2 Peter 1

The chapter functions as a circular argument moving from the divine provision of potential (vv. 3-4) to the human responsibility of actualization (vv. 5-11), finally grounding this entire movement in the objective authority of the prophetic Word (vv. 12-21).

• Those who possess and abound in these virtues shall not be barren or unfruitful (v. 8).
• Those who do these things shall never fall (v. 10).
• An abundant entrance shall be ministered into the everlasting kingdom (v. 11).

• Add to your faith virtue, and to virtue knowledge, and so on (vv. 5-7).
• Give diligence to make your calling and election sure (v. 10).
• Take heed to the more sure word of prophecy (v. 19).

• He who lacks these virtues is blind and has forgotten his purification (v. 9).

• Peter writes near the end of his life, identifying his body as a 'tabernacle' (skēnōma) that is soon to be put off, reflecting the martyrdom prophesied by Christ in John 21:18-19.
• Matthew Henry observes that faith unites the weak and strong believer equally to Christ, but warns that assurance of calling and election must be 'laboured' for through believing and well-doing.

• The term 'virtue' (ἀρέτη - arétē) was used in Greek culture to describe moral valor or excellence; Peter sanctifies this concept by anchoring it in faith rather than human philosophy.

• This chapter sets the tone for the letter, which functions largely as a warning against false teachers who will arise in the church (elaborated in chapter 2).
• The connection between the 'eyewitness' account of the Transfiguration (v. 17-18) and the 'more sure word of prophecy' (v. 19) is significant; Peter argues that written revelation is even more reliable than his own direct experience.

• The transfiguration reference links directly to Matthew 17:5, where the Father speaks, 'This is my beloved Son, in whom I am well pleased.'
• The term 'calling and election' (v. 10) connects to the broader Pauline and Petrine theology of the church as the elect of God (e.g., 1 Peter 1:1-2).

• Psalm 119:105 ('Thy word is a lamp unto my feet') provides the background imagery for Peter's description of Scripture as a 'light that shineth in a dark place' (v. 19).

• δοῦλος (doûlos) [G1401]: Used here as a slave, highlighting Peter's complete submission to Christ.
• ἐπίγνωσις (epígnōsis) [G1922]: More than mere head knowledge; it implies 'full discernment' or experiential recognition.
• ἰσότιμος (isótimos) [G2472]: 'Of equal value' or 'equal honor', emphasizing the egalitarian standing of believers in the body of Christ regardless of their background.
• ἀρέτη (arétē) [G703]: Often translated 'virtue' or 'excellence'; in the Greek world, this denoted moral courage or vigor.
• ἴδιος (ídios) [G2398]: Used in 'private interpretation' (v. 20), indicating that prophecy does not originate from the prophet's own unique, private origin or impulse.

• Modern readers often skip over the list of virtues in verses 5-7, but Peter presents them as a necessary logical chain; one cannot achieve 'charity' (agapē) without the foundational disciplines of temperance and patience.
• The emphasis on 'remembrance' (v. 12, 13, 15) shows that apostolic teaching is not about new insights, but about keeping the established truth before the church.

• Regarding 'make your calling and election sure' (v. 10): There is a significant historic interpretive tension here. Reformed positions often interpret this as the believer confirming their own assurance of salvation through the objective fruit of sanctification. Other traditions (such as Arminianism) have historically cautioned that this passage implies that one's status as 'called and elect' can be maintained or lost based on whether the believer continues to 'do these things'.
