Another remarkable feature of this chapter is that the author presupposes that his audience is familiar with a plurality of apostles ("how many" is unclear), and, moreover, that they have had (and perhaps still have) access to the teaching of these apostles. One cannot "remember" teaching that they have not received. Of course, this raises difficult questions about the precise medium (oral or written) by which the public received this apostolic teaching. However, near the end of this chapter, the means by which the audience at least received the apostle Paul teaching is expressly stated. We are told that the audience knew the teachings of "our beloved brother Paul" (3:15) and that they knew them in written form: "Paul also wrote to you according to wisdom as he does in all his letters" (3:16), the "also" being the key word since in the first verse of the chapter the author referred to another written apostolic text, namely his first epistle (1 Peter): considering part of the "Scriptures" not only the OT prophets, but also Paul and the author himself, from the Pauline corpus the author may have known 1 and 2 Thessalonians, Romans, Galatians, and possibly Ephesians and Colossians. Thought on Christian revelation is also located in other early authors, namely Clement of Rome, Ignatius, Polycarp, Justin Martyr, and in the work 2 Clement. In the middle of the chapter is the explanation for the delay in Jesus' return (3:9); Jesus' delay is only to facilitate the salvation of the "already faithful" who may at times waver in their faith or have been led astray by false teachers (2:2–3). God is delaying to make sure that "all" have had sufficient time to secure their commitment (or return) to the gospel, including the false teachers. The remaining verses provide details about the coming day of the Lord along with the exhortation that flows seamlessly into the conclusion of the letter. The instruction offered here (3:11–13) echoes that of Jesus who called his disciples to await the consummation of his kingdom with attention, service and perseverance (Mt 24-25; Mk 13:3–13, 32–37; Lk 18:1–30; 21:1–38). Taken together with the final verses (3:14–18), here again the author expresses the concern that believers secure their eternal place in God's new creation by embracing lives that foster blessing and even hasten God's coming day. quotes . quotes Psalm 90, specifically .
