The Battle Is the Lord’s

October 20, 2026 · Anne Barkley

SCRIPTURE FOCUS:

“Do not be afraid or be dismayed because of this great multitude, for the battle is not yours, but God’s.”

— 2 Chronicles 20:15

When circumstances seem overwhelming, God calls His people to stand firm in faith rather than surrender to fear. Through David’s victory over Goliath, Jehoshaphat’s deliverance, and the promises of Jesus Christ, Scripture reminds us that our strength comes from the Lord. We are called to pray, trust, praise, and remain steadfast, knowing that God’s power is greater than any battle we face.

The phrase “The battle is the Lord’s” appears in the Old Testament account of David’s victory over Goliath in 1 Samuel 17:47; reinforced in 2 Chronicles 20:15 where King Jehoshaphat is told the battle belongs to God; and in the New Testament in Ephesians 6:10-13 addressing spiritual warfare.

The statement expresses confidence that the ultimate outcome depends on divine power and providence, rather than merely human strength or strategy. While it certainly applies to literal battles in the Old Testament, it is a thread that moves throughout Scripture that emphasizes the Sovereignty of God and His ability to rule and overrule in every area of life.

In times like these, we are witnessing a multitude of both physical and spiritual battles, and we can become overwhelmed with stress or give in to fear because fear is a liar. We must not give in to what we see!

God is in total control and is delivering His children and nations. He is judging our enemies, changing things and returning what has been stolen. God is the same yesterday, today and forever and He is still on the Throne.

We must rely, trust, and focus on God. The battle is the Lord’s, and the battle has been won! God is working things out and moving in our lives one step at a time.

As believers we must keep our focus on God, and we will see victory both in our personal lives and in our nation!

David’s Claim That “The Battle Is the Lord’s:”

The adversaries of Israel were the Philistines (1 Samuel 17:1-3) and, more specifically, Goliath a giant, measuring about 9 feet tall and fully girded with armor.

The conflict climaxed after 40 days with Goliath appearing before the army of Israel and challenging them to a one-on-one duel that would result in the defeat of the opposing army. (17:4-7)

This challenge resulted in fear for the people of Israel (17:11)—all except for David.

It is important for us to examine the background of how David was prepared to rise to battle a giant.

David asks the right question, “Who is this uncircumcised Philistine that he should defy the armies of the living God?” (17:26)

David was familiar with the law to Israel through Moses found in Deuteronomy 20 that begins with a foundational principle for warfare—the God who delivered Israel from one of the most powerful nations in the known world, Egypt, was with them.

He was the source of their strength, and just as He miraculously delivered Israel from the hands of Egypt, He could and would continue to deliver them from the hands of their adversaries.

David stood upon the promises and faithfulness of God in taking his stand against Goliath.

David was a sheepherder, the youngest of his family and a non-participant in battle. David was only present on the battlefield because he had delivered food to his three oldest brothers.

Upon arriving, David had realized what was taking place—Israel was standing in fear of an opposing army.

David volunteered to be the one to fight Goliath—a young sheepherder against a giant warrior. If David were to lose the battle, all of Israel would become servants of the Philistines.

David argued his case, relating his success in fighting both a lion and a bear. David did not mention his own strength against these animals but instead pointed to God’s power that would result in Goliath being defeated like the lion and the bear.

David had faith that God would defeat Goliath, and that he would be successful in battle.

David did not fear the verbal assaults of Goliath but declared;

“You are coming to me with a sword, a spear and a javelin, but I am coming to you in the Name of the LORD of hosts, God of the armies of Israel, whom you have defied.

This very day the LORD will deliver you into my hand, and I will strike you down and take your head off you, and I will give the carcasses of the Philistines’ camp today to the birds of the sky and the wild beast of the earth.

Then all the earth will know that there is a God in Israel, and so all this assembly will know that the LORD delivers not with sword and spear—for the battle belongs to the LORD—and He will give you into our hands.” (I Samuel 17:45-47)

David prevailed over the giant with a sling and a stone, struck the Philistine down and killed him. (17:50)

God used the physically weakest of the family of Jesse to display His might before the world. God maintains this pattern of utilizing the weak to shame the strong of the world, displaying His might and bringing Himself glory.

“The Battle Is God’s” Spoken to Jehoshaphat:

In the days of King Jehoshaphat, fourth king of Judah, the Moabites and Ammonites (descendants of Lot) came together to make war against him. (2 Chronicles 20:1-2)

He was afraid and he prayed to the LORD and proclaimed a fast throughout all Judah and all the people came together.

Jehoshaphat stood in the congregation of Judah and Jerusalem in the House of the LORD and said;

“LORD God of our fathers, are You not God in heaven. You rule over all the kingdoms of the nations. Power and might are in Your hand and no one can stand against You…

If calamity comes upon us—the sword of judgment, pestilence or famine—we will stand before this House and before You—for Your Name is in this House—and cry to You in our distress and You will hear and deliver us.” (2 Chron. 20:5-9)

Then, Jehoshaphat pleaded for God’s judgment upon their enemies;

“Our God, will You not execute judgment upon them? For we have no power to face this great multitude that is attacking us. We do not know what to do—but our eyes are on You.” (v. 12)

God’s Spirit came upon Jahaziel and spoke these words,

“Thus the LORD says to you, ‘Do not be afraid or be dismayed because of this great multitude, for the battle is not yours, but God’s…

You will not fight in this battle. Take your positions, stand and see the salvation of the LORD with you, O Judah and Jerusalem.

Do not be afraid or be dismayed. Tomorrow, go out to face them, for the LORD is with you.” (vv. 15-17)

Jehoshaphat and the people responded by bowing down in worship and praise to the God of Israel with a very loud voice.

Jehoshaphat spoke to the people and said, “Believe in the LORD your God and you will be confirmed. Trust in His prophets and you will succeed.” (v. 20)

He appointed singers to praise the LORD for the splendor of His holiness as they went out before the army saying, “Praise the LORD, for His mercy endures forever.” (v. 21)

As they sang praises, the LORD set ambushes against the enemies who came against Judah and they were defeated. (v. 22)

The principle remains consistent: humans commonly face overwhelming odds, but God’s power is unconstrained by human limitations. Time and again, when Israel seeks the LORD, miraculous deliverance follows.

From Genesis through Revelation, God consistently intervenes on behalf of His people-whether it is delivering Israel from Egyptian bondage, guiding them in the wilderness, or ultimately providing salvation through the resurrection of Christ.

Each account underscores the same truth: human frailty depends wholly on divine rescue.

New Testament Affirmation of the “Battle Is the Lord’s”:

Though the exact phrase “The battle is the Lord’s” is drawn from the Old Testament, the New Testament echoes this theme in the person of Jesus Christ.

It was the angel who spoke to Mary concerning the birth of Jesus, “For nothing will be impossible with God.” (Luke 1:37)

Jesus in John 16:33 reminded believers: “In the world you will have tribulation. But take courage; I have overcome the world.”

The apostles frequently drew from Old Testament principles, teaching that human strength falters but God’s power remains triumphant.

In Romans 8, Paul proclaims that believers are more than conquerors through Christ and reminds us that nothing in creation, including death or spiritual powers, can separate believers from the love of God in Christ Jesus.

Philippians 4 encourages faith and obedience and invites believers to cast our anxieties on God through prayer and know that: “We can do all things through Christ who gives us strength.”

Paul assures us that the Lord is faithful and will strengthen and guard us from the evil one. (2 Thess. 3:3)

We are to daily put on the spiritual armor of God to protect us against spiritual adversaries.

The promise is not immunity from suffering, but the presence of God through it, ensuring that no enemy has the final word and that His purposes prevail.

John in Revelation 3:10 promises to keep faithful believers safe from the coming hour of trial on the earth.

Practical Application:

1. Confidence in Spiritual Warfare.

Many teachings in the New Testament about resisting the devil (James 4:7-8) and standing firm in faith (1 Peter 5:8-9) echo the principle that God fights for and with His people.

Believers today, facing physical and spiritual challenges, can adopt David’s and Jehoshaphat’s perspective, relying on divine strength rather than human effort.

2. Guidance in Personal Struggles.

Whether the conflict is relational, emotional, or related to life decisions, turning first to prayer and Scripture reflects the belief that ultimate resolution rests in higher hands.

This viewpoint nurtures an attitude of humility, perseverance, and peace and reflects praise and worship to God.

3. Encouragement and Trust.

When circumstances appear daunting, recognizing that “The battle is the Lord’s” moves hearts to faith instead of fear.

It prompts humble dependence on God’s power and a relinquishing of personal attempts to control each situation.

This posture of trust invites miracles and divine breakthroughs.

In the days of Jehoshaphat, God spoke through a prophet to give direction and courage.

God is still speaking through prophets today as many things are about to look much different—governments, nations, economies, and the church.

God is bringing much change as He moves His hand across this Nation and the nations of the world.

He is speaking through His prophets to His people today:
