Why Does God Allow Wars?

FROM ANCIENT times until today, war has left deep scars on humanity. Families shattered, cities destroyed, and millions of lives lost—all these raise a painful but necessary question: Why does God allow wars? If He is all-powerful and all-loving, why not stop the bloodshed?

What Causes War?

The Bible reveals the true origin of war—not merely politics, territory, or ideology, but the human heart. James 4:1-2 provides a blunt diagnosis:

“Where do wars and fights come from among you? Do they not come from your desires for pleasure that war in your members? You lust and do not have. You murder and covet and cannot obtain. You fight and war.”

According to Scripture, war is the external expression of internal conflict—a product of lust, greed, pride, and selfish ambition. The vanity of nations mirrors the vanity of individuals, driven by desires for power, resources, dominance, or revenge. Whether among tribes or modern superpowers, the root cause remains unchanged.

Wars in the Bible

The Bible does not shy away from the reality of war. The first recorded fight was between brothers Cain and Abel (Genesis 4). In fact, many wars are recorded—from Abraham rescuing Lot, to the Israelites conquering Canaan, to David’s military campaigns. Yet, these were not mere human endeavors; often, they involved God’s direct judgment or intervention.

Sometimes God allowed wars as a form of punishment or to fulfill His plan and prophecy. For example, God used Assyria and Babylon to punish Israel and Judah for their sins (Isaiah 10:5-6; Jeremiah 25:8-9). Yet even in this, He always had a purpose: to bring repentance and ultimately restoration.

The Toll of Human Suffering

War brings deep suffering—death, disease, famine, and broken families. Some ask: Why would a loving God allow such pain?

The hard truth is that mankind has rejected God’s way of peace. From the Garden of Eden, humanity chose to determine right and wrong for itself, apart from God's commandments. As a result, we now live in a world reaping the consequences of that choice.

God allows suffering and war not because He delights in it, but because He is allowing humanity to learn that our ways do not work. He could stop every war, every dictator, every missile—but then, would we learn? Would we truly change?

Learning Lessons the Hard Way

Just as a parent sometimes allows a child to suffer the consequences of disobedience so they learn and grow, God allows humanity to face the results of its actions. Ecclesiastes 7:14 tells us:

“In the day of prosperity be joyful, but in the day of adversity consider: Surely God has appointed the one as well as the other…”

It is in times of trial that many turn to God in humility. War shocks people out of complacency. It reveals how fragile human civilization truly is and how deeply we need God’s intervention.

What Should We Do During War?

As believers, we must not fear. Psalm 46:1 reminds us, “God is our refuge and strength, a very present help in trouble.” Our duty is to:

As believers, we must not fear. Psalm 46:1 reminds us, “God is our refuge and strength, a very present help in trouble.”

Our duty is to:

◾️Trust in God, not in weapons or governments.

◾️Pray for protection and peace (1 Timothy 2:1-2).

◾️Live righteously, so we may be counted worthy to escape future judgment (Luke 21:36).

◾️Help others—emotionally, physically, and spiritually—as God’s representatives on Earth.

We are not called to panic, but to shine as lights in dark times (Philippians 2:15).

Hope in the Scriptures

God has not abandoned the world. Scripture promises that a time will come when wars will cease, not by human peace treaties, but by the establishment of the Kingdom of God.

Isaiah 2:4 says:

“He shall judge between the nations, and rebuke many people; they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war anymore.”

Micah 4:1-3 echoes the same promise. This peace will only come when Christ returns to establish His reign over the Earth. Only then will the hearts of men be changed, and the causes of war—lust, pride, greed—be removed.

To Form A Perfect Character

Even in times of war, God is working out a purpose. Romans 5:3-4 reminds us:

“Tribulation produces perseverance; and perseverance, character; and character, hope.”

War is never God's ultimate will, but in allowing it, He is shaping hearts, testing faith, and preparing a people for His Kingdom. Those who endure trials faithfully are being refined like gold (1 Peter 1:6-7).

The End of War Is Coming

While wars rage today, the Bible assures us they will not last forever. Christ will return—not as a lamb, but as the Lion of Judah, to bring judgment and peace. Revelation 19 shows Him leading the armies of heaven, not to destroy the world, but to save it from self-destruction.

Jesus Christ assured everyone,

"...And unless those days were shortened, no flesh would be saved; but for the elect’s sake those days will be shortened." (Matthew 24:22)

Until then, let us live by faith, prepare spiritually, and hold fast to the hope that soon, “they shall not learn war anymore.” (Micah 4:1-3)
