Forgive one another.
Since God has forgiven you, He expects you to forgive others, with His help. Don’t wait until you feel like forgiving people who’ve hurt you; you likely never will. Instead, decide to forgive, and your feelings will eventually follow as God changes your heart through the forgiveness process.
Understand that forgiveness doesn’t mean excusing wrong behavior. It simply means that you’re entrusting the situation to God. Even if the people who’ve wronged you don’t apologize and repent, choose to forgive them anyway, knowing that by doing so you’ll be giving God the gift of your obedience and freeing yourself from the poison of bitterness.
