2 Peter 3:1-2
Context3:1 Dear friends, this is already the second letter I have written 6 you, in which 7 I am trying to stir up 8 your pure mind by way of reminder: 3:2 I want you to recall 9 both 10 the predictions 11 foretold by the holy prophets and the commandment of the Lord and Savior through your apostles. 12
1 tn Grk “brothers,” but the Greek word may be used for “brothers and sisters” or “fellow Christians” as here (cf. BDAG 18 s.v. ἀδελφός 1., where considerable nonbiblical evidence for the plural ἀδελφοί [adelfoi] meaning “brothers and sisters” is cited).
2 tn Grk “make your calling and election sure.”
sn Make sure of your calling and election. The author is not saying that virtue and holiness produce salvation, but that virtue and holiness are the evidence of salvation.
3 tn Grk “these things.”
4 tn In Greek οὐ μή (ou mh) followed by the subjunctive is normally the strongest way to negate an action. Coupled with πότε (pote, “ever”), the statement is even more emphatic. The author is offering sage advice on how to grow in grace.
5 tn The words “into sin” are not in the Greek text, but the Greek word πταίω (ptaiw) is used in soteriological contexts for more than a mere hesitation or stumbling. BDAG 894 s.v. 2 suggests that here it means “be ruined, be lost,” referring to loss of salvation, while also acknowledging that the meaning “to make a mistake, go astray, sin” is plausible in this context. Alternatively, the idea of πταίω here could be that of “suffer misfortune” (so K. L. Schmidt, TDNT 6:884), as a result of sinning.
6 tn Grk “I am already writing this [as] a second letter.” The object-complement construction is more smoothly rendered in English a bit differently. Further, although the present tense γράφω (grafw) is used here, English convention employs an epistolary past tense. (The Greek epistolary aorist might have been expected here, but it also occurs in situations unlike its English counterparts.)
7 tn The relative pronoun is plural, indicating that the following statement is true about both letters.
8 tn Or “I have stirred up, aroused.” The translation treats the present tense verb as a conative present.
9 tn Grk “to remember.” “I want you” is supplied to smooth out the English. The Greek infinitive is subordinate to the previous clause.
10 tn “Both” is not in Greek; it is supplied to show more clearly that there are two objects of the infinitive “to remember” – predictions and commandment.
11 tn Grk “words.” In conjunction with πρόειπον (proeipon), however, the meaning of the construction is that the prophets uttered prophecies.
12 sn Holy prophets…apostles. The first chapter demonstrated that the OT prophets were trustworthy guides (1:19-21) and that the NT apostles were also authoritative (1:16-18). Now, using the same catch phrase found in the Greek text of 1:20 (τοῦτο πρῶτον γινώσκοντες, touto prwton ginwskontes), Peter points to specific prophecies of the prophets as an argument against the false teachers.
