How immense the difference between the two propositions—that our iniquities were laid upon Christ, that in his own person he might expiate them, and that they are expiated by our works; that Christ is the propitiation for our sins, and that God is to be propitiated by works. . . . Those who rest satisfied with petty satisfactions form too contemptible an estimate of the justice of God, and little consider the grievous heinousness of sin, as shall afterwards be shown. Even were we to grant that they can buy off some sins by due satisfaction, still what will they do while they are overwhelmed with so many sins that not even a hundred lives, though wholly devoted to the purpose, could suffice to satisfy for them?
