What is the difference between power and might?

In biblical language, "power" and "might" are closely related, yet not entirely identical concepts. Together, they glorify God as the One who possesses the ability to act and the inexhaustible strength to bring His will to completion.

In the heavenly worship of the book of Revelation, these words stand side by side for a reason. They do not describe two different gods or two independent forces, but rather display the fullness of God's majesty. The Lord is not only able to save, protect, and overcome evil; His strength is also unshakeable, never depleted, and never dependent on circumstances.

“Amen! Blessing and glory and wisdom and thanksgiving and honor and power and might be to our God forever and ever! Amen.” Rev 7:12

Power: God's ability to act

The word "power" points primarily to active, effective strength: the ability to accomplish something. God reveals His power in creation, providence, the deliverance of His people, the forgiveness of sin, and the resurrection of the dead. This is not an abstract energy, but the holy power of a personal God who acts with wisdom, love, and justice.

The apostle Paul especially connects God's power with the resurrection of Christ. The very same power that raised Jesus from the grave is at work within those who believe. Thus, God's power is not merely a subject for theological reflection: it gives the believer hope for a transformed life and the ultimate victory over death.

“And what is the immeasurable greatness of his power toward us who believe, according to the working of his great might that he worked in Christ when he raised him from the dead.” Eph 1:19–20

When we say that God has power, we acknowledge that with Him there are no hopeless situations. He is able to accomplish what He has promised, even when human resources have been completely exhausted.

Might: steadfast and inexhaustible strength

"Might" or "strength" emphasizes endurance, inherent power, and God's supremacy over all the forces of evil. While "power" often draws attention to action, "might" reminds us of the unbreakable source of that action. God never loses authority, never grows weary, never falters, and can never be defeated.

In the Greek text of Revelation, two related yet distinct terms are used for these words: δύναμις (dynamis): power, capability, mighty deed; ἰσχύς (ischys): might, strength, inherent power characterizing one who is mighty. We should not draw an overly rigid boundary between them, as biblical authors often combine similar words to intensify praise. Nevertheless, a nuance remains: God is both omnipotent in His deeds and invincible in His nature and authority.

“Finally, be strong in the Lord and in the strength of his might.” Eph 6:10

A believer is not called to overcome sin and temptation merely through personal willpower. God's might becomes an anchor for the one who relies on Christ, seeks Him daily in prayer, and obediently lives by His Word.

Why does heavenly praise mention both words?

Revelation 7:12 is a song of worship. The heavenly multitude is not compiling a technical glossary of divine attributes; they are confessing His limitless grandeur. "Power and might" together mean that God possesses the total capability to accomplish His plan of salvation and will never suffer defeat in the conflict against evil.

This is especially significant in light of the great controversy between Christ and Satan. Evil may appear strong, and God's people may seem weak, but the final word belongs to the Lord. His power works throughout history, and His might guarantees the ultimate triumph of righteousness.

“Have you not known? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He does not faint or grow weary; his understanding is unsearchable. He gives power to the faint, and to him who has no might he increases strength.” Isa 40:28–29

What this means for our lives

The difference can be summarized briefly: power is God’s ability to act mightily, while might is His unbreakable, enduring strength that never runs dry. In doxology, however, these concepts blend into one magnificent truth: God is fully able to save His people and will faithfully complete what He has begun.

The practical application is simple: whenever you feel weak, do not focus merely on your own resources. In prayer, bring your specific need before the Lord, entrust to Him what you cannot change, and take the next right step of faith. God provides the power for today’s obedience and the might to endure to the very end.
