I’m currently reading “You’re Going to Be Okay: Encouraging Truth Your Heart Needs to Hear, Especially on the Hard Days,” by Holley Gerth. She had the clearest understanding of renewing the mind that I’ve ever read.

“The other day I pulled up to a railroad crossing just as a train came barreling through it. At the last minute, it screeched to a halt and an engineer jumped out of the first car. He ran to the track, made some adjustments, and hopped back in to continue the journey. As I looked closer, I could see exactly what he’d done – switched the track.

“Our thoughts are a lot like that train. They go speeding through life, and we don’t give much intentional focus to them. They run on automatic based on past experiences and how we’ve taught ourselves to respond to different situations. Every time you react a certain way, your brain makes a note of it. That means the thoughts you think most have the strongest tracks, and your mind automatically goes there.

“When you decide to ‘renew your mind,’ it means stepping off the train and switching the tracks. We have to do this again and again. Then at some point, your brain realizes that this is the new normal response, and it goes there automatically.”

The mind is renewed one area at a time, as we apply this process. Our thinking changes as we apply “the mind of Christ” to our circumstances or sin pattern. Then we do it again and again, until our thinking in this area conforms to the Word of God automatically. Our new normal response is no longer conformed to the ways of this world. Our thoughts in this area now line up with the “good and acceptable and perfect” will of God.
