1. The Coherence

Debt] By debts sins are meant, as it is in (Luke 11:4), and they are so called, because of the resemblance between them. For even as a debt does bind a man, either to make satisfaction, or else to go to prison: so our sins bind us either to satisfy God's justice, or else to suffer eternal damnation.

Forgive] To forgive sin, is to cover it, or not to impute it (Psalm 32:1). And this is done when God is content of his mercy to accept the death and passion of Christ as a sufficient payment and ransom for man's sins, and so to esteem them as no sins. And here under this one benefit of remission of sins, all the rest of the same kind are understood, as justification, sanctification, redemption, glorification, etc.
