Joshua — Be Strong and Courageous

Who was Joshua?

Joshua son of Nun first appears in Scripture as the commander Moses chose to fight the Amalekites (Exodus 17:9) — a battlefield appointment that launched one of Scripture's most enduring military and spiritual careers. He served as Moses' personal attendant from youth (Numbers 11:28), which placed him in proximity to the most significant prophetic voice of his generation. When Moses went up the mountain to receive the law, Joshua went with him as far as permitted. When Moses entered the tabernacle to speak with God, Joshua remained at the entrance, apparently unwilling to leave even after Moses departed (Exodus 33:11).

This early detail about Joshua — staying at the tabernacle when Moses left — is the key to understanding him. Joshua was not primarily a military strategist, though he was effective as one. He was primarily a man of God's presence. His courage was not self-generated bravado. It was the confidence that comes from proximity to the One who never loses. The courage commanded so insistently in Joshua 1 was available to him because he had been near the source of it for forty years in the wilderness before he ever crossed the Jordan.

His name, Joshua — Yehoshua in Hebrew — means "the LORD saves" or "the LORD is salvation." It is the same name as Jesus (Yeshua in Aramaic). The New Testament writers did not miss this. Hebrews 4:8 makes the connection explicit, noting that if Joshua had given Israel the true rest, there would have been no need for God to speak of another day. Joshua brought Israel into the physical promised land; Jesus brings believers into a rest that the physical land could never fully represent. Joshua's name was a prophetic title before he knew his own calling.

The twelve spies — and the courage to stand alone

Numbers 13 records the mission that defined Joshua's generation: twelve spies sent into Canaan to assess the land. They came back with the same objective report — the land truly flows with milk and honey, and here is the fruit — but with diametrically opposed conclusions. Ten spies said the land was unconquerable: the cities were walled and great, the people were giants, and "we were in our own sight as grasshoppers, and so we were in their sight" (Numbers 13:33). The grasshopper self-assessment is one of the most psychologically precise descriptions of the paralysis that fear produces.

Caleb silenced the people and gave the minority report: "Let us go up at once, and possess it; for we are well able to overcome it" (Numbers 13:30). Joshua joined him in what became the only two votes for trust in God's word. The majority panicked. The congregation wept through the night and spoke of stoning Caleb and Joshua. God responded with one of the most severe judgments in the wilderness narrative: the entire generation that refused to trust would die in the desert without entering the land. Only Caleb and Joshua, because they "wholly followed the LORD" (Numbers 14:24), would live to see what they had believed in.

Joshua had to wait forty years for the promise made in Numbers 14. He wandered the wilderness with a nation of people who could not receive what he had been promised, watching a generation die around him, keeping the faith alive through decades of delay. The courage he demonstrated at the border of Canaan was not a sudden surge of bravery. It was forty years of sustained trust that had never given up what it saw when the rest of Israel saw only grasshoppers and giants.

God's command to Joshua — and why it had to be said four times

Moses is dead. The opening of the book of Joshua is grief and transition compressed into a few verses. "Moses my servant is dead; now therefore arise, go over this Jordan" (Joshua 1:2). God does not allow extended mourning — the narrative momentum is forward, across the river, into the land. And then, before any strategy is discussed, before any military briefing, God delivers the one thing Joshua actually needs: a command about his inner state.

"Be strong and of a good courage" — three times in nine verses. Then the tribes of Reuben, Gad, and Manasseh echo it: "Only be strong and of a good courage" (Joshua 1:18). The fourfold command is not rhetorical decoration. It is God's honest acknowledgment that what Joshua faces requires courage he does not naturally have. The cities are walled. The nations are larger and more entrenched. The predecessor was Moses. Every reason to hesitate was legitimate. God names the fear by commanding against it.

The theological architecture of the command is important. God does not say "be strong because you are capable." He says "be strong because the LORD your God is with you wherever you go." The courage is not grounded in Joshua's personal strength. It is grounded in divine presence. This distinction matters enormously: it means the command is available to anyone who has the same promise. The presence of God is the reason for courage. The absence of fear is not required. The presence of God is.

God also gave Joshua the practical strategy for sustained courage in verses 7–8: meditate on the book of the law day and night, observe to do all that is written in it. Joshua's spiritual discipline was the underpinning of his military leadership. He was not to figure out the campaign from his own wisdom. He was to stay saturated in God's word and then go where God directed. The strategy for Jericho — march and shout — would never have emerged from a military mind. It only makes sense to someone who had learned to trust divine instruction over human logic.

The courage of Joshua — and how it is available now

Joshua 1:9's command — "be strong and courageous; be not afraid, neither be thou dismayed: for the LORD thy God is with thee whithersoever thou goest" — is quoted more in Christian contexts than perhaps any other leadership verse in the Old Testament. But it is often quoted as encouragement without its theological ground: the reason courage is possible is the presence of God, not the absence of danger or the presence of personal capability.

If you are standing at the edge of a Jordan River — a transition, a calling, a season that requires you to step into an intimidating and uncertain future — the command "be strong and courageous" is addressed to you with the same weight it carried for Joshua. And the ground for it is the same: "the LORD thy God is with thee." Not your qualifications. Not your preparation. Not your comparison to whoever came before you. The divine presence is the reason for the step.

Joshua's daily meditation on the law (Joshua 1:8) is the practical key to sustained courage. He did not stay brave through willpower. He stayed oriented through the word. His leadership decisions — including the entirely counterintuitive Jericho strategy — came from a man who had made himself available to God's instruction through sustained engagement with Scripture. Courage, in Joshua's model, is downstream of intimacy with God's word.

And Joshua's final declaration at Shechem — "as for me and my house, we will serve the LORD" — reminds us that the spiritual covenant is not a crowd decision. Joshua didn't wait to see which way the assembly voted. He declared his own household's allegiance first, and invited the nation to join. You can make the same declaration today without knowing what anyone else in your life will do. The choice is yours, unilaterally, and it can be made with the same finality that Joshua brought to Shechem.
