Rewiring Your Brain

When Moses died, Joshua suddenly found himself leading God’s people into the Promised Land. A land filled with giants, bitter enemies, and overwhelming responsibility. God’s word to Joshua in that moment wasn’t a battle plan to defeat the enemy. It was to memorise scripture.

“Be strong and very courageous… do not turn from it to the right or the left… this Book of the Law shall not depart from your mouth; meditate on it day and night… then you will be prosperous and successful.” (Joshua 1.7-8)

God tells Joshua not just to read and obey His Word but to meditate on it. To “meditate” doesn’t just mean to think quietly. God is not telling Joshua to empty his mind of all conscious and subconscious thoughts.

The Hebrew word for meditation, haga, means to rehearse, speak, and deeply reflect. God was telling Joshua: fill your mind and your mouth with my Word until it shapes the way you think and live. Knowing and rehearsing God’s Word would be the key to Joshua’s success.

I was recently reading an article on neuroplasticity, and it explained how our brains are constantly shaped by what we repeatedly focus on. The more we think a certain thought, the more that neural pathway in the brain is strengthened. Over time, those repeated thoughts begin to reshape our brains, influencing how we think and even how we see the world.

That means the thoughts we rehearse—whether positive or negative, true or false—can take root in our minds and influence our emotions, perceptions, habits, and what naturally comes to mind in everyday moments. Whatever thoughts we return to most often are the ones that grow strongest.

Are you starting to see where I’m going with this?

If we’re constantly rehearsing fear, doubt, or lies, those mental pathways don’t stay neutral—they become stronger, more familiar, and more automatic. But when we memorise and meditate on scripture, we’re training our minds to default to God’s voice instead of our own fears. Then, when difficult moments come, we’re more ready to respond in faith and obedience.

Joshua didn’t have time to scroll for encouragement in the middle of battle. The Word had to already be in him. He needed to step into conflict with a bold confidence that God was with him and that he would fulfil his promise to lead his people into the Promised Land.

And the same is true for us. In seasons of testing, we need to be able to draw from biblical truths that will get us through the battle, through the temptations, and through the discouragements.

The other day on the Tube, I found myself overwhelmed with anxious thoughts. So I began quietly rehearsing Psalm 27.1: “The Lord is my light and my salvation whom shall I fear? The Lord is the stronghold of my life of whom shall I be afraid?” And as I meditated on those words, the heaviness in my heart began to lift, and I was swept away with the peace of God.

We need to store God’s Word so deeply within us and rehearse it continually, so that it shapes how we think, how we respond, and how we live. Because when the pressure comes, we won’t always have time to reach for the Bible. We’ll need to reach for whatever is already hidden in our hearts.

How to eat the book

Reading is a lot like eating. 

But then again, so is watching, and scrolling, and listening to your favourite pods. That’s why we talk about consuming content.

The biblical authors talk this way. They speak about God’s word as something you can consume. Ezekiel was told to ‘Eat this scroll…’ and so he adds, ‘Then I ate it, and it was in my mouth as sweet as honey.’ Jeremiah says something similar: ‘Your words were found, and I ate them, and your words became to me a joy and the delight of my heart…’ 

The Psalmist talks about God’s words as desirable and edible: ‘More to be desired are they than gold, even much fine gold; sweeter also than honey and drippings of the honeycomb.’ And again, ‘How sweet are your words to my taste, sweeter than honey to my mouth!’ 

Why is reading (and watching, and scrolling, and listening) like eating?

We know that, at some level, the things we consume become a part of us. That’s true of food, and it’s true of words. They change us, very often in unconscious ways. Everything we are exposed to leaves its mark upon us, affecting how we think about the world and about ourselves. 

This means that you can approach eating and reading in much the same way. You eat regularly (at least once a day), habitually (even when you wish you wouldn’t!), by necessity (or you’ll die), and mostly with enjoyment; it’s sweet to your tastebuds. 

I think that God wants us to read his word in the same way: regularly, habitually, by necessity, and with deep enjoyment.

How should you go about consuming the book?

Of course, there is a maximal approach to studying the Bible. Some people are called to dedicate their whole lives to it, and even then, after years of dedicated study, they will often feel that they have barely begun.

But it can be unhelpful to think about the maximal approach when most people struggle to make any headway in reading the Scriptures. And so, I want to suggest that eating the book should look like the straightforward, daily practice of just reading or listening to the Bible. 

Don’t overthink this so that you paralyse yourself. Just as you manage to pour a bowl of cereal each morning, or buy a meal deal at lunch, or whip up your favourite pasta dish at night, so should you establish a habit of eating the Bible every day – same place, same time, following a manageable reading plan. (I like this one.)

You won’t understand everything. You may not even know what difference it is making at first. But just as eating does you good regardless of whether you understand the biochemistry involved, so does God’s word.

As this habit becomes a part of your life so that you love it and actively look forward to it, you’ll find ways of going deeper. But that’s for later. Right now, just read.

How Do You Read the Bible?

Have you ever read the Bible and felt like you're not ‘getting it’? This feeling can stem from approaching the Bible with a faulty paradigm - a framework or set of expectations that shapes our understanding of reality. Paradigms operate subconsciously, guiding how we interpret and understand our experiences. We all bring paradigms when we read and study the Bible. So, it's helpful to examine ourselves and consider which paradigms we've adopted and whether they're helping us understand God’s Word.

Here are three common but unhelpful paradigms for studying the Bible. All three share a ‘reference book mentality’. They treat the Bible like Wikipedia or a dictionary – a source only helpful for answering our questions. We flip through reference books to find the information we need rather than reading them cover to cover. While the Bible addresses human needs and answers our questions, if we read it like a reference book, we miss out on the story it’s telling.


The Bible Is Not a Theology Dictionary

The first of these ‘reference book’ paradigms says, “The Bible is a theology dictionary.” This paradigm treats the Bible like an expert resource on theological matters: how to structure a church, how to deal with the problem of evil, how to understand Jesus’ humanity and deity, etc.

Reading the Bible like this can be helpful. However, when this becomes the sole way we engage with it, we miss the grand narrative of the Bible, the greatest story ever told. We forfeit the richness of a passage if we reach for it simply to make a broader theological point. The best theologians first seek to understand passages of Scripture in their original context, as part of this greatest story, and then derive theological principles from that understanding.


The Bible Is Not a Moral Handbook

It’s not uncommon for people to appeal to the Bible as the basis for their moral beliefs. An overemphasis, however, trains others who follow Jesus (and those who don’t) to see it primarily as a rulebook.

Of course, deriving moral principles from the Bible is necessary – otherwise, we would arrive at moral preferences without any authority but our own. The Bible itself begins with the question, “Who gets to define what is good, humans or God?”.

But instead of only answering moral questions with a set of rules, the Bible invites people into a dynamic process of forming and aligning their ethics and character with God. For example, Jesus affirms the rule against murder and also teaches his disciples that there is a greater depth to it, that anger and hatred within a person’s heart are akin to murder (Matthew 5:21-22). A rulebook tells people what to do and leaves it at that. Instead, the Bible is designed to cultivate wisdom and purity in us and form us into people who need fewer rules because our character has been formed by God through his word.


The Bible Is Not a ‘Devotional Grab Bag’

At best, this paradigm professes a (true) belief that the Bible exists to connect us to the presence of the living God. But, it also focuses attention only on the ‘feel-good’ sections of Scripture that leave us with a strong emotional sensation. In the process, the devotional grab bag paradigm ends up doing what the other reference book paradigms do – sidestepping the full story of the Bible.


Perhaps the Bible has become stale for you, like flicking through the pages of a dictionary or rulebook. Exposing these three unhelpful paradigms is not meant to leave you deflated but hopeful. God gave us the Bible. He could have given us a theological dictionary, a moral handbook or a devotional grab bag if that is what he thought we needed but, he gave us the Bible: a divine-human book that speaks God's word to his people, telling the greatest story ever told that ultimately leads us to Jesus, the one who has power to change lives.

A New Years Resolution?

Have you given any thought to New Year's resolutions this year? 

I used to be sceptical of them, but over the past few years, I've become more convinced of the value of making resolutions i.e. commitments to pursue specific personal goals. You may not achieve what you hoped, but if you aim at nothing, that's often what you achieve. 

I wouldn't restrict such commitments just to a new calendar year. Instead, I'd encourage you to regularly take time to step back, and assess each aspect of your life (your spiritual life, your relationships, your work, your responsibilities, and patterns of life), and reflect (with the Lord) on how you might need to make adjustments. 

As you're doing that, let me make one suggestion that might be helpful for your walk with God: establish a triplet with a couple of Christian friends.  

Have you got a couple of friends you could commit to meeting regularly (either weekly or bi-weekly), who you'll commit to being honest with, sharing your struggles, confessing your sin, reminding each other of the gospel, and praying for each other? 

I ask, partly because we're starting a Community Bible Reading plan as a church. You're still able to join the WhatsApp group if you'd like to (where we'll share weekly devotional content). You're welcome to follow along individually, but I think you'd get a lot out of forming a triplet with a couple of other folks. Alongside being honest with each other, you could reflect each week on what you've been reading and how you feel like God has been speaking to you through scripture. 

I know some of us in London feel lonely. We cast about, asking, "who are my friends?". One of my main learnings about friendship as an adult is life is full of potential friends. It's simply a matter of who you commit time to. The more you regularly invest time in another person, the better friends you become. So, the question, for 2024, is who will you commit to?  

Others of us feel like we have lots of relationships, but we haven't experienced deep, spiritual friendship like this. There's something incredibly special about choosing to be radically honest with a couple of people, and engaging with the hardest elements of your lives together. 

So, whether you're doing CBR or not, I'd encourage you to find a couple of people (who you might not know so well to begin with), and commit, perhaps for a few months at first, to meeting regularly. If you're honest, and enter in, asking how can I encourage, pray and serve the other two, I'm pretty confident you'll find it immensely life-giving.
