What does the Bible say about War?

The Bible has a lot to say about war. In fact, the Hebrew word for “war” appears more than 250 times in the Old Testament alone. While there is no one clear answer as to what the Bible says about war, there are certainly some principles that can be gleaned from Scripture. Here are four things that the Bible says about war.

War is a reality of this world according to Scripture.

The Bible doesn’t shy away from the harsh realities of war. In fact, it acknowledges that war is an unfortunate but necessary part of life in a fallen world. The book of Ecclesiastes even goes so far as to say that “there is nothing new under the sun” when it comes to war (Ecclesiastes 1:9).

Biblically speaking, war is often a result of human sin.

The Bible also makes it clear that war is often the result of human sin. In the book of James, we read that “where there is envy and self-seeking, there will be conflict and every evil practice” (James 4:1-2). This is true not just on an individual level, but also on a national level. When countries seek their own interests above those of others, it often leads to conflict and war.

Some war can be justifiable by God’s Word.

While the Bible acknowledges that war is often a result of human sin, it also says that there can be such a thing as a just war. In the book of Exodus, God tells the Israelites that they are allowed to defend themselves against those who would do them harm (Exodus 22:2). And in the book of Romans, Paul says that it is right for the government to use force to punish those who do evil (Romans 13:4).

War can be an opportunity for God to work.

Finally, the Bible also teaches that war can be an opportunity for God to work in people’s lives. In the book of Isaiah, we read that God uses even the Babylonians – a cruel and ruthless people – to accomplish his purposes (Isaiah 10:5-6). And in the book of Revelation, we see that God will one day use even the forces of nature to defeat his enemies (Revelation 16:14).

FAQ About War in the Bible

What did Jesus Christ say about war in the New Testament?

The New Testament is actually relatively quiet on the subject of war. Jesus Christ addresses the topic in just a handful of verses, and even then, He doesn’t take a particularly strong stance for or against military conflict. That being said, the few times that Jesus does address war in the New Testament, He makes it clear that He is not a fan. In Matthew 5:9, Jesus says “Blessed are the peacemakers, for they will be called sons of God.” And in Luke 22:36, He says “If you don’t have a sword, sell your cloak and buy one.” But immediately after saying this, He adds “for I tell you that this Scripture must be fulfilled in Me.”

Biblically, can Christians fight and kill people in wars?

The Bible is clear that Christians are called to love their enemies and pray for those who persecute them. However, given the fallen nature of our world, there may be situations where self-defense or defense of others may be necessary. In those cases, Christians should always act with grace, compassion, and restraint.
Christians should never desire war or unnecessarily take lives. But in a broken world where there is evil and injustice, sometimes Christians need to fight – not just through prayer and worship but also through earthly means. If we are called to love our neighbor as ourselves (Mark 12:31), then that means defending them from harms way. Sometimes that will require violence in the form of self-defense.

How does the commandment “Do Not Murder” relate to war?

The Sixth Commandment is “Thou shalt not kill” (Exodus 20:13). To properly answer the question, we must understand what “kill” means. The word “murder” comes from the Latin word “morteri” which means “to kill.” Thus, when we murder someone, we are killing them in a way that is contrary to the Law of God. When the Government goes to war, they are not committing murder because they are acting in accordance with the lawful use of force. The rightful use of force is necessary at times to protect innocent life and defend one’s countrymen from evil aggressors.

Will there be a war in the end times according to the Bible?

There is no one definitive answer to this question. However, there are several scriptures that suggest war will be a part of the end times. For instance, in John’s Revelation, there is mention of a war between the forces of good and evil (Revelation 19:19-21). In addition, Jesus said that wars would increase before His return (Matthew 24:6-7) and Paul wrote about a time when people would be “lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy,…without natural affection” (2 Timothy 3:1-3). From these verses it seems that war and violence may become more prevalent in the end times.
