The inherent, operative power of God — not merely His capacity to act but His actual energy in motion. Dunamis is distinguished from exousia (authority, the right to act) in that dunamis is the force itself. When Jesus said "You shall receive power (dunamin) when the Holy Spirit has come upon you" (Acts 1:8), He was not granting a title or permission but an explosive, transformative energy. The gospel itself is "the dunamis of God for salvation" (Rom. 1:16) — not merely information about salvation but the very force that accomplishes it. In Scripture, dunamis manifests as miracles (Acts 2:22), resurrection power (Phil. 3:10), the sustaining force of creation (Heb. 1:3), and the inner strength that enables believers to endure what human willpower cannot (Eph. 3:16, Col. 1:11).
POWER, n. [L. potentia; Fr. pouvoir.] 1. In a general sense, the faculty of doing or performing any thing; the faculty of moving or of producing a change in something; ability or strength. 2. Force; animal strength. 3. The power of God, supreme energy or ability; omnipotence. 4. Influence; that which may move or impel the mind. 5. Ability, physical or moral. 6. The right of governing, or actual government; dominion; rule; authority. — Webster carefully distinguished "power" (ability/force) from "authority" (right/commission), mirroring the dunamis/exousia distinction in Greek.
Modern Christianity has either over-spiritualized or under-spiritualized dunamis. Cessationists reduce it to a historical curiosity — power was for the apostolic age, not for today. Hyper-charismatics treat it as a commodity to be manipulated — "releasing the power," as if God's energy were an impersonal force subject to human technique. Both errors miss the relational nature of dunamis: it flows from intimacy with Christ, not from formulas or nostalgia. Secular culture stripped the word entirely — "dynamic" now describes a sales personality, and "power" means political leverage. The biblical concept — a living, holy, unpredictable force emanating from the Creator — has been reduced to a metaphor.

Alfred Nobel named his invention "dynamite" from dunamis — an unwitting theological commentary: the power of God is explosive, world-altering, and irreversible.
Dunamis answers the great question of the Christian life: "How?" How do you love your enemy? How do you endure suffering? How do you mortify sin? Not by willpower but by power — the dunamis of the Spirit.
The distinction between dunamis and exousia is critical for understanding Christ's ministry: He had both the power (dunamis) to heal and the authority (exousia) to forgive sins. The Pharisees questioned His authority; they could not deny His power.
