Joshua study notes

Important Concepts

• The Kept Promise: Joshua exists to prove that God does what He says. The land sworn to Abraham is given in full, and the book’s refrain — “not one word has failed” — anchors the believer’s confidence in every promise of God, fulfilled ultimately in Christ (2 Corinthians 1:20).
• Holy War and the Justice of God: The conquest was God’s judgment on Canaanite wickedness, long delayed until their sin was “complete” (Genesis 15:16). The cherem was not cruelty but justice and a guard against idolatry, and it points to the God who will finally judge all evil.
• Salvation Belongs to the LORD: Israel receives the land; it does not achieve it. Every victory is God’s gift, teaching that His people live by grace and trust, not by their own strength.
• The Faith of Rahab: A pagan prostitute is saved by believing the reports of the LORD and acting on that faith. She becomes a standing witness that God welcomes outsiders who trust Him, and that faith, not birth, brings a person into His people (Hebrews 11:31).
• The Sin of Achan: One man’s hidden greed brings defeat on the whole nation, showing that sin is never merely private and cannot be concealed from God. Grace to Rahab and judgment on Achan stand side by side as warnings and comfort.
• Rest and Inheritance: The land is Israel’s rest and inheritance, a gift that pictures the greater rest and inheritance believers have in Christ, entered by faith and kept secure by God.

Practical Application

Joshua calls the believer to a courage rooted not in circumstances or self but in the presence and promises of God. “Be strong and courageous” is never a summons to grit one’s teeth alone; it is always joined to “for the LORD your God is with you.” The Christian faces the unknown — new callings, hard obediences, unfamiliar ground — the same way Joshua did: by meditating on God’s word until it shapes action, and by trusting the God who has never yet failed a single promise. The memorial stones remind us to remember and rehearse what God has done, so that our children and our own hearts learn to fear and trust Him.

The book also presses the danger of compromise. Israel’s later troubles trace back to the Canaanites they failed to drive out; small tolerances of sin become lifelong snares. And so the closing chapters ring with a choice that every generation must make afresh: no one drifts into wholehearted devotion. “Choose this day whom you will serve” confronts us with the reality that the LORD will share His people’s loyalty with no idol. To follow Him is a deliberate, daily, household decision to serve Him and no other.

Questions for reflection

1. Joshua’s courage rests on God’s presence and word, not his own ability. Where is God calling you to “be strong and courageous,” and how does His promise to be with you change the way you face it?
2. Rahab is saved by faith while Achan is judged for sin, though one is a Canaanite and the other an Israelite. What does this teach about who truly belongs to God, and how it points to the gospel?
3. The book insists that “not one word has failed” of all God’s promises. How does the faithfulness of God in Joshua strengthen your trust in the promises He has made to you in Christ?
