Joshua emerges as a central figure in the conquest of Canaan, embodying a profound example of faithfulness and leadership. As the Lord commanded Moses His servant, so Moses commanded Joshua, and so Joshua did, leaving nothing undone of all that the Lord had commanded Moses. His steadfast obedience is evident in Joshua 11:15, where he is commended for his unwavering commitment to God's directives. At the end of his life, as recorded in Joshua 24:29-31, Joshua, the son of Nun and servant of the Lord, died at the age of one hundred and ten, and Israel served the Lord all the days of Joshua and the elders who outlived him, reflecting the high regard for his leadership and the faithfulness of that generation. Despite his exemplary record, Joshua's humanity is revealed in the incident with the Gibeonites in Joshua 9, where he and Israel were deceived into making a treaty without consulting God. This mistake highlights the fallibility of even the most faithful human leaders, showing that they can be misled by outward appearances and fail to seek divine guidance on significant matters. The consequences of this decision, as seen in Joshua 9:18-27, lingered for generations, demonstrating that leaders and congregations must live with the results of their errors, yet God did not disqualify Joshua for this single misstep, acknowledging his overall record of faithful accomplishments. Joshua's role as a leader is further illustrated through the miracles associated with the conquest. In Joshua 10:1-11, during the battle at Gibeon, Joshua led a sudden march from Gilgal, and the Lord routed the Amorites with a great slaughter, casting down large hailstones that killed more enemies than the Israelite swords, underscoring God's direct intervention. Additionally, in Joshua 10:12-14, Joshua spoke to the Lord, requesting the sun to stand still over Gibeon and the moon in the valley of Aijalon, and the Lord granted this extraordinary extension of daylight to ensure a complete victory over the Amorite armies, proving that He fought for Israel. Through these events, Joshua's leadership is marked by both divine support and human imperfection. His prayerful dependence on God, as seen in the miracle of the long day, shows that God hears and responds to human pleas with miraculous provision. Ultimately, as recorded in Joshua 21:43-45, the Lord fulfilled His promises through Joshua's leadership, giving Israel the land, rest, and victory over their enemies, with not a word failing of all that He had spoken. Joshua stands as a model of striving to fulfill God's commands, despite occasional failures, encouraging a persistent pursuit of obedience and trust in divine assistance.

Joshua, a faithful leader of Israel, encountered a significant challenge with the Gibeonites, a people from a large city in the future land of Benjamin, who deceived him and the Israelites to secure a covenant of peace. Despite his otherwise outstanding record of following God, Joshua and the Israelite leaders failed to seek God's counsel when making this agreement, as noted in the critical moment when they took provisions from the Gibeonites without consulting the Lord. This lapse led to the Gibeonites becoming protected slaves, bound to cut wood and carry water, though their deception was later discovered. Joshua and the Israelites expressed more frustration over the Gibeonites' trickery than their own mistake of not seeking divine guidance, acting instead on their own understanding. This incident set a regrettable precedent, turning aside God's clear command to drive out all inhabitants of Canaan. Although Joshua faithfully destroyed other cities and nations as God instructed after this event, the exception made for the Gibeonites had long-term consequences. After Joshua's death, the Israelites began to abandon their conquest, opting to enslave rather than expel the Canaanite descendants, citing Joshua's earlier decision as justification. This failure to fully obey God's command allowed evil to persist, leading to Israel's perpetual struggle with recognizing and addressing evil, a problem that began with the Gibeonites and spread over time.

The journey of the children of Israel from slavery in Egypt to the crossing of the Jordan marks a significant transition, paralleled by the conquest of the Promised Land under Joshua's leadership. This new generation, unlike their rebellious fathers who perished in the wilderness, demonstrated greater faithfulness. Joshua, the son of Nun, led them with divine authority, as seen in his death at one hundred and ten years old, buried in Timnath Serah in the mountains of Ephraim. During his lifetime and that of the elders who outlived him, Israel served the Lord, reflecting a commendable devotion as recorded in Joshua 24:29-31 and Judges 2:7-10. Joshua, full of the spirit of wisdom as Moses had laid hands on him, was God's chosen leader, a type of Jesus Christ, sharing even the same name. The Lord spoke directly to Joshua after Moses' death, commanding him to lead the people across the Jordan into the land promised to their fathers, assuring him of His presence and success as long as he remained strong, courageous, and obedient to the law (Joshua 1:1-9). Joshua's unwavering commitment is evident in Joshua 11:15, where he left nothing undone of all that the Lord had commanded Moses. Under Joshua's guidance, the Israelites experienced miraculous events that underscored God's power and support in their conquest. The crossing of the Jordan River, at the height of its flood, was a pivotal moment where the waters stood still, allowing the people to cross on dry ground as the priests bore the ark of the covenant (Joshua 3:1-6, 14-17). This miracle exalted Joshua in the sight of Israel, assured them of God's presence to drive out their enemies, witnessed His might to the world, and taught them to fear the Lord forever (Joshua 3:7-10, 4:14, 21-24). Another significant event was the fall of Jericho, where obedience to God's instructions led to the walls collapsing after the Israelites marched around the city, blew trumpets, and shouted on the seventh day (Joshua 6:12-21). This miracle emphasized the importance of following God's commands precisely, trusting Him to fight their battles, and avoiding the cursed things of the world, which were devoted to destruction, to prevent contamination within the community. Though the conquest under Joshua was incomplete, this generation fared far better than their predecessors. Joshua's leadership, marked by strength, courage, and adherence to God's law, mirrors the greater leadership of Jesus Christ, guiding His people through their spiritual journey toward the Kingdom of God.
