5.12 Spiritual Warfare
Christianity often describes life as a spiritual battle. When many people hear the phrase spiritual warfare, they immediately think of demons, exorcisms, curses, possession, or supernatural conflict. Those subjects do appear in some Christian traditions, but the New Testament often presents spiritual warfare in a broader and more practical way.
At its core, spiritual warfare concerns the struggle between truth and falsehood, faithfulness and rebellion, love and hatred, virtue and vice, God’s will and competing loyalties. It is a conflict over what rules the human heart, mind, conscience, and life.
Throughout Christian history, believers have understood this struggle in different ways. Some Christians understand spiritual warfare primarily as a conflict between angels and demons. Others emphasize the internal battle against temptation, selfishness, pride, resentment, fear, addiction, deception, and destructive habits. Still others believe both dimensions are present. Despite these differences, most Christians agree that spiritual warfare concerns the struggle between influences that draw human beings toward God and influences that pull them away from Him.
Spiritual Warfare as Loyalty
One of the central questions of Christianity is:
Who or what rules your life?
The Bible repeatedly presents human beings as serving something. A person may serve wealth, power, pleasure, status, fear, resentment, approval, or God. For this reason, spiritual warfare is often portrayed as a battle over loyalty. The question is not only whether a person believes certain religious ideas. The deeper question is what occupies the highest place in that person’s life.
Jesus frequently called people to examine what ruled them. He taught that no one can serve two masters. He warned against allowing wealth, anxiety, pride, social approval, or worldly ambition to take the place that belongs to God. Spiritual warfare is therefore not merely about resisting external threats. It is about determining what ultimately governs a person’s thoughts, desires, priorities, and actions.
The battle is not only around us. It is also within us.
Spiritual Warfare as Character Formation
The New Testament frequently contrasts two different ways of life. One way produces hatred, envy, greed, selfish ambition, deception, violence, arrogance, and corruption. The other produces love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.
Christians often describe this contrast as a spiritual struggle because every person experiences competing desires. People may know what is right and still choose what is wrong. They may desire truth while protecting a lie. They may want peace while feeding resentment. They may desire freedom while remaining attached to destructive habits. The human person is often divided, and spiritual warfare names the struggle over which pattern of life will become dominant.
For this reason, spiritual warfare is closely connected to character formation. It is not only the struggle to avoid evil. It is the struggle to become the kind of person God intends human beings to be. It is the movement from deception toward truth, from fear toward courage, from selfishness toward faithfulness, and from hatred toward love.
Spiritual Warfare in the Teachings of Jesus
Jesus consistently directed His followers’ attention toward God, truth, repentance, prayer, faithfulness, and the Kingdom of God.
When Jesus confronted temptation, He responded with truth. When He encountered hypocrisy, He exposed it. When He encountered suffering, He brought healing. When He encountered evil, He overcame it through obedience to God. This pattern appears repeatedly throughout the Gospels. Jesus does not teach His followers to obsess over darkness. He teaches them to pursue light.
This is important because some people approach spiritual warfare with fear, suspicion, or obsession. They begin looking for demons behind every emotion, every problem, every illness, every temptation, or every disagreement. The New Testament does not present fear or demon-hunting as the center of the Christian life.
For this reason, many Christians understand spiritual warfare as the daily decision to align one’s life with God’s will instead of competing influences. The battle is fought in what a person loves, believes, says, refuses, forgives, confesses, pursues, and obeys.
The Armor of God
One of the most famous discussions of spiritual warfare appears in Ephesians 6, where the Apostle Paul encourages believers to put on what he calls the Armor of God. This armor includes the belt of truth, the breastplate of righteousness, the shoes of the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the word of God.
It is notable that each piece of armor is connected to a virtue, belief, or spiritual practice. Truth, righteousness, peace, faith, salvation, Scripture, and prayer are presented as the things that protect and strengthen the believer. These are not weapons of domination. They are stabilizing forces that help a person remain faithful when confronted by temptation, deception, fear, suffering, or opposition.
This passage shows that spiritual warfare is not about attacking other people. It is about standing firm. It is about remaining faithful to God when forces inside or outside the person attempt to pull them away from truth, righteousness, and peace.
Spiritual warfare is therefore not only about what a person opposes. It is also about what a person becomes.
The goal is not merely to defeat darkness. The goal is to become a person increasingly shaped by truth, love, holiness, and the Kingdom of God.
Sources of Spiritual Opposition
When Christians discuss spiritual warfare, the New Testament describes several different sources of opposition. Not every struggle is attributed to demons or evil spirits.
- One source is the flesh. The flesh refers to the biological drives, instincts, appetites, and impulses that are part of human nature. These drives are not evil in themselves, but when they rule a person rather than being ordered by wisdom, truth, and love, they can pull a person away from God’s purposes.
- A second source is the world. The world refers to the social pressures, cultural values, group expectations, and collective systems that shape how people think, desire, and behave. In the New Testament, “the world” often describes the surrounding order of society when it trains people to pursue status, power, wealth, approval, or self-protection instead of the Kingdom of God.
- A third source is the spiritual realm. The spiritual realm refers to the organizing loyalties, patterns, meanings, and ruling principles that direct human life either toward truth or falsehood. Human beings do not only act from instinct or social pressure; they also live according to what they worship, love, fear, trust, and serve.
Because these sources can overlap, Christians emphasize discernment. A person struggling with anger, fear, greed, or temptation should not automatically assume the cause is demonic. Spiritual warfare involves learning to recognize the difference between personal weakness, unhealthy cultural and environmental influences, and whatever spiritual realities may also be involved.
