Dunamis-meaning
Short answer: Dunamis is the Greek noun usually translated power in the New Testament. It does not mean raw force or personal clout. It means effective, working power: ability that actually accomplishes what God intends. Luke 24:46-49 ties this power to the risen Christ and to the Spirit he promises to send. Acts 1:8 says, "But you will receive power when the Holy Spirit has come upon you. You will be witnesses to me in Jerusalem, in all Judea and Samaria, and to the uttermost parts of the earth." Romans 1:16 calls the gospel itself the power of God for salvation, and 1 Corinthians 1:18 calls the word of the cross the power of God to those being saved. So dunamis is not a vague spiritual energy. In the New Testament it is God's own power, at work in the resurrection, in the gospel message, in the Spirit, and in the lives of believers.
What dunamis actually means in Greek
Dunamis belongs to the same family as the verb dynasthai, which means to be able, and the adjective dynatos, which means capable or strong. The core idea is capability that produces an effect. A person with dunamis has the capacity to do something, and the word often carries the sense of that capacity being put to work.
This is why the related English word dynamite is a misleading shortcut. Dynamite is explosive and destructive, but the New Testament word describes power that heals, saves, raises, and enables witness. It is not merely potential energy sitting unused. It is power expressed in action.
In ordinary Greek usage dunamis could describe military strength, miraculous deeds, or the power of a ruler. The New Testament writers take that ordinary word and apply it to God. He is the one whose power is real, effective, and never frustrated by human weakness or opposition.
Dunamis in Luke 24 and Acts 1: promise before power
In Luke 24:46-49 Jesus interprets his death and resurrection from the Scriptures and then tells the disciples they are witnesses of these things. He also tells them to stay in the city until they are clothed with power from on high. The power is not something they generate. It is promised, awaited, and received.
Acts 1:8 makes the connection explicit, naming the Holy Spirit as the one through whom this power comes. The disciples were not told to manufacture boldness or to work up confidence. They were told to wait, because the power they needed would arrive as a gift.
That ordering matters for how we read the rest of Acts. The church does not begin with a strategy meeting. It begins with a promise and a prayerful wait, and then the Spirit comes. Dunamis in this context is inseparable from the Spirit's presence and from the mission he empowers.
The gospel itself is dunamis
Romans 1:16 says, "For I am not ashamed of the Good News of Christ, because it is the power of God for salvation for everyone who believes, for the Jew first, and also for the Greek." Paul does not say the gospel contains power or illustrates power. He says it is the power of God for salvation.
That claim is striking because the message is so ordinary: a crucified and risen Messiah, announced in words. There is no impressive display attached. Yet Paul insists that when this message is proclaimed and believed, God's effective power is at work, accomplishing salvation in real people.
This means the power is not located in the preacher's charisma, the setting, or the technique. It is located in the message and in the God who acts through it. A plain sermon can carry the same power as a dramatic one, because the power belongs to the gospel, not the delivery.
1 Corinthians 1:18 and the power of the cross
1 Corinthians 1:18 says, "For the word of the cross is foolishness to those who are dying, but to us who are being saved it is the power of God." Here dunamis stands directly opposite human expectations of what power looks like. The cross looked like defeat, shame, and the end of a movement.
Paul's point is that God's power does not fit the world's categories. The world looks for signs and wisdom, strength and status. God works through a crucified Messiah, and that apparent weakness turns out to be the very means by which sin and death are broken.
So dunamis in 1 Corinthians is not just a general attribute of God. It is the specific power by which he saves, and it is exercised precisely where human power failed. The cross is not the interruption of God's power. It is the display of it.
Ephesians 1:19-20: power toward us who believe
Ephesians 1:19-20 speaks of "the exceeding greatness of his power toward us who believe, according to that working of the strength of his might." Paul piles up terms here because he wants the readers to grasp the scale of what God has done for them. The power in view is not abstract. It is directed toward believers.
The standard for that power is the resurrection. The same strength that raised Christ from the dead and seated him at God's right hand is the strength at work on behalf of his people. That is an extraordinary comparison, and Paul makes it deliberately.
This means the power available to Christians is not measured by their own resources or circumstances. It is measured by an event that already happened: the raising of Jesus from the dead. Whatever believers face, the benchmark of God's power toward them has already been set.
Philippians 3:10 and knowing the power of his resurrection
Philippians 3:10 reads, "that I may know him, and the power of his resurrection, and the fellowship of his sufferings, becoming conformed to his death." Paul longs to know Christ, and he joins the power of the resurrection to the fellowship of sufferings in the same breath.
That pairing is important. Paul does not treat resurrection power as a way to avoid hardship. He treats it as the power that sustains him through hardship and will finally raise him, just as it raised Christ. The power is real now and completed later.
So dunamis in Philippians is personal and experiential. It is not merely a doctrine to affirm, but something Paul wants to know, and knowing it is bound up with following Christ through suffering rather than around it.
How dunamis differs from other New Testament power words
The New Testament uses several words that English Bibles render as power, and they are not interchangeable. Kratos often emphasizes dominion or ruling strength. Ischys often emphasizes physical strength or might. Exousia usually means authority, the right to act. Dunamis emphasizes effective capability, power that gets something done.
Ephesians 1:19-20 uses several of these terms together, which is why some translations read working, strength, and might in a single sentence. The accumulation is not redundancy. It is an attempt to convey the magnitude of God's action in raising Christ and applying that action to believers.
Recognizing the distinction helps readers see why dunamis is used so often for miracles and for the gospel. Both involve power that produces an observable effect, whether a healed body or a converted heart. The word is chosen for its sense of accomplished work.
What dunamis does not mean
Dunamis does not mean that believers now possess power as a personal possession to command at will. In the New Testament, power is consistently tied to God, to the Spirit, and to the gospel. It is received and depended upon, not stored and deployed.
It also does not guarantee that faithful Christians will experience constant victory, comfort, or visible success. Paul spoke of knowing resurrection power while also describing suffering and conformity to Christ's death in Philippians 3:10. The two belong together in this present age.
And dunamis is not a technique for manipulating spiritual outcomes. It is not a formula attached to certain words or methods. Where the New Testament speaks of power, it speaks of God acting, often through weak and ordinary means, to accomplish what only he can accomplish.
Biblical fidelity check
These passages establish several things plainly. God's power is real and effective. It is displayed supremely in the resurrection of Jesus. It is present in the gospel message, in the Holy Spirit given to the church, and in the lives of believers who trust Christ. Luke 24:46-49 and Acts 1:8 connect this power to witness, Romans 1:16 and 1 Corinthians 1:18 connect it to salvation, and Ephesians 1:19-20 and Philippians 3:10 connect it to the risen Christ and to Paul's own experience.
What these passages do not establish is a promise that believers may claim miraculous power on demand, or that outward displays of power are a reliable measure of spiritual maturity. A common misreading treats dunamis as a spiritual force that strong Christians learn to wield, as though the word named a personal possession. That reading contradicts the way the New Testament consistently presents power as God's own action, received by faith and dependent on the Spirit, often working through suffering and apparent weakness rather than around them.

Several related studies help place this theme in its wider biblical context. What Does 1 Corinthians 1:10 Mean? Context, Theology, and Application explores the call to unity in a divided church. What Does 1 Corinthians 1:9 Mean? Context, Theology, and Application examines God's faithfulness as the ground of Christian calling. 1 Corinthians 1: Called, United, and Boasting in the Lord surveys the whole chapter, including the power of the cross. 1 Corinthians 10: Warnings and Freedom traces how power and temptation meet in the life of the church.
Frequently asked questions
Does dunamis mean dynamite in the New Testament?
No. English dynamite comes from the same Greek root, but the New Testament word means effective capability, not explosive force. Dunamis describes power that accomplishes God's purposes, such as raising the dead, saving believers, and equipping witnesses. Dynamite carries overtones of destruction that the biblical usage does not carry. The resemblance between the words is a matter of shared etymology, not of shared meaning. Reading dynamite back into passages like Acts 1:8 or Romans 1:16 distorts the sense rather than clarifying it.
Is dunamis the same as authority in the New Testament?
No, they are distinct terms. Dunamis refers to effective power or capability, while exousia refers to authority, the right or permission to act. A person could have authority without the power to enforce it, or power without legitimate authority. The New Testament often uses the words side by side, which shows they are not synonyms. When Jesus gives his disciples authority over unclean spirits, the words used highlight different aspects of what he grants. Keeping the terms distinct helps readers follow the New Testament's precision.
How does dunamis apply to ordinary Christians today?
Acts 1:8 ties the gift of power to witness, not to personal prestige or spectacle. Romans 1:16 locates power in the gospel itself, so any believer who shares that message shares in something God promises to use. Ephesians 1:19-20 measures the power toward believers by the resurrection, which means it is already secured regardless of circumstances. Faithful Christians may differ over how dramatically this power is experienced today, but the New Testament consistently directs believers to depend on God's power rather than to claim it as their own.
