Dualism – What is it?

WHAT DOES THE BIBLE SAY?

Dualism is the belief that reality is divided into two fundamental, opposing principles, such as good and evil, light and darkness, or spirit and matter. In many ancient forms, these principles were treated as rival forces that shaped the world. This way of thinking appeared in several historical systems, including Persian religious thought, Gnostic movements, and philosophies that viewed the physical world as inherently flawed or evil in contrast to the good spiritual realm.

Scripture rejects all forms of dualism, teaching that God alone is sovereign and who created all things (Genesis 1:1ff). Evil does not rival God’s power, nor is it an eternal principle He battles, but is the corruption of what He made (Isaiah 45:5–7; James 1:13–15). Even Satan, the most evil figure in creation, is limited by God and remains under His authority (Job 1:6–12; Luke 4:6).

Because God alone is ultimate, human beings are accountable to Him for their sin. Evil is rebellion within creation that God will judge and decisively end. People are called to repent and trust in Jesus, whom God appointed as Judge and Savior, before that final judgment takes place (Acts 17:24–31; Revelation 20:10).

FROM THE OLD TESTAMENT

• In contrast to dualistic ideas, Scripture says that there is only one eternal truth, and that is God. He created everything else that exists (Genesis 1:1ff). This means that nothing in creation exists independently of Him or is capable of competing against His authority. He said, “I am the LORD, and there is no other, besides me there is no God; I equip you, though you do not know me, that people may know, from the rising of the sun and from the west, that there is none besides me; I am the LORD, and there is no other. I form light and create darkness; I make well-being and create calamity; I am the LORD, who does all these things” (Isaiah 45:5–7).
• Even Satan, the most prominent and evil figure, is still just a creature. This means that he operates under God’s authority. We see this in the book of Job, where Satan has to ask God’s permission to do evil and remains restricted by the limits God sets (Job 1:6–12; 2:1–6). Satan, then, is no more a threat to God than any other creature.
• As the only ultimate authority, God will one day judge all rebellion decisively. The book of Daniel describes God as the ruler who removes and establishes kings, directing the course of history according to His will (Daniel 2:20–21). Daniel prophesies of the final kingdom where God sits in judgment over the Earth (Daniel 7:9–14). The last chapter of the book notes that everyone will be raised from the dead, with many facing eternal condemnation for their attempted rebellion in this life (Daniel 12:2).

FROM THE NEW TESTAMENT

• Dualism posits that evil is a force that is just as powerful as good. But Scripture shows that Satan and his demons are created beings and that God limits what Satan can do. When Jesus expelled the demons from the man of the Gerasenes, the demons begged to be sent into the herd of pigs rather than to “the abyss” (Luke 8:30-31), showing that the demons are subject to Jesus.
• The apostle John wrote that “he who is in you is greater than he who is in the world” (1 John 4:4). “[H]e who is in” believers is the Holy Spirit, and the Holy Spirit is greater than Satan.
• This limitation has made it possible for God’s children to resist Satan (1 Corinthians 10:13; James 4:7).
• Unlike God, Satan is not timeless, and one day, he will be destroyed (Revelation 12:9-12).

IMPLICATIONS FOR TODAY

TV and movies often paint life as one ongoing battle between good and evil. In some stories, this is openly dualistic, such as in Star Wars, while in others it is more subtle. In each, evil must be overcome, and the outcome often depends on who gains the upper hand. While that makes for a compelling story, reality is different. The universe was created by God. Nothing exists outside what He made, which means He alone has the final authority.

We live in a world filled with evil. But Christians are not dualists; we don’t believe that evil forces have equal power to God. God is sovereign over all forces, and evil forces have already been defeated by Jesus’ death and resurrection–they are just awaiting their final judgment. Being indwelt by the Holy Spirit, believers are equipped to resist demonic forces. We should take advantage of the means God has given to guard against evil (Ephesians 6:10-20), such as His Word, fellowship with other believers, and our mission to share the Gospel with unbelievers. Evil exists, but we do not need to fear it. Our God is greater.

UNDERSTAND

• Dualism claims good and evil are equal forces; the Bible says God alone is sovereign.
• Evil and Satan are created and limited, not rivals to God.
• Believers can resist evil through the Spirit, knowing God will judge all rebellion.

REFLECT

• How does knowing that God alone is sovereign change the way you view evil?
• In what ways do you rely on God’s Spirit to resist temptation or spiritual attacks?
• How does understanding that evil is created and limited affect your trust in God?

ENGAGE

• How can we help each other recognize that evil is not equal to God’s power?
• How can we use the Bible, prayer, and fellowship to resist spiritual forces?
• How does the reality of God’s ultimate judgment motivate us to live faithfully and share the Gospel with others?
