Now to him who is able to strengthen you according to my gospel and the proclamation about Jesus Christ, according to the revelation of the mystery kept silent for long ages 26 but now revealed and made known through the prophetic Scriptures, according to the command of the eternal God to advance the obedience of faith among all the Gentiles—27 to the only wise God, through Jesus Christ—to him be the glory forever! Amen. (CSB Rom. 16:25–27)

Therefore, brothers and sisters, in view of the mercies of God, I urge you to present your bodies as a living sacrifice, holy and pleasing to God; this is your true worship. 2 Do not be conformed to this age, but be transformed by the renewing of your mind, so that you may discern what is the good, pleasing, and perfect will of God. (CSB Rom. 12:1–2)
B. The “Obedience” of Faith
“ὑπακοὴν πίστεως has been variously understood as meaning: (i) ‘obedience to the faith’ (i.e., to faith in the sense of fides quae creditor, the body of doctrine accepted); (ii) ‘obedience to faith’ (i.e., to the authority of faith); (iii) ‘obedience to God’s faithfulness attested in the gospel’;
(iv) ‘the obedience which faith works’; (v) ‘the obedience required by faith’; (vi) ‘believing obedience’; (vii) ‘the obedience which consists in faith’.” (C. E. B. Cranfield, Romans, ICC [London: T&T Clark, 2004], 66)
“The verb ὑπακούω still displays its derivation from ἀκούω, ‘hear’ (see LSJ, ὑπακούω—range of meaning includes ‘give ear to, answer, heed’; LXX uses ὑπακούω to translate שָׁ מַ ע, ‘hear’); so what is envisaged primarily is response to a spoken word.” (James D. G. Dunn, Romans 1–8, WBC [Dallas: Word, 1988], 17)
I have written to remind you more boldly on some points because of the grace given me by God 16 to be a minister of Christ Jesus to the Gentiles, serving as a priest of the gospel of God. My purpose is that the Gentiles may be an acceptable offering, sanctified by the Holy Spirit… 18 For I would not dare say anything except what Christ has accomplished through me by word and deed for the obedience of the Gentiles, 19 by the power of miraculous signs and wonders, and by the power of God’s Spirit. (CSB Rom. 15:15–19)
C. Among All the Gentiles
“ἐν πᾶσιν τοῖς ἔθνεσιν, ‘among all the nations.’ (τὰ) ἔθνη certainly means ‘the Gentiles’ (and not ‘the nations’ including Jews); it is used in the LXX to translate גּוֹיִם, usually = other/foreign nations; and in Greek usage it also usually denotes foreigners.” (Dunn, Romans 1–8, 18)
For they themselves report concerning us the kind of reception we had among you, and how you turned to God from idols to serve the living and true God, 10 and to wait for his Son from heaven, whom he raised from the dead, Jesus who delivers us from the wrath to come. (ESV 1 Thess. 1:9–10)
