1 Beloved, I now write to you this second epistle (in both of which I stir up your pure minds by way of reminder), 2 that you may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us, the apostles of the Lord and Savior (2 Peter 3:1–2, NKJV).
We need reminders. Calendars help us remember the day and its events. From a string around the finger, post-it notes, or an alarm clock, we need help remembering important events. God knows this, too. He inspired Peter and others to write letters that stimulate our understanding and remind us of the will of God. We “gird up the loins of (our) minds” as we remember the truth we know and in which we are established (1 Pet. 1:13; 2 Pet. 1:12-13). We must not forget the words spoken by the holy prophets. Their words were from God (1 Pet. 1:10-12; 2 Pet. 1:20-21). We must remember the commands of the apostles of Christ because they constitute the Savior’s will (1 Cor. 14:37). The pure (sincere) mind knows and remembers the inspired words from God. By learning and being grounded in the Scriptures of the prophets and apostles of Christ, we are equipped to (1) Identify and avoid false doctrine (2 Pet. 3:3-9), (2) Look forward to the day of the Lord in holiness and hope (2 Pet. 3:10-14), (3) Consider God’s longsuffering as securing our salvation, not abandoning us to the world (2 Pet. 3:15, 9, 3-4), (4) Handle God’s word properly to avoid falling into destruction (2 Pet. 3:16-17), and (5) Grow in the grace and knowledge of the Lord and Savior Jesus Christ (2 Pet. 3:18). The Scriptures stir up fervent faith as we remember them. Let us not forget God’s word nor scoff at its truth (2 Pet. 3:3-5).
