Discovery Box2 Peter 1:3 
Context1:3 I can pray this because his divine power 1 has bestowed on us everything necessary 2 for life and godliness through the rich knowledge 3 of the one who called 4 us by 5 his own glory and excellence.
2 Peter 2:20
Context2:20 For if after they have escaped the filthy things 6 of the world through the rich knowledge of our Lord and Savior Jesus Christ, 7 they 8 again get entangled in them and succumb to them, 9 their last state has become worse for them than their first.
1 tn The verse in Greek starts out with ὡς (Jws) followed by a genitive absolute construction, dependent on the main verb in v. 2. Together, they form a subordinate causal clause. A more literal rendering would be “because his divine power…” The idea is that the basis or authority for the author’s prayer in v. 2 (that grace and peace would abound to the readers) was that God’s power was manifested in their midst. The author’s sentence structure is cumbersome even in Greek; hence, the translation has broken this up into two sentences.
2 tn The word “necessary” is not in the Greek, but is implied by the preposition πρός (pros).
3 tn See the note on “rich knowledge” in v. 2.
4 sn Called. The term καλέω (kalew), used here in its participial form, in soteriological contexts when God is the subject, always carries the nuance of effectual calling. That is, the one who is called is not just invited to be saved – he is also and always saved (cf. Rom 8:30). Calling takes place at the moment of conversion, while election takes place in eternity past (cf. Eph 1:4).
5 tn The datives ἰδίᾳ δόξῃ καὶ ἀρετῇ (idia doxh kai areth) 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 important witnesses (διὰ δόξης καὶ ἀρετῆς in Ì72 B 0209vid) 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).
6 tn Grk “defilements”; “contaminations”; “pollutions.”
7 sn Through the rich knowledge of our Lord and Savior Jesus Christ. The implication is not that these people necessarily knew the Lord (in the sense of being saved), but that they were in the circle of those who had embraced Christ as Lord and Savior.
8 tn Grk “(and/but) they.”
9 tn Grk “they again, after becoming entangled in them, are overcome by them.”
