In the “our Father” [the Lord’s Prayer], we not only pray for the forgiveness of sins, but also for daily bread and food. Thus, we confess with this that we cannot only not make payment for our sin before God the Lord, but that we are also unable to earn our daily bread. Instead, we have to beg and petition God’s mercy for both the forgiveness of sins and daily bread. We find such grace and mercy from God only in and through Christ. So then, just as we ask for and obtain forgiveness of sins through Christ, so also we obtain our daily bread and food through him.
– Johann Gerhard, Postil for the Fourth Sunday in Lent
