She is not just cured. She is set free. Immediately her talk is praise, and no doubt her self-talk is praise also. Jesus changed her focus. He changed her focus from herself to God.
Life is difficult.
It is easy to stay focused on our difficulties. Jesus wants to set us free from crippling self-talk from beating up on ourselves. He wants to replace it with praise. It needs to be simple because I may be driving down the street. I repeat it as long as it takes to replace brooding with praise.
