Understanding Joshua 1:6-9 in Depth: Be Strong and Courageous

A New Leader for a New Chapter

With Moses gone, God calls Joshua to lead Israel forward into the land He promised long ago.

This moment follows immediately after the death of Moses, Israel’s great deliverer and lawgiver, who led them out of Egypt and through the wilderness but was not permitted to enter the Promised Land himself. Now, Joshua, who had served faithfully as Moses’ assistant, is commissioned by God to take the people across the Jordan and into Canaan. The transition marks a turning point in leadership and in Israel’s entire journey from wandering to inheritance. God’s words to Joshua echo His earlier promises to Abraham in Genesis 12:7, where He said, “To your offspring I will give this land,” and reaffirm the boundaries described in Genesis 15:18-21.

God tells Joshua to be strong and courageous three times in these verses - not because the task is easy, but because it will require deep trust. He must lead a nation of millions into unfamiliar territory, facing fortified cities and powerful enemies, yet God’s command is clear: do not turn from the law Moses gave, because obedience is the path to success. This isn’t about military strategy alone. It’s about staying rooted in God’s instructions, which is why Joshua is told to meditate on the Book of the Law day and night. The same promise given to Moses in Deuteronomy 31:7-8 - that God would go with him and never forsake him - is now passed to Joshua.

The repeated command to “be strong and courageous” applies beyond Joshua’s moment; it is a pattern God uses with those He sends. Courage here comes not from confidence in self but from certainty in God’s presence, as He said to Moses and later to Israel. And that same presence is what makes all the difference when facing the unknown.

This divine assurance sets the tone for everything that follows in Joshua’s leadership, preparing us to see how faith and obedience open the way for God’s promises to become reality.

The Heart of God's Commission to Joshua

God’s commission to Joshua is about more than bravery; it is about identity, obedience, and staying rooted in His Word.

The command to 'be strong and courageous' appears three times in this short passage (Joshua 1:6, 7, 9), showing how deeply fear could take root when facing giants and new territory. This wasn’t empty encouragement. It was a call to align courage with covenant. Moses was told in Deuteronomy 31:6, "Be strong and courageous." Do not fear or be in dread,' so now Joshua inherits that same promise. Courage here isn’t about boldness in battle, but trust in God’s faithfulness to His promises.

When God says, 'Do not turn from it to the right hand or to the left,' He’s using a phrase also found in Deuteronomy 5:32 and 28:14, where it means staying completely faithful to His commands. In ancient Near Eastern culture, going 'right or left' of a path meant breaking from an agreed-upon covenant, like a vassal king disobeying his suzerain. For Joshua, obedience isn’t optional - it’s the very condition for success. And 'success' here isn’t measured by wealth or power, but by walking in God’s will. The Book of the Law should be on his lips constantly; it must be read and meditated on day and night, like a warrior rehearsing his mission or a student memorizing truth.

Meditating on God’s Word ‘day and night’ isn’t about endless study sessions. It means letting Scripture shape how you think, decide, and lead. In a world where kings relied on advisors and omens, God tells Joshua his true guide is the Law. This mirrors Psalm 1:2, which says the blessed person 'meditates on the law of the Lord day and night,' showing this practice leads to spiritual prosperity. Joshua’s leadership isn’t built on charisma or strategy, but on daily surrender to God’s voice. The presence of God - "I will be with you wherever you go" - is the foundation, not merely a comfort. That promise echoes through time, like when Jesus assures His disciples in Matthew 28:20, 'I am with you always,' showing divine presence is central to every mission God gives.

This Book of the Law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it.

This passage sets a pattern for all who follow God into uncertain futures: strength comes not from self, but from staying close to Him through His Word. As we move forward, we’ll see how Joshua’s obedience opens the way for miracles, starting with the crossing of the Jordan.

Courage Rooted in Covenant and Presence

Joshua’s calling shows us that true leadership in God’s kingdom isn’t about skill or status, but about faithfulness to His covenant and confidence in His presence.

In ancient times, a new king or leader was expected to prove himself by making alliances, building armies, or seeking omens - but God tells Joshua his strength comes from something entirely different: obedience to the Law and constant remembrance of God’s promises. This reflects the covenant loyalty Israel was meant to live by, where staying faithful to God’s commands was the path to life and blessing, not political strategy. Just as Moses was told in Deuteronomy 31:6, 'Be strong and courageous. Do not fear or be in dread,' so Joshua is reminded that fear has no place when God is with you.

The promise 'the Lord your God is with you wherever you go' echoes across the Bible, showing God’s unchanging faithfulness - not only to Joshua, but to all who follow Him.

Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go.

While this isn’t a direct prophecy about Jesus, it points forward to how Christ fulfills this role perfectly: He is the ultimate leader who obeys the Father completely and promises His followers, 'I am with you always, to the end of the age' (Matthew 28:20). This passage isn’t about ancient history; it is a call for every believer to lead and live with courage, grounded in God’s Word and His ever-present help.

A Promise Fulfilled and a Presence Foretold

This moment with Joshua is more than a passing of the torch; it is a pivotal step in God’s long story of promise, presence, and ultimate redemption.

From Abraham in Genesis 12, God pledged a land, a people, and a blessing. Now, under Joshua, that promise begins to take physical shape. Moses led Israel out of Egypt, but Joshua leads them into the inheritance - fulfilling what God swore centuries earlier. This is the unfolding of covenant faithfulness, where God’s word across generations finally meets its moment of realization.

Yet this passage also points beyond Joshua to someone greater. Joshua was called to meditate on God’s Word day and night. Jesus, the Word made flesh, perfectly obeyed the Father in every thought and action, fulfilling the law completely, as Hebrews 10:5-9 declares: "You have prepared for me a body..." I have come to do your will, O God.' While Joshua led Israel into a land of milk and honey, Jesus leads us into eternal life, not merely across the Jordan but through death and resurrection. God promised Joshua, "I will be with you," and Matthew 1:23 reveals Jesus as Immanuel - "God with us" - fulfilling that promise in the most personal way possible.

Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go.

The courage God commands Joshua to have is not mere bravado, but trust in God’s presence - a theme Paul picks up centuries later when he tells Timothy, 'For God gave us a spirit not of fear but of power and love and self-control' (2 Timothy 1:7). Joshua’s strength was rooted in obedience and the nearness of God. Ours is rooted in Christ, who has already overcome fear, sin, and death. As we follow Him, we see that every command to be strong and courageous finds its answer not in our effort but in His presence - leading us forward, as it led Joshua.
