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 “dear friends, waiting for.” See note in v. 13 on “waiting for.”

⁷ sn The Greek verb used in the phrase strive to be found is the same as is found in v. 10, translated “laid bare.” In typical Petrine fashion, a conceptual link is made by the same linkage of terms. The point of these two verses thus becomes clear: When the heavens disappear and the earth and its inhabitants are stripped bare before the throne of God, they should strive to make sure that their lives are pure and that they have nothing to hide.

⁸ tn “When you come into” is not in Greek. However, the dative pronoun αὐτῷ (autw) does not indicate agency (“by him”), but presence or sphere. The idea is “strive to found {before him/in his presence}.”
