it does not destroy our human nature. It does not destroy our freedom.

Like grace, sin influences our nature [dispositions] in so far as it is at the disposal of the person as the seat of freedom [consciencespecified].
