In recent years, neuroscience has opened some previously locked doors into our understanding of the brain. As a Christian, I love to learn what I can from scientists who are studying God’s world and how He designed it. I don’t put research in the same authoritative category as revelation, but it’s still incredible to discover how often science and Scripture dovetail so well. Scripture often points out how the natural world directly confronts us with the glory and grandeur of God (Psalm 19:1-4; Romans 1:18-23).

One clear area where I’ve seen this is in the area of neuroplasticity. Norman Doidge, a psychiatrist and researcher says, “Neuroplasticity is the property of the brain that allows it to change its structure and function in response to what it senses, what it does and even what it thinks and imagines.”

Let me break that down. Pictures of the brain now indicate that by introducing new thoughts, attitudes, and habits of the mind, you can actually change the structure of your brain. The reason this fascinates me is that Scripture speaks not about the brain per se, but about being “transformed by the renewal of your mind” (Romans 12:2). We also read about “taking every thought captive” (2 Corinthians 10:4) as a central aspect of spiritual warfare. 

All of this leads me to think about Bible memorization and why I believe it’s likely the most powerful spiritual discipline for transformation—especially as it is linked with meditation on Scripture. Here’s why: What we think about determines how we will act. If our words and actions are the fruit, then what has captured our mind is the root of all spiritual growth. In large part, our thoughts determine the outcome of our life.

I want to give ten reasons why developing a habit of memorizing Scripture might just change your life (I know it has mine!). But one quick note of caution: Memorizing Scripture should not be thought of as a do-it-yourself hack for spiritual growth. Like all areas of growth in the Christian life, it should be done with prayerful dependence on the Holy Spirit. You can sow and water, but only God gives the growth.

10 Reasons to Memorize Scripture

1. Jesus did it. It’s clear from passages like His battle with the devil in the desert that Jesus had spent years saturating His mind in Scripture, because He’s able to deftly counter each of Satan’s temptations with the sword of God’s Word from memory (Matthew 4:1-11). If it’s good enough for the Son of God, it’s good enough for me.
2. It leads to prosperity and success, as God defines them. Joshua was commanded to meditate on the Word of God over and over, day and night (Joshua 1:8; cf. Psalm 1:1-3). Scripture memorization is all about thinking over a truth until you can speak it from your heart. God promises spiritual victory, blessing, and success if you will commit to this practice diligently.
3. It renews your mind. As mentioned above, we often carry many lies in our minds connected to our past (I’m worthless; I’m disgusting; No one cares about me; God doesn’t love me), and we need to wash out the lies with repeated exposure to God’s Word. Memorizing Scripture trains our minds to think differently about God, ourselves, and our purpose.
4. It’s a weapon against temptation. Psalm 119:11 gives it to us straight: “I have stored up Your word in my heart, that I might not sin against You.” Memorizing Scripture has a purifying power that guards our thoughts. When you’re up against temptation, you’ll find yourself standing less on your emotions and more on the rock-solid truth of Scripture.
5. It provides you with wisdom. As you memorize Scripture, you are thinking about a truth over and over. As you meditate on a principle, it develops wise thinking for all areas of life, and new neural pathways are carved out in your gray matter. “Your commandment makes me wiser than my enemies… I have more understanding than all my teachers, for your testimonies are my meditation” (Psalm 119:98-100). Scripture is a lamp to your feet and a light to your path (Psalm 119:105). So, the more you memorize, the more light you carry with you in this dark world.
6. It motivates you for ministry. Just as 2 Timothy 3:16-17 says, all of Scripture is profitable “that the servant of God may be complete, equipped for every good work.” When you have memorized a truth, it begins to work its way into your psyche and compels you to live out its truth. You will want to help others know and follow Jesus because of it.
7. It empowers your prayer, worship, and intimacy with God. As you marinate your mind with God’s words, you are given new words of prayer and affection for God. In John 15:7, Jesus said, “If you abide in Me, and My words abide in you, ask whatever you wish, and it will be done for you.”
8. It strengthens you for spiritual warfare. Demonic attacks often come in the form of deception—which is easy to drift into when you’re not attuned to the truth. As you meditate and memorize Scripture, you arm yourself for the battle so you can “destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ” (2 Corinthians 10:5).
9. It liberates you from habitual sins. When Christian brothers tell me that they have been ensnared by a particular sin they know is wrong and just want to be free from, I always encourage them to memorize Scripture that directly targets the sin they are battling. The truth sets us free, Jesus said. Psalm 119:9 adds: “How can a young man keep his way pure? By guarding it according to your word.” John Bunyan once said it so well: “Either this book will keep you from sin, or sin will keep you from this book.”
10. It will give you greater joy in Jesus. Psalm 119 constantly speaks about how God’s Word is the delight of those who know and follow His precepts. Because memorizing Scripture transforms your affections, you find new delight in knowing God’s will for your life and not being defeated by sin and deception (Psalm 119:14, 16, 24, 50, 92, 111). Like Jesus, you will delight yourself in the Lord, and He will give you the desires of your heart.

Brain science tells us that new habits and experiences can change both the structure of your brain and your mode of thinking. Scripture agrees that renewal of your mind is possible. You can change old, sinful, diabolical thought patterns by replacing them with the living and active truth of God’s Word. And a major way to do this is through Spirit-empowered memorization of Scripture. I encourage you to invest time and energy into this fruit-bearing practice.
