It also got me to start thinking and praying about others in my life that I haven't really forgiven. I thought I was the forgiving type, but God soon revealed a few people that I was still holding onto forgiveness with.
He also showed me how not forgiving was a consuming and destructive force. It was not advancing His kingdom. In fact it was doing the opposite. Besides that, it was taking precious time away from more important things in life.
I challenge you:
Is there anyone you need to forgive?
Were you abused, forgotten, lied to, cheated on, ...?
Is there anyone you need to ask forgiveness?
Did you gossip, lie about, deceive, neglect, ...?
Ask God to show you whom you need to forgive and ask forgiveness of.
