It’s a kingdom principle. You have been forgiven, therefore forgive.
I wonder if you consider yourself someone who has been forgiven much or just a little. Either way it doesn’t matter, the principle stays the same. You have been forgiven, therefore forgive.
To accept forgiveness but then hold a grudge (lets call that what it is, unforgiveness) towards another is a dangerous position to be in. Jesus said that everyone who does not freely forgive from their heart offends God [Matthew 18:23-35]. Forgiveness received by us should produce forgiveness given by us. I certainly don’t want to put myself in a place where I am offending God. Surely that can only end badly.
Here’s what I have learned about some of the the instructions Jesus gives us: Just because it isn’t easy doesn’t mean we shouldn’t do it.
I need to remember to not act according to my emotions but according to my faith as a Christian. Forgiveness is a decision to cancel a debt. It’s more than just trying to forget it, I must cancel it.
Pray. Ask God to help you. Give it over to Him. Let Him deal with it. Choose to forgive, to cancel it and then get on with the rest of your life. I recognise that this might seem too simple for many of us but I think sometimes that can be the problem, we over think it, we don’t want to let it go, we feel right in our feelings but at the end of the day those things don’t really matter. Jesus tells us to forgive.
We have been forgiven, therefore forgive.
[If you struggle with this issue then find a Christian that you can talk & pray stuff through with. Just do whatever you need to do to get things sorted]
