Should Christians Join The Military?

Whether Christians should serve in the military has been debated for centuries. It's a complex issue that requires careful consideration of biblical teachings, historical context, and personal convictions. I've grappled with this question as a Christian who has served in the armed forces for over two decades.

The Bible contains examples of soldiers commended for their faith, such as the centurion whose servant Jesus healed (Matthew 8:5-13) and Cornelius, a centurion described as devout and God-fearing (Acts 10:1-2). However, the Bible also emphasizes principles like loving one's enemies (Matthew 5:44) and turning the other cheek (Matthew 5:39), which some interpret as incompatible with military service.

Examples of Soldiers in the Bible

The Bible mentions several soldiers in a positive light:

  • The centurion who demonstrated great faith (Luke 7:1-10)
  • The soldiers who came to John the Baptist asking what they should do (Luke 3:14)

These examples suggest that military service is not inherently sinful but that soldiers should conduct themselves with integrity and righteousness.

Christians today hold a range of views on military service. Some believe it is a noble calling to defend one's country and protect the innocent. Others object to participating in war based on their understanding of Jesus' teachings on nonviolence. Many Christian denominations leave the decision up to individual conscience, recognizing the issue's complexity.

According to a Barna study, 55% of active-duty military personnel identify as Christian, suggesting that many Christians do choose to serve in the armed forces.

Biblical Principles for Christians Considering Military Service

Christians considering military service should prayerfully examine biblical principles and seek God's guidance. Fundamental principles to consider include:

  • Loving one's enemies (Matthew 5:44)
  • Turning the other cheek (Matthew 5:39)
  • The apostle Paul's instruction to overcome evil with good (Romans 12:21)

At the same time, the Bible also affirms the role of government in maintaining order and punishing wrongdoing (Romans 13:1-4).

Loving Your Enemies

Jesus taught his followers to love their enemies and pray for those persecuting them (Matthew 5:44). This radical command challenges Christians to respond to hostility with love and seek all people's good, even those considered adversaries.

Turning the Other Cheek

In the Sermon on the Mount, Jesus instructed his disciples, "If anyone slaps you on the right cheek, turn to them the other cheek also" (Matthew 5:39). Some Christians interpret this as a call to absolute nonviolence. In contrast, others understand it as a principle of non-retaliation and a willingness to suffer for one's faith.

Serving with Integrity and Honor

Christians who choose to serve in the military should strive to maintain their integrity, honor, and Christian witness. The apostle Paul urged believers to live lives worthy of the gospel (Philippians 1:27) and to do everything as unto the Lord (Colossians 3:23).

Challenges Christians Face in the Military

Christians serving in the military may face unique challenges, such as:

  • Maintaining their faith in difficult circumstances
  • Dealing with moral dilemmas
  • Finding a Christian community and support

The demands of military life, exposure to violence and suffering, and the complexities of warfare can test one's faith and convictions.

Maintaining Faith in Difficult Circumstances

Military service often involves hardships, separation from loved ones, and exposure to traumatic events. Christians in the military must intentionally nurture their faith through prayer, Bible study, and fellowship with other believers.

Dealing with Moral Dilemmas

Warfare can present complex moral dilemmas, such as the use of force, the treatment of enemy combatants, and the protection of civilians. Christians in the military must wrestle with these issues and seek to apply biblical principles to difficult situations. I've faced my fair share of ethical challenges while in the service. It's not always clear-cut, but I've found that prayer, wise counsel, and a commitment to integrity have helped me navigate these dilemmas with a clear conscience.

Finding Christian Community and Support

Christians in the military need the support and encouragement of fellow believers. Finding a Christian community through military chaplains, on-base Bible studies or online resources can provide vital spiritual nourishment and accountability.

Key Takeaway: Christians can serve in the military, balancing biblical teachings and service with integrity. It's about loving enemies, seeking peace, and living out faith under challenging conditions. Staying connected to Christian communities provides essential support.

The Role of the Military in Promoting Justice and Punishing Evil

As a Christian soldier, I've often wrestled with the tension between Jesus' teachings on peace and the military's role in promoting justice and punishing evil. It's a complex issue that requires careful consideration of biblical principles and real-world realities. While war should always be a last resort, there are times when military force may be necessary to protect the innocent, defend against aggression, and promote good in the face of evil.

The Bible recognizes the legitimate role of government in bearing the sword to punish evildoers and maintain order (Romans 13:1-4). As Christians in the military, we must prayerfully discern when our participation aligns with God's purposes and when it may cross ethical lines.

It's a heavy responsibility that requires wisdom, humility, and a deep commitment to following Christ Jesus.

Protecting the Innocent

One of the primary justifications for military action is the protection of innocent lives. Throughout history, armed forces have been used to defend civilians from violent aggression, intervene in cases of genocide, and provide security in unstable regions.

As a Christian soldier, safeguarding the vulnerable and oppressed is a noble calling. It reflects God's heart for justice and His command to defend the weak (Psalm 82:3-4).

Defending Against Aggression

Another legitimate role of the military is to defend a nation and its allies against unjust aggression. When diplomacy fails, and a country faces an existential threat, armed forces may be necessary to protect lives and preserve freedom. As Christians, we recognize that the world is broken by sin and that evil regimes sometimes pose a clear danger. In such cases, military action may be justified to restrain aggressive evil and promote justice.

Supporting Humanitarian Efforts

Military forces can also play a vital role in supporting humanitarian efforts and promoting human flourishing. From disaster relief to peacekeeping missions, the military's logistical capabilities and manpower can be leveraged for good.

Key Takeaway: Christians can faithfully serve in the military by staying rooted in prayer, being a light to others, and ministering to fellow soldiers. It's about balancing God's teachings with our duties.


So, can Christians join the military? The answer isn't a simple yes or no. It's a personal decision that requires deep reflection, prayer, and seeking God's guidance.

God's Word lauds loyal warriors and directs us to care for our adversaries. Those who follow Christ while serving their country walk a fine line. Darkness surrounds them, yet they can radiate light through their service and witness, even as they confront unparalleled obstacles.

Ultimately, it's about serving with integrity, maintaining your faith, and being a witness for Christ. Whether you feel called to military service or not, remember that your identity is first and foremost in Him.
