“I tell you, her sins, which are many, are forgiven — for she loved much” Luke 7:47
Even when we can’t forgive ourselves, God has given us the great gift of HIS forgiveness. That is why the Proverbs 31 woman was able to laugh at the future. Whatever it is you can’t forgive yourself for, consider that you are carrying a needless burden. This is true whatever it is, whether the way you have treated others, or even going into debt.
If God has forgiven you, how can you do less?
Because God has forgiven us, we have the obligation to be like Him and forgive others. The Proverbs 31 woman spoke wisely and kindly to others. No doubt, she was able to do this because she had forgiven them any wrong they may have done to her.
Pray about it. Ask God to take it and bless it and use it for His glory
