[23] The final five verses of the epistle contain the concluding part (peroratio) of the discourse, starting with the phrase: "Therefore, beloved" (verse 14, and used again in verse 17) and continue with a tone similar to the opening in the first chapter, echoing the 2 Peter 1:1–2 ('grace, knowledge, and Jesus as Savior') with the final words ('day of eternity') as the last reminder of this epistle's major theme, that is, 'the judgment day will come'.
