“The fathers [the Old Testament saints] knew the promise about the Messiah, that God for the Messiah’s sake had chosen to forgive sins. Therefore, since they understood that Christ would be the price given to pay for our sins, they knew that our own works are not a sufficient price for so weighty a matter. Accordingly, they enjoyed free mercy and the forgiveness of sins by faith, just like the saints in the New Testament." "Psalm 130:3 “If You, Lord, should mark iniquities, O Lord, who shall stand?” Here David acknowledges his sins and does not speak of his merits. He then adds: “But there is forgiveness with You” (verse 4). Here David comforts himself by his trust in God’s mercy, and he quotes the promise: “My soul waits, and in His Word I hope,” (verse 5), i.e., because You have promised the forgiveness of sins, I am supported by Your promise. Therefore the [Old Testament] fathers too were justified, not by the law, but by God’s promise and by faith.” Church HistoryThe Reformation Book:The Apology of the Augsburg Confession Source: The Apology of the Augsburg Confession
