That price of expiation

 “A sacrifice of expiation is one whose object is to appease the wrath of God, to satisfy his justice, and thereby wipe and wash away the sins, by which the sinner being cleansed and restored to purity, may return to favor with God. . . . And, indeed, it was an astonishing display of the wrath of God that he did not spare even his only begotten Son, and was not appeased in any other way than by that price of expiation.” ~John Calvin
