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).
1 Remind them to be subject to rulers and authorities, to obey, to be ready for every good work, 2 to speak evil of no one, to be peaceable, gentle, showing all humility to all men. 3 For we ourselves were also once foolish, disobedient, deceived, serving various lusts and pleasures, living in malice and envy, hateful and hating one another.” (Titus 3:1–3, NKJV)
Reminders. We all need them. They reinforce what we already know, encouraging us to persevere, to be on guard, and to grow spiritually. Paul had just exhorted Titus to “speak the things which are proper for sound doctrine” (Titus 2:1). Now he teaches him to remind Christians of sound attitudes and actions of faith. 1) We must remember to be submissive (v. 1-2). Obeying civil authority reflects the submissive lifestyle of the saint, equipping us for good works that cannot be successfully condemned (cf. Titus 2:8; 1 Pet. 2:11-12). Being submissive requires “showing humility to all men.” It takes moral strength to be humble, to be peaceable and gentle instead of speaking evil of others. 2) We must remember we once lived in sin (v. 3). Our salvation in Christ is not a license to be dismissive or condescending toward those who are still captives of sin. Recalling our previous sins (and forgiveness in Christ) is an incentive to remain vigilant in faith and responsive to help others escape evil. Do not be drawn back into foolish disobedience and selfish desires. The love of God in Christ compels us to be kind and careful to maintain good works that honor God and serve others (Titus 3:4, 8).
12 For this reason I will not be negligent to remind you always of these things, though you know and are established in the present truth. 13 Yes, I think it is right, as long as I am in this tent, to stir you up by reminding you, 14 knowing that shortly I must put off my tent, just as our Lord Jesus Christ showed me. 15 Moreover I will be careful to ensure that you always have a reminder of these things after my decease. (2 Peter 1:12–15, NKJV)
One of Peter’s goals in 2 Peter was to remind his fellow Christians they partook of the divine nature through “exceedingly great and precious promises” as they diligently made their “call and election sure” through spiritual growth and fruitfulness (2 Pet. 1:2-10). By doing so, they would enter the everlasting kingdom (2 Pet. 1:11). Note that Peter was not telling them a new message. They knew the “present truth” and were firm in it. He reminded them of these great truths so that after his death, they would continue to remember them and remain faithful. Teaching the gospel is not about hearing and telling some new thing like the Athenian philosophers (Acts 17:21). It is about telling “the old, old story” to each generation with repetition, clarity, and resolve. Like Peter, this present generation will die. May we continue to secure and arouse faith in our generation and the next by preaching the gospel truth that abides forever (1 Pet. 1:22-25).
But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe. (Jude 5, NKJV)
Christians need to be continually reminded of the truth we have known (2 Pet. 1:12). Being reminded of the truth we once knew” is a prevention against falling away. Yes indeed, God’s people can fall away. Among God’s people Israel, those who “did not believe” were “destroyed” in the wilderness (Heb. 3:7-11). Although God had saved them out of Egyptian bondage, when they “rebelled,” “sinned,” “did not obey,” they not enter the land of promise due to their “unbelief” (Heb. 3:16-19). Jude uses Israel’s apostasy to warn faithful brethren of false teachers (Jude 3-4, 8). You see, it matters to God what Christians believe and the teachings we accept. False teaching produces false faith. Although we have been saved from the bondage of sin, if we do not faithfully continue in “the faith,” then we become like the wilderness Israelites. And like them, we will be destroyed because of our unbelief.
