Lord, forgive our debts (Matt 6:12)

How much "debts" do we owe our Lord? and how much our debtors owe us. We usually associate 'debts' with monetary term. If it is monetary term, then how much do we owe HIM, can we repay HIM, and if it is not monetary term, then what are the "debts" that we owed HIM? Perhap our Lord Jesus may be referring to tithes and offering.
"Will a man rob God? Yet you have robbed Me! But you say, 'In what way have we robbed You?' In tithes and offerings. (Mal 3:8).
Be it monetary or others. "Then one poor widow came and threw in two mites, which make a quadrans. So He called His disciples to Himself and said to them, "Assuredly, I say to you that this poor widow has put in more than all those who have given to the treasury"; (Mar 12:42). It is our heart that our Lord looked at. We own HIM our whole life. All i can say is : Lord, forgive my debts and forgive our sins. I will end with this verse :
And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you. (Eph 4:32)
