sins are redeemed by repentance, i.e. the obligation or guilt is removed, because God forgives those who repent, as it is written in Ezek. 18, 21. 22. Nor are we to infer from this that He forgives on account of works that follow, on account of alms, but on account of His promise He forgives those who apprehend His promise. Neither do any apprehend His promise, except those who truly believe, and by faith overcome sin and death. These, being regenerated, ought to bring forth fruits worthy of repentance, just as John says, Matt. 3, 8. The promise, therefore, was added: So, there will be healing for thy offenses, Dan. 4, 24. [Daniel does not only demand works, but says: Redeem thy sins by righteousness. Now, everybody knows that in Scripture righteousness does not mean only external works, but embraces faith, as Paul says: _Iustus ex fide vivet_? The just shall live by his faith, Heb. 10, 38. Hence, Daniel first demands faith when he mentions righteousness and says: Redeem thy sins by righteousness, that is, by faith toward God, by which thou art made righteous. In addition to this do good works, administer your office, do not be a tyrant, but see that your government be profitable to your country and people, preserve peace, and protect the poor against unjust force. These are princely alms.] Jerome here added a particle expressing doubt, that is beside the matter, and in his commentaries contends much more unwisely that the remission of sins is uncertain. But let us remember that the Gospel gives a sure promise of the remission of sins. And to deny that there must be a sure promise of the remission of sins would completely abolish the Gospel. Let us therefore dismiss Jerome concerning this passage. Although the promise is displayed even in the word redeem. For it signifies that the remission of sins is possible that sins can be redeemed, i.e., that their obligation or guilt can be removed, or the wrath of God appeased. But our adversaries, overlooking the promises, everywhere, consider only the precepts, and attach falsely the human opinion that remission occurs on account of works, although the text does not say this, but much rather requires faith. For wherever a promise is, there faith is required. For a promise cannot be received unless by faith. [The same answer must also be given in reference to the passage from the Gospel: Forgive, and you will be forgiven. For this is just such a doctrine of repentance. The first part in this passage demands amendment of life and good works, the other part adds the promise. Nor are we to infer from this that our forgiving merits for us _ex opere operato_ remission of sin. For that is not what Christ says, but as in other sacraments Christ has attached the promise to an external sign, so He attaches the promise of the forgiveness of sin in this place to external good works. And as in the Lord's Supper we do not obtain forgiveness of sin without faith,
