1 Peter 2:19 New English Translation

¹⁹For this finds God’s favor,^[a] if because of conscience toward God^[b] someone endures hardships in suffering unjustly.

1 Peter 2:19 tn Grk “For this [is] favor/grace,” used as a metonymy of that which pleases him, which he looks on with favor (cf. BDAG 1079 s.v. χάρις 2). Cf. 1 Pet 2:20.
1 Peter 2:19 tc The expression “consciousness/conscience of God” (συνείδησιν θεοῦ; suneidēsin theou) is unusual, occurring only here in the NT. Because θεοῦ was liable to misinterpretation, several witnesses altered the text, either replacing it with ἀγαθήν (agathēn; C Ψ 323 442 614 630 945 1175 1241 1243 1505 1611 1739 1852 2492 sy) or expanding the expression by adding ἀγαθήν before θεοῦ (P⁷² [A* 33 2344] 81). Replacing θεοῦ with ἀγαθήν conforms to other NT phrases, notably in this same letter (Acts 23:1; 1 Tim 1:5, 19; 1 Pet 3:16, 21), suggesting that such a reading is motivated. The reading θεοῦ, however, has superior support (א A^c B P 049 5 436 1735 M lat co), and best explains the rise of the others.tn Grk “conscious(ness) of God,” an awareness of God and allegiance to him.
