What we think and then speak about ourselves (and others) can, with repetition, become hard-wired in our brains. This function, of which you may be familiar, is neuroplasticity. It’s super helpful with new work tasks, habit formation, and learning to play an instrument, for instance. The tricky thing about neuroplasticity is that it also is engaged when we repeat things that aren’t necessarily true about how we see ourselves or the world around us.

I follow Erika, a Christian neuroscience coach, on Instagram and Facebook. She recently posted a clear and practical guide to how we can consciously rewire our brain, especially when we’ve allowed negative (essentially untruthful) thoughts and comments take us to a dark place.

She should write a blog or Substack, but I haven’t found one yet. So below please find her well-studied take on “mind over matter (brain)”.

Erika writes: “Neuroscience shows us that: thought + emotion + repetition strengthens a neural pathway.”

She writes for Christians, but honestly, her 8 practices for rewiring our brains are noteworthy for anyone desiring to clear their thinking:

Notice the thought. Think about what you’re thinking about. At times we say things that if checked and sorted we know aren’t true; they are just how we feel at the moment. Not facts but feelings.
Identify the lie. Because of repetition, you may have thoughts that have taken up residence in your brain for so long (neuroplasticity), they seem true. You may need help, through prayer or with a trusted friend, to assess whether you have held onto a lie – about yourself or others.
Take the thought captive. One of my favorite Bible verses is 2 Corinthians 10:5 – “We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ.” Even if a thought or opinion has long been lodged in our minds, we don’t have to preserve it. With help from God or a friend, we can acknowledge a thought that is simply not true and begin the work of isolating it and ridding it from our minds. Rewiring our brain and altering a neural pathway.
Replace the lie with God’s truth. What an amazing guide for life is the Word of God! Wisdom for all of us. If you aren’t a believer, sort out what is really true vs. what has taken up squatter’s rights in your brain – hurting you rather than healing you. For Christians, we look for what is true in the Bible and replace the lie with the truth. It will require its own repetition to rewire our thinking. So worth it. “Is not my word like fire, declares the LORD, and like a hammer that breaks the rock in pieces?” – Jeremiah 23:29
Preach the truth to yourself. When a lie sets up residence in our brains, we have to use repetition to unseat it. Speaking what is true over the lie will put neuroplasticity in a higher gear. I love what Erika says here: “Your mouth reinforces what your mind believes”.
Keep renewing your mind. The old cortisol-filled thoughts aren’t going to go away easily. When they rise it, remember to speak/think what is actually true. The negative thoughts will fade. The Bible talks about “renewing the mind” (Romans 12:2) It is an ongoing practice.
Stay consistent when nothing seems to change. Again, those negative thoughts, those lies, may have embedded over years. The neural pathways are strong. Don’t be discouraged that change takes time. “Don’t mistake slow progress for no progress.” I’m a visual learner. Sometimes for me, it takes written cues on my keyboard, in my journal, on my kitchen counter, in my car. [OK, I can be a slow learner, too.] So thankful for truth that sets my captive brain free!
Build a Godly fortress in your mind. If you have dark days or you struggle with thoughts that overwhelm you, if you can’t resist speaking out contempt for yourself or others, you need to build fortification against such thoughts which turn into words. When we allow our brains to be wired with negative, hateful thoughts, we can rid ourselves of those thoughts. However, we also have to replace them with what is true (Matthew 12:43-45). Building a fortress takes work, but, over time, it is that amazing rewiring of our neural pathways and setting in motion a very different neuroplasticity. So worth the work!
