Overview
Joshua is the book of inheritance — the account of God's people finally entering and taking possession of the land He had promised to Abraham four centuries earlier. After the long years of Egyptian slavery, the Exodus, the covenant at Sinai and forty years of wilderness wandering, Israel crosses the Jordan and begins to receive what God had pledged.
The book follows Joshua, Moses' successor, as he leads Israel across the Jordan, conquers the strategic city of Jericho, campaigns through the land and oversees its division among the twelve tribes. It is a book of battles — real, costly, sometimes bewildering — but also a book of extraordinary faith. The walls of Jericho fall not to military tactics but to obedience and trust.
Joshua ends with a covenant renewal ceremony at Shechem. The land has been given. The faithfulness of God has been demonstrated. Joshua's final charge to the people is both urgent and simple: "Choose this day whom you will serve."
When Written and By Whom
The book is named for its central figure, Joshua son of Nun, and tradition holds that Joshua himself wrote much of it, with some later additions by the priests or a successor after his death. The events described took place following the forty years of wilderness wandering, beginning around 1405 BC.
Joshua was ideally placed to record these events — he had been Moses' aide since the Exodus, was present at Sinai, led Israel across the Jordan and commanded the campaigns of conquest. The book bears the marks of eyewitness familiarity with the events it describes.
Links to Jesus
The connection between Joshua and Jesus begins with the names themselves — "Joshua" and "Jesus" are the same name, the Hebrew Yeshua meaning "the Lord saves." This is not incidental. It is a deliberate echo that the New Testament authors were well aware of.
Joshua leads Israel into the Promised Land — into rest, into inheritance, into the fulfilment of God's promise. But the letter to the Hebrews is explicit that Joshua's rest was not the final rest: "If Joshua had given them rest, God would not have spoken of another day later on" (Hebrews 4:8). The true rest that remains for the people of God is found in Christ, who leads His people not into a geographical territory but into a lasting, eternal inheritance.
Rahab the prostitute, who sheltered the Israelite spies and was saved when Jericho fell because of a scarlet cord in her window, is named in the genealogy of Jesus in Matthew 1. Her faith — trusting the God of Israel on the basis of what she had heard — is held up in Hebrews 11 as a model of genuine faith. She is a picture of the Gentile who is brought in through faith and sheltered by the grace of God.
The crossing of the Jordan on dry ground echoes the crossing of the Red Sea and anticipates baptism — passing through water into new life and new territory under God's leading.
Key Verses
"Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go." — Joshua 1:9
"As for me and my house, we will serve the Lord." — Joshua 24:15
"Not one word of all the good promises that the Lord had made to the house of Israel had failed; all came to pass." — Joshua 21:45
Main Theme
God keeps His promises — fully, faithfully and on His own timetable.
The land promised to Abraham was not received immediately. It came after centuries, through slavery, wilderness and warfare. But it came. Joshua 21:45 is the quiet, decisive verdict on the whole story: "Not one word of all the good promises that the Lord had made to the house of Israel had failed." That single verse is one of the most reassuring in all of Scripture.
Impact for Today
Joshua 1:9 has sustained believers in every generation: "Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go." These words were not given to someone in comfortable circumstances — they were given to a man about to lead a nation into hostile territory, under the weight of following an extraordinary leader. The command to courage and the promise of presence belong together.
The book also confronts comfortable assumptions about how God works. The battles of Canaan trouble many readers, and honestly so. They are not easy to read. But they are part of a larger story of a God who takes sin seriously, who acts in history and who is not tame or distant. Wrestling with the difficulties of Joshua is itself part of taking the Bible seriously.
Joshua's final challenge — "Choose this day whom you will serve" — remains the question every generation must answer. There is no middle ground in Joshua, just as there is none in the Gospel. The land is given, the faithfulness of God is demonstrated, and the people must decide whether they will walk in it.
For the believer today, Joshua points forward: we too are being led into an inheritance. The One whose name echoes Joshua's is bringing His people through and into rest. He will not lose a single one along the way.
