“I can elect to change all thoughts that hurt.”
This ability to focus your mind is your key: your ability to decide what to direct your attention towards, and, perhaps even more importantly, what to not direct your attention towards. That means that I look at the thoughts that come up, and when when a thought is not making me happy, I acknowledge it and decide I do not want it. Then I ask the Holy Spirit to heal my mind regarding that thought.
You can choose which thoughts to think. You are not a victim of the destructive thought loops the monkey mind has on sale. Pass them by and instead focus on loving thoughts, peaceful thoughts, on ideas that spell freedom and beauty, focus on the flow of inclusion and expansion. In short: focus on glory and nothing else. It abounds in you and it abounds in creation.
