1 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.
2 tc The expression “consciousness/conscience of God” (συνείδησιν θεοῦ; suneidhsin qeou) is unusual, occurring only here in the NT. Because θεοῦ was liable to misinterpretation, several witnesses altered the text, either replacing it with ἀγαθήν (agaqhn; C Ψ 323 614 630 945 1241 1505 1739 al sy) or expanding the expression by adding ἀγαθήν before θεοῦ (Ì72 [A* 33] 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 Ac B P 049 Ï lat co), and best explains the rise of the other readings.
3 tn Grk “where will he appear.”
4 tn The personal references in v. 18 are generic singulars, but they have been changed to the plural in English to maintain consistency with the plurals of v. 17.
