¹ tn The ἵνα (hina) clause in 4:21 could be giving (1) the purpose or (2) the result of the commandment mentioned in the first half of the verse, but if it does, the author nowhere specifies what the commandment consists of. It makes better sense to understand this ἵνα clause as (3) epexegetical to the pronoun ταύτην (tautēn) at the beginning of 4:21 and thus explaining what the commandment consists of: “that the one who loves God should love his brother also.”

³ tn Grk “that one” (a reference to Jesus is indicated in the context). Once more the author uses the pronoun ἐκεῖνος (ekeinos) to refer to Jesus Christ, as he did in 2:6; 3:3, 5, 7, and 16. A reference to Christ is confirmed in this context because the author says that “just as he is, so also are we [believers] in this world” and since 3:2 indicated that believers are to be like God in the future (but are not yet), the only one believers can be like already in the present age is Jesus Christ.

² tn This verse begins with the phrase καὶ αὕτη ἐστίν (kai hautē estin; cf. the similar phrase in 3:11 and 1:5), which is explained by the following ἵνα (hina) clause, “that we believe in the name of his Son Jesus Christ.” The ἵνα thus introduces a clause which is (1) epexegetical (explanatory) or (2) appositional. By analogy the similar phrase in 3:11 is also followed by an epexegetical ἵνα clause and the phrase in 1:5 by an epexegetical ὅτι (hoti) clause.

¹ tc The Byzantine text, with a handful of other mss (81 642 1175 2492 M), lacks the last eight words of this verse, “The person who confesses the Son has the Father also” (ὁ ὁμολογῶν τὸν υἱὸν καὶ τὸν πατέρα ἔχει, ho homologōn ton huion kai ton patera echei). Although shorter readings are often preferred (since scribes would tend to add material rather than delete it), if an unintentional error is likely, shorter readings are generally considered secondary. This is a classic example of such an unintentional omission: The τὸν πατέρα ἔχει of the preceding clause occasioned the haplography, with the scribe’s eye skipping from one τὸν πατέρα ἔχει to the other.

² sn Critics generally assume that 2 Peter is not authentic, partially because in vv. 15-16 Paul is said to have written scripture. It is assumed that a recognition of Paul’s writings as scripture could not have happened until early in the 2nd century. However, in the same breath that Paul is canonized, Peter also calls him “brother.” This is unparalleled in the 2nd century apocryphal works, as well as early patristic writings, in which the apostles are universally elevated above the author and readers; here, Peter simply says “he’s one of us.”

¹ tn Grk “knowing this [to be] foremost.” Τοῦτο πρῶτον (touto prōton) constitute the object and complement of γινώσκοντες (ginōskontes). The participle is loosely dependent on the infinitive in v. 2 (“[I want you] to recall”), perhaps in a telic sense (thus, “[I want you] to recall…[and especially] to understand this as foremost”). The following statement then would constitute the main predictions with which the author was presently concerned. An alternative is to take it imperativally: “Above all, know this.” In this instance, however, there is little semantic difference (since a telic participle and imperatival participle end up urging an action). Cf. also 2 Pet 1:20.

⁵ tn The words “into sin” are not in the Greek text, but the Greek word πταίω (ptaiō) 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.

⁵ tn The datives ἰδίᾳ δόξῃ καὶ ἀρετῇ (idia doxē kai aretē) could be taken either instrumentally (“by [means of] his own glory and excellence”) or advantage (“for [the benefit of] his own glory and excellence”). Both the connection with divine power and the textual variant found in several early and significant witnesses (διὰ δόξης καὶ ἀρετῆς in P⁷² B 0209^vid) argues for an instrumental meaning. The instrumental notion is also affirmed by the meaning of ἀρετῇ (“excellence”) in contexts that speak of God’s attributes (BDAG 130 s.v. ἀρετή 2 in fact defines it as “manifestation of divine power” in this verse).

⁴ tn Or “when he visits.” Grk “in the day of visitation,” denoting a time when God intervenes directly in human affairs, either for blessing (Luke 1:68, 78; 7:16; 19:44) or for judgment (Isa 10:3; Jer 6:15). This phrase may be a quotation from Isa 10:3, in which case judgment is in view here. But blessing seems to be the point, since part of the motive for good behavior is winning the non-Christian over to the faith (as in 3:1; also apparently in 3:15; cf. Matt 5:16).

¹ sn If we are unfaithful…he cannot deny himself. This could be (1) a word of warning (The Lord will exact punishment; he cannot deny his holiness) or (2) a word of hope (Because of who he is, he remains faithful to us despite our lapses). The latter is more likely, since Paul consistently cites God’s faithfulness as a reassurance, not as a warning (cf. especially Rom 3:3; also 1 Cor 1:9; 10:13; 2 Cor 1:18; 1 Thess 5:24; 2 Thess 3:3).

¹ tn Grk “those of the circumcision.” The verse as a whole is difficult to translate because it is unclear whether Paul is saying (1) that the only people working with him are Jewish converts at the time the letter is being written or previously, or (2) that Aristarchus, Mark, and Jesus Justus were the only Jewish Christians who ever worked with him. Verses 12-14 appear to indicate that Luke and Demas, who were Gentiles, were also working currently with Paul. This is the view adopted in the translation. See M. J. Harris, Colossians and Philemon (EGGNT), 207-8.

⁶ sn The ruler of the kingdom of the air is also the ruler of the spirit that is now energizing the sons of disobedience. Although several translations regard the ruler to be the same as the spirit, this is unlikely since the cases in Greek are different (ruler is accusative and spirit is genitive). To get around this, some have suggested that the genitive for spirit is a genitive of apposition. However, the semantics of the genitive of apposition are against such an interpretation (cf. ExSyn 100).

³ tn Or “This power he exercised in Christ by raising him”; Grk “raising him.” The adverbial participle ἐγείρας (egeiras) could be understood as temporal (“when he raised [him]”), which would be contemporaneous to the action of the finite verb “he exercised” earlier in the verse, or as means (“by raising [him]”). The participle has been translated here with the temporal nuance to allow for means to also be a possible interpretation. If the translation focused instead upon means, the temporal nuance would be lost as the time frame for the action of the participle would become indistinct.

¹ sn Down payment. The Greek word ἀρραβών (arrabōn) denotes the first payment or first installment of money or goods which serves as a guarantee or pledge for the completion of the transaction. In the NT the term is used only figuratively of the Holy Spirit as the down payment of the blessings promised by God (it is used also in 2 Cor 1:22 and 5:5). In the “already—not yet” scheme of the NT the possession of the Spirit now by believers (“already”) can be viewed as a guarantee that God will give them the balance of the promised blessings in the future (“not yet”).

¹ tn Or “He did this by revealing”; Grk “making known, revealing.” Verse 9 begins with a participle dependent on “lavished” in v. 8; the adverbial participle could be understood as temporal (“when he revealed”), which would be contemporaneous to the action of the finite verb “lavished,” or as means (“by revealing”). The participle has been translated here with the temporal nuance to allow for means to also be a possible interpretation. If the translation focused instead upon means, the temporal nuance would be lost as the time frame for the action of the participle would become indistinct.

³ tc The majority of later mss (א² A^c D¹ Ψ 0243 0278 33 1739 1881 M) as well as some versional witnesses include the pronoun “my” here, but the omission of the pronoun has excellent external support (P^46vid א* A* B D* F G latt). Scribes probably added the pronoun for clarity, making the obvious referent explicit. This would also make “power” more parallel with “my grace.” Though the original text probably did not include “my,” scribes who added the word were following the sense of Paul’s statement.

² sn I will live in them. The OT text that lies behind this passage (Lev 26:11-12) speaks of God dwelling in the midst of his people. The Greek preposition en in the phrase en autois (“in them”) can also have that meaning (“among” or “with”). However, Paul appears to be extending the imagery here to involve God (as the Spirit) dwelling in his people, since he calls believers “the temple of the living God” in the previous clause, imagery he uses elsewhere in his writings (1 Cor 3:16; Eph 2:21-22).

¹ sn Down payment. The Greek word ἀρραβών (arrabōn) denotes the first payment or first installment of money or goods which serves as a guarantee or pledge for the completion of the transaction. In the NT the term is used only figuratively of the Holy Spirit as the down payment of the blessings promised by God (it occurs later in 2 Cor 5:5, and also in Eph 1:14). In the “already—not yet” scheme of the NT the possession of the Spirit now by believers (“already”) can be viewed as a guarantee that God will give them the balance of the promised blessings in the future (“not yet”).

¹ tc Grk “the brother.” Later witnesses (א² D² M) have ἀνδρί (andri, “husband”) here, apparently in conscious emulation of the earlier mention of ἀνήρ (anēr) in the verse. However, the earliest and best witnesses (P⁴⁶ א* A B C D* F G P Ψ 33 1739 al co) are decisively in favor of ἀδελφῷ (adelphō, “brother”), a word that because of the close association with “wife” here may have seemed inappropriate to many scribes. It is also for reasons of English style that “her husband” is used in the translation.

² tc Most mss (א¹ A D¹ Ψ 33 1175 1241 1505 1881 2464 M sy) have θεοῦ (theou) here rather than Χριστοῦ (Christou; found in א* B C D* 6 81 629 1506 1739 lat co). Although the Nestle-Aland apparatus includes P^46vid for this reading, more recent photographs by CSNTM reveal it to be κυρίου (“Lord”), a singular reading. External evidence strongly favors the reading “Christ” here. Internal evidence is also on its side, for the expression ῥῆμα Χριστοῦ (rhēma Christou) occurs nowhere else in the NT; thus scribes would be prone to change it to a known expression.
