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 “and.” The use of καί (kai) is of course quite elastic. Only the context can determine if it is adversative, continuative, transitional, etc.
7 sn We in v. 19 is apparently an inclusive “we” (the author and his audience). Such shifts in the first person plural are quite common in epistolary literature (cf., e.g., 2 Cor 10-13, passim).
8 tn The comparative adjective βεβαιότερον (bebaioteron) is the complement to the object τὸν προφητικὸν λόγον (ton profhtikon logon). As such, the construction almost surely has the force “The prophetic word is (more certain/altogether certain) – and this is something that we all have.” Many scholars prefer to read the construction as saying “we have the prophetic word made more sure,” but such a nuance is unparalleled in object-complement constructions (when the construction has this force, ποιέω [poiew] is present [as in 2 Pet 1:10]). The meaning, as construed in the translation, is that the Bible (in this case, the OT) that these believers had in their hands was a thoroughly reliable guide. Whether it was more certain than was even Peter’s experience on the Mount of Transfiguration depends on whether the adjective should be taken as a true comparative (“more certain”) or as an elative (“very certain, altogether certain”). Some would categorically object to any experience functioning as a confirmation of the scriptures and hence would tend to give the adjective a comparative force. Yet the author labors to show that his gospel is trustworthy precisely because he was an eyewitness of this great event. Further, to say that the OT scriptures (the most likely meaning of “the prophetic word”) were more trustworthy an authority than an apostle’s own experience of Christ is both to misconstrue how prophecy took place in the OT (did not the prophets have visions or other experiences?) and to deny the final revelation of God in Christ (cf. Heb 1:2). In sum, since syntactically the meaning that “we have confirmed the prophetic word by our experience” is improbable, and since contextually the meaning that “we have something that is a more reliable authority than experience, namely, the Bible” is unlikely, we are left with the meaning “we have a very reliable authority, the Old Testament, as a witness to Christ’s return.” No comparison is thus explicitly made. This fits both the context and normal syntax quite well. The introductory καί (kai) suggests that the author is adding to his argument. He makes the statement that Christ will return, and backs it up with two points: (1) Peter himself (as well as the other apostles) was an eyewitness to the Transfiguration, which is a precursor to the Parousia; and (2) the Gentile believers, who were not on the Mount of Transfiguration, nevertheless have the Old Testament, a wholly reliable authority that also promises the return of Christ.
9 tn Grk “paying attention” (the adverbial participle is either conditional [“if you pay attention”] or instrumental [“by paying attention”]; though there is difference in translation, there is virtually no difference in application). On a lexical level, “pay attention to” (προσέχω [prosecw]) does not, in a context such as this, mean merely observe or notice, but follow, give heed to, obey.
10 tn “To this” is a relative pronoun in Greek. The second half of v. 19 is thus a relative clause. Literally it reads “to which you do well if you pay attention.”
11 tn Grk “as”; ὡς (Jws) clauses after imperatives or implied commands (as here) make a comparison of what should be true (imperative) to what is true (indicative). This is the case even when the verb of the ὡς clause is only implied. Cf. Matt 6:10 (“may your will be done on earth as [it is] in heaven”); 10:16 (“be wise as serpents [are], and be as gentle as doves [are]”); 22:39 (“love your neighbor as [you already do] love yourself”).
12 sn The reference to the morning star constitutes a double entendre. First, the term was normally used to refer to Venus. But the author of course has a metaphorical meaning in mind, as is obvious from the place where the morning star is to rise – “in your hearts.” Most commentators see an allusion to Num 24:17 (“a star shall rise out of Jacob”) in Peter’s words. Early Christian exegesis saw in that passage a prophecy about Christ’s coming. Hence, in this verse Peter tells his audience to heed the OT scriptures which predict the return of Christ, then alludes to one of the passages that does this very thing, all the while running the theme of light on a parallel track. In addition, it may be significant that Peter’s choice of terms here is not the same as is found in the LXX. He has used a Hellenistic word that was sometimes used of emperors and deities, perhaps as a further polemic against the paganism of his day.
13 sn The phrase in your hearts is sometimes considered an inappropriate image for the parousia, since the coming of Christ will be visible to all. But Peter’s point has to do with full comprehension of the revelation of Christ, something only believers will experience. Further, his use of light imagery is doing double-duty, suggesting two things at once (i.e., internal guidance to truth or illumination, and OT prophecy about Christ’s return) and hence can not be expected to be consistent with every point he wishes to make.
