Joshua opens at a hinge moment. Moses is dead. The wilderness generation is buried in the sand behind them, and the Jordan is in front of them. The new commander has spent forty years as a second — assistant to Moses, one of two faithful spies — and now the weight falls on him alone. The text is written for a people who must cross a river into a land already occupied by entrenched kings and other gods. The threefold command to be strong and courageous is not a pep talk; it is an inauguration. The grounding is not Joshua's competence but the presence of the LORD.

From the writers we read together

C.S. Lewis

Oxford literary scholar, Anglican lay theologian (1898-1963)

Lewis' line is exactly the one Joshua 1 needs. Joshua already knows the law; he has watched Moses for forty years. What he is being commanded now is not new information but the courage to act on what he already believes when the river is high and the cities are walled. Lewis saw that every virtue — honesty, kindness, chastity, faith — eventually arrives at a moment where holding it costs something, and at that moment the virtue either becomes courageous or it evaporates. Meditation on the Book of the Law (v. 8) is not separate from courage (v. 9); it is the fuel that makes courage possible when the testing point comes.

Notice that the Lord does not promise Joshua an easy crossing. He promises presence: the LORD your God is with you wherever you go. Lewis would say this is the only ground on which courage can finally stand. Bravery rooted in self-confidence breaks at the first wall. Bravery rooted in the company of a God who has already crossed every river ahead of you is something else. Whatever you are walking into today — a conversation, a diagnosis, a decision you have been postponing — the command is not feel brave. The command is go, because he goes with you.
