In depth

From the study of Ephesians 2:2

Range of meaning

To be at work, to be effective, to put power into action. It is related to energeia ("working power"). In the New Testament it usually describes supernatural power, whether God's or an opposing one.

Against the English

"Worketh" (KJV), "is at work" (BSB, ESV, NIV), "is working" (YLT). All are accurate. English "work" is weaker than the Greek, which suggests energising power.

Used elsewhere in the period

Ephesians 1:11 (God "works all things"), 1:19–20 ("the working of his mighty strength, which he worked in Christ"), 3:20 ("the power at work in us"); 2 Thessalonians 2:7, 9 (the "mystery of lawlessness" at work and Satan's "working").

From the study of Ephesians 3:20

Range of meaning

To be at work, to operate, to be effective, to produce results. The middle form used here, energeomai, usually describes a force or influence doing its work.

Against the English

KJV "worketh" and BSB/NIV "is at work" are accurate. The English "energy" comes from this root, but the Greek focuses on effective operation, not stored potential.

Used elsewhere in the period

Ephesians uses this word family on purpose: God "works" (energeō) all things by the counsel of his will (1:11). His power "worked" (energeō) in Christ in raising him (1:19–20). An opposing spirit "is now at work" (energeō) in the disobedient (2:2). Paul received grace "by the working (energeia) of his power" (3:7).

From the study of James 5:16

Range of meaning

From ἐνεργέω, 'to be at work, to operate, to produce an effect' (root ergon, 'work'; English 'energy' comes from the same family). In the New Testament the active voice usually has God or a spiritual power as its subject (God 'works' in you, Phil 2:13; Gal 2:8). The middle-passive form, as here, usually has an impersonal subject and means 'is at work, is operative': the gospel or God's word 'at work in you' (1 Thess 2:13), 'faith working through love' (Gal 5:6), death 'at work' in us (2 Cor 4:12), the passions 'at work' in our members (Rom 7:5).

Against the English

The KJV's 'effectual fervent' turns one Greek participle into two English adjectives, and 'fervent' (from Latin fervere, 'to boil') brings in emotional heat that the word does not carry. Modern versions split: 'effective' (NASB), 'powerful and effective' (NIV), 'as it is working' (ESV), 'earnest' (NLT), 'insistent' (WEB). 'Earnest' and 'insistent' carry over the old 'fervent' tradition; 'working' and 'effective' stay closer to the Greek.

How it drifted

The Latin Vulgate rendered the idea with assidua ('persistent, constant'). Tyndale (1526) and the Geneva Bible had 'if it be fervent'. The KJV (1611) kept 'fervent' and added 'effectual', so English readers have heard 'fervent' for four centuries. The phrase 'effectual fervent prayer' then passed into revival and prayer-meeting language as a description of intense, passionate praying.

Used elsewhere in the period

Paul's letters use the middle-passive form repeatedly for something operating with inner force (1 Thess 2:13; 2 Cor 1:6; Gal 5:6; Eph 3:20; Col 1:29). Hellenistic Greek used ἐνέργεια for the active working of divine or natural powers. Nothing in this usage means 'fervent' in the emotional sense.

Where it appears

Matthew · 1
  1. Matthew 14:2 ἐνεργοῦσιν are working

    and said to his servants, “This is John the Baptist; he has risen from the dead! That is why miraculous powers are at work in him.”

    Here: Present tense, ongoing: the powers are actively operating. Elsewhere the verb is often used of unseen forces at work in a person.

Mark · 1
  1. Mark 6:14 ἐνεργοῦσιν operate

    Now King Herod heard about this, for Jesus’ name had become well known, and people were saying, “John the Baptist has risen from the dead! That is why miraculous powers are at work in him.”

    Here: 'Are actively working.' The powers are the subject. They are pictured as forces operating inside the man, not simply as deeds he performs.

Romans · 1
  1. Romans 7:5 ἐνηργεῖτο were at work

    For when we lived according to the flesh, the sinful passions aroused by the law were at work in our bodies, bearing fruit for death.

    Here: Imperfect tense: the passions kept on operating. Paul tends to use this verb for forces that work inside a person, as in "death is at work in us" (2 Cor 4:12). The passions are pictured as an active power working through the body.

1 Corinthians · 2
  1. 1 Corinthians 12:6 ἐνεργῶν is working

    There are different ways of working, but the same God works all things in all people.

    Here: A present participle: God is continually and actively at work. It shares a root with energēmata, which makes a wordplay: the "workings" are what "the Worker" works.

  2. 1 Corinthians 12:11 ἐνεργεῖ works

    All these are the work of one and the same Spirit, who apportions them to each one as He determines.

    Here: Present tense: the Spirit is the one actively producing these effects, again and again. It is the same verb used of God in verse 6 ("God who works all things in all"), so what God does, the Spirit does.

2 Corinthians · 2
  1. 2 Corinthians 1:6 ἐνεργουμένης is operating

    If we are afflicted, it is for your comfort and salvation; if we are comforted, it is for your comfort, which accomplishes in you patient endurance of the same sufferings we experience.

    Here: "Which is actively at work." The comfort is not just a feeling. It is an active force that shows itself in their endurance. Paul uses this form elsewhere for forces that work inside people (Rom 7:5; Gal 5:6).

  2. 2 Corinthians 4:12 ἐνεργεῖται, works,

    So then, death is at work in us, but life is at work in you.

Galatians · 4
  1. Galatians 2:8 ἐνεργήσας ἐνήργησεν having worked, did

    For the One who was at work in Peter’s apostleship to the circumcised was also at work in my apostleship to the Gentiles.

    Here: A past (aorist) participle: "the one who was at work." It means active, effective power that produces results. Paul nearly always uses this verb for God's power working in people (1 Cor 12:6; Gal 3:5; Phil 2:13).

  2. Galatians 3:5 ἐνεργῶν working

    Does God lavish His Spirit on you and work miracles among you because you practice the law, or because you hear and believe?

    Here: 'Who keeps working'. Like 'supplying', it is in the present tense, so it describes something still happening. Paul often uses this verb for God's power actively at work (Gal 2:8; 1 Cor 12:6, 11).

  3. Galatians 5:6 ἐνεργουμένη. working.

    For in Christ Jesus neither circumcision nor uncircumcision has any value. What matters is faith expressing itself through love.

    Here: A present participle describing faith. Most scholars take it as middle voice, meaning faith acts on its own account: 'working', 'being operative', 'putting itself into effect'. The present tense pictures ongoing activity. The English word 'energy' comes from this root.

Ephesians · 4
  1. Ephesians 1:11 ἐνεργοῦντος working

    In Him we were also chosen as God’s own, having been predestined according to the plan of Him who works out everything by the counsel of His will,

    Here: Present participle: the One who is actively and continually at work in all things, bringing them about. The same word-family describes God's power raising Christ in verses 19–20.

  2. Ephesians 1:20 ἐνήργησεν He worked

    which He exerted in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly realms,

    Here: 'He put into effect, set to work.' The verb comes from the same root as energeia in v.19, so Paul says God 'worked the working' of his strength. The past tense points to one definite event: Easter and what followed it.

  3. Ephesians 2:2 ἐνεργοῦντος working

    in which you used to walk when you conformed to the ways of this world and of the ruler of the power of the air, the spirit who is now at work in the sons of disobedience.

    Here: "Actively working, energising." Ephesians uses the same verb for God's power at work in raising Christ (1:11, 20) and in believers (3:20). Two rival powers are at work.

  4. Ephesians 3:20 ἐνεργουμένην is working

    Now to Him who is able to do immeasurably more than all we ask or imagine, according to His power that is at work within us,

    Here: "Being at work" or "operating". The present tense says this power is active now, not waiting to start. It is the root of English "energy", though the Greek means effective working, not stored force.

Philippians · 2
  1. Philippians 2:13 ἐνεργῶν ἐνεργεῖν working, to work

    For it is God who works in you to will and to act on behalf of His good purpose.

    Here: Present participle: God is continually and effectively at work. Paul uses this verb mostly of God's power actually operating and getting results, not of mild influence.

Colossians · 1
  1. Colossians 1:29 ἐνεργουμένην is working

    To this end I also labor, striving with all His energy working powerfully within me.

    Here: From the same root as energeia, so the Greek says 'his working that is working'. The present tense means it is happening now and keeps on happening. Paul usually uses the middle form of this verb to mean 'is at work' rather than 'is made to work'.

1 Thessalonians · 1
  1. 1 Thessalonians 2:13 ἐνεργεῖται works

    And we continually thank God because, when you received the word of God that you heard from us, you accepted it not as the word of men, but as it truly is, the word of God, which is also now at work in you who believe.

    Here: Present tense: 'is at work, keeps working'. The message is a living, active force in the community, not inert information.

2 Thessalonians · 1
  1. 2 Thessalonians 2:7 ἐνεργεῖται is working

    For the mystery of lawlessness is already at work, but the one who now restrains it will continue until he is taken out of the way.

    Here: Present tense, middle voice: 'is actively at work.' Paul usually uses this word for power that comes from beyond the human. It looks ahead to verse 9, where the lawless one comes 'according to the working (energeia) of Satan.'

James · 1
  1. James 5:16 ἐνεργουμένη. being made effective.

    Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man has great power to prevail.

    Here: A participle describing the petition: '(when it is) at work / in its working', or possibly '(when it is) put to work (by God)'. It is about the prayer's effectiveness, not its emotional heat.
