What should we understand in the Lord's Prayer under the name of our debts?
Our sins.
Why are sins called debts?
Because we, just as we received everything from God, must give everything to God, that is, submit everything to His will and law: if we do not do this, then we remain debtors to His justice.
And who are our debtors?
People who did not give us what they should have given according to God’s law - for example, did not show love, but enmity.
How, with God's justice, can we hope to have our debts forgiven?
Through the intercession of Jesus Christ.
For there is one God, and one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all (1 Tim. 2:5-6).
What happens if we ask God for forgiveness of our sins, but we ourselves do not forgive others?
We will not receive forgiveness either.
If you forgive people their sins, then your Heavenly Father will also forgive you, and if you do not forgive people their sins, then your Father will not forgive you your sins (Matthew 6:14-15).
Why doesn't God forgive us when we don't forgive others?
Because through this we turn out to be evil, and thereby remove the goodness and mercy of God from ourselves.
Therefore, what kind of disposition do the words of the Lord’s Prayer require from those praying: “And we forgive our debtors?”
They absolutely demand that the one praying should not have any enmity or anger, but have peace and love with everyone. So, if you are bringing your gift to the altar and there you remember that your brother has something against you, leave your gift there before the altar, and go first and be reconciled to your brother, and then come and offer your gift (Matthew 5:23-24).
But what should I do if the one who has something against me cannot be found soon, or if he turns out to be unwilling to reconcile?
In this case, it is enough to reconcile with him in the heart, before the eyes of the All-Seeing God.
If possible, be at peace with all people (Rom. 12:18).
