What does "be strong" teach on courage?
What does "be strong and let us fight bravely" teach about Christian courage?

Context Surrounding “Be Strong and Let Us Fight Bravely”

• The words are spoken by Joab, commander of David’s army, when Israel faces a combined force of Ammonites and Arameans (2 Samuel 10:12).

• Israel’s soldiers are outnumbered, yet Joab rallies them with a God-centered charge:

“Be strong and let us fight bravely for our people and the cities of our God. May the LORD do what is good in His sight.”

• The phrase is echoed later by Joab’s brother Abishai in the parallel account (1 Chronicles 19:13). These are not mere motivational slogans; they are faith-filled orders anchored in trust that God controls the outcome.


The Call to “Be Strong”

• “Be strong” translates a Hebrew verb that means to fasten oneself, to seize with courage, to take hold of firm resolve.

• Strength here is moral and spiritual before it is physical. It is the settled conviction that God’s promises are certain and His presence is sufficient.

• Scripture consistently roots strength in the Lord, not in personal grit:

• “Be strong and courageous… for the LORD your God is with you wherever you go.” (Joshua 1:9)

• “Be strong in the Lord and in His mighty power.” (Ephesians 6:10)


The Charge to “Fight Bravely”

• Courage is not passive. Joab expects disciplined action that flows from faith.

• Biblical bravery pursues righteousness even when odds appear overwhelming.

• Joab states their aim: “for our people and the cities of our God.” The fight is for God’s purposes, God’s reputation, and the well-being of God’s covenant people.

• True bravery refuses self-glory; it surrenders the final result: “May the LORD do what is good in His sight.”


Where Christian Courage Finds Its Source

• Confidence in God’s sovereignty—He will “do what is good.”

• Commitment to God’s mission—protecting “the cities of our God.”

• Community focus—“for our people.” Biblical courage is others-centered, not self-preserving.

• Consistent walk—believers cultivate courage daily, so it is ready in crisis (Psalm 27:1; 1 Corinthians 16:13).


Living Out This Courage Today

• Stand firm for biblical truth when culture pressures compromise.

• Defend the vulnerable in church, family, and society.

• Persevere through personal trials with unshaken trust that God governs outcomes.

• Engage spiritual warfare in prayer, Scripture, and obedience, “putting on the full armor of God” (Ephesians 6:11-18).


Key Reinforcing Scriptures

Deuteronomy 31:6 – “Be strong and courageous… the LORD your God goes with you.”

Psalm 31:24 – “Be strong and let your heart take courage, all you who hope in the LORD.”

1 Corinthians 16:13 – “Be on the alert. Stand firm in the faith. Be men of courage. Be strong.”

2 Timothy 1:7 – “For God has not given us a spirit of fear, but of power, love, and self-control.”

Courage, then, is faith-fueled action that steps forward for God’s glory and the good of His people, leaving the results in His sovereign hands—exactly what Joab’s rally cry models: “Be strong and let us fight bravely.”

How does 2 Samuel 10:12 encourage us to trust in God's sovereignty today?
