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.
