There is a daily war between our sinful nature and our redeemed nature. We defile our spirits effortlessly in the attempt to elevate ourselves in our own eyes and in the eyes of other defiled spirits. In vanity, mirrors are tools for pride-elevating positive feedback, but Confession turns mirrors into agents of truth and strips the vanity from our eyes to see our sin as God sees it.
And forgive us our debts...
I've always found it interesting how the different English translations render the word "debts." Some say "trespasses;" some say "sins." In each of these different renderings, the message is conveyed that we have something grevious about ourselves that needs the forgiveness of God. The usage of the word "debts" in the King James helps us to understand that each moment of our sinful lives is lived on borrowed time and mercy from the Creator God. The priority of this clause should not be missed. Jesus' directive is for us to recognize that we have sinned against God before we have sinned against others.
...as we forgive our debtors.
As believers then, our lives are then spent "redeeming the time," (Colossians 4:4-6) paying back the time we spent in rejection of God by paying it forward our forgiveness to those who do not believe and have done injustice to us. Let's look at forgiveness as the wisdom to create justice from injustice and establish the peace of our Lord. Such forgiveness is indeed divine.
