obedience: glad, attentive submission that listens to a rightful authority and does what it says
TranslatabilityApproximateCertaintySettled
The word is built from the ordinary verb for hearing. To the writers of the New Testament, obedience is not blind rule-keeping but attentive listening that follows through: you hear a voice you trust and you act on it. The related verb ὑπακούω even pictures a servant who hears a knock and hurries to answer the door. This hearing-then-doing sense reaches back to the Hebrew Scriptures, where obedience is carried by the verb "to hear" (שָׁמַע): to truly hear God is already to obey him.
In Paul's letters the word most often names the whole-life response God's good news calls for. He sums up his mission as bringing the nations to "the obedience of faith" (Romans 1:5), an obedience so bound up with trust that the two can barely be pulled apart. That obedience may be owed to God directly, or shown to those who speak for him: Paul is confident of Philemon's obedience and glad of the Corinthians' obedience to his ministry.
Its weightiest use is the obedience of Christ. Where one man's disobedience brought ruin, "by the one man's obedience the many will be made righteous" (Romans 5:19), and Hebrews says the Son "learned obedience through what he suffered" (Hebrews 5:8), not because he was ever disobedient but because he lived out his trust under real cost.

How the genitive phrase "obedience of faith" (Rom 1:5; cf. 16:26) relates obedience to faith.
majorityA genitive of source: obedience springs from and expresses faith, so trust in the gospel produces a life that heeds God.; C.E.B. Cranfield, The Epistle to the Romans (ICC), on 1:5; Douglas J. Moo, The Epistle to the Romans (NICNT), on 1:5
minorityAn appositional genitive: the obedience consists in faith itself, so believing the gospel is already the obedience God requires.; James D.G. Dunn, Romans 1-8 (WBC 38A), on 1:5
minorityAn objective genitive: obedience directed to "the faith" as the body of gospel truth to be believed and obeyed.; Don B. Garlington, 'The Obedience of Faith': A Pauline Phrase in Historical Context (WUNT 2/38)
1bobedience shown to those who speak with God-given authority, such as compliance with an apostle's instruction
2Co 7:152Co 10:6Phm 1:21
1cthe obedience of Christ: his faithful submission to the Father, enacted for others and learned through suffering
Names obedience as a settled disposition and hallmark of the believer, not a single act: the state of life the gospel aims to produce among the nations and the mark of a whole community.Rom 1:5Rom 16:191Pe 1:14
Points to Christ's own redemptive obedience as a decisive fact of salvation, a use the concrete verb never carries.Rom 5:19Heb 5:8
Both
Both describe yielding to a master's authority: in Romans 6:16 a person is the slave of the one they obey, and that yielding issues in the settled state of obedience that leads to righteousness.Rom 6:16
Names the concrete act of one party heeding another's authority, often nature or subordinates submitting to a specific command: the winds and sea obey Christ, children obey parents, servants obey masters, Abraham obeys and departs.Mat 8:27Eph 6:1Col 3:22Heb 11:8
Can carry the plain everyday sense of heeding a summons, stretching to answering a knock at the door rather than any moral submission.Act 12:13
ὑποταγήsubjection is placing oneself under someone's rank or order; obedience is heeding and doing what that authority commands.
Obedience is the doing of what a command or message says. It is measured by whether the thing was actually carried out, in word and in deed.Rom 15:18Phm 1:21
It attaches to a specific word that must be heeded and acted on, so the gospel and the truth are things one obeys, and every thought is brought into line to obey Christ.Rom 1:52Co 10:5
Even Christ rendered this kind of obedience, learning it through what he suffered by actually doing his Father's will.Heb 5:8
Both
Both name a person yielding to a rightful authority instead of resisting it, and both can describe that yielding offered to God and the gospel.Rom 6:162Co 9:13
Submission is taking one's assigned place under another within an ordered relationship, ranking oneself beneath the one in charge rather than performing a particular task.1Ti 2:111Ti 3:4
Because it is about standing and place, it can be refused to hold one's ground: Paul would not yield his position for even an hour to protect the freedom of the gospel.Gal 2:5
hupakoē in the other biblical languages
שָׁמַעHebrew“to hear: hear”Hebrew expresses obedience with the verb "to hear, heed," with no separate noun, so for the Old Testament listening and obeying are one act.
A dedicated abstract noun that names obedience as a settled thing in its own right, something a person belongs to, is brought into, or grows in, rather than a single act of complying.Rom 6:16Heb 5:8
Carries the fixed gospel phrase "the obedience of faith," where the noun frames the whole faithful response to God as one enduring posture of obedience.Rom 1:5Rom 16:19
Both
Both root obedience in hearing: the Hebrew verb slides from "hear" to "heed" a voice, and the Greek noun is built from the same idea of hearing under authority, so each ties submission to attending to what a rightful voice says.Gen 22:18Rom 1:5
The same verb is first ordinary physical hearing, so its "obey" sense is one end of a range that begins with the ear; a single word covers catching a sound and heeding it.Gen 3:8Gen 21:17
Stretches to senses a word for obedience never touches, such as understanding a spoken language or God granting an answer to a request.Gen 11:7Gen 30:22
What scholars say about hupakoē
ὑπακοή is a verbal noun from ὑπακούω ("to listen to, obey"), itself a compound of ἀκούω ("to hear") with ὑπό. The lexica are uniform on the sense: obedience, compliance, submission (BDAG). The word-group study in TDNT (G. Kittel, s.v. ἀκούω κτλ.) stresses that biblical obedience is grounded in hearing, so that hearkening to a word and obeying it are inseparable, a continuity with the Hebrew שָׁמַע. In Paul the term is heavily concentrated in Romans and clusters around three foci: the obedience owed to God and the gospel (the programmatic ὑπακοὴ πίστεως of Rom 1:5 and 16:26), obedience to apostolic authority (2 Cor 7:15; 10:6; Phlm 21), and the representative obedience of Christ set antithetically against Adam's παρακοή (Rom 5:19), echoed by the Son's learned obedience in Heb 5:8. The one sustained exegetical debate concerns the genitive in ὑπακοὴ πίστεως: a genitive of source (obedience produced by faith), an epexegetical/appositional genitive (obedience that is faith), or an objective genitive (obedience to "the faith"); see Cranfield, Moo, Dunn, and Garlington's monograph.
