Peter says that this is his second letter, and that in both he aims to stir up his readers so that they remember the words of the holy prophets and the commandment of the Lord given through the apostles (vv. 1-2).
In the last days scoffers will come, following their own passions, and ask: Where is the promise of his coming? Since the fathers fell asleep, they say, all things continue as they were from creation. But they deliberately overlook that by the word of God the heavens and earth came to be, and that by that same word the world of that time was destroyed by water. The present heavens and earth are stored up by the same word for fire, kept for the day of judgment and destruction of the ungodly (vv. 3-7).
Peter asks them not to forget that with the Lord one day is as a thousand years, and a thousand years as one day. The Lord is not slow to fulfill his promise, as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance. The day of the Lord will come like a thief; the heavens will pass away with a roar, the heavenly bodies will be dissolved with fire and the earth and the works done on it will be exposed (vv. 8-10).
Since all this will be dissolved, how should they live? In holiness and godliness, hastening the day of God. Believers wait, according to his promise, for new heavens and a new earth in which righteousness dwells. So they should strive to be found without spot, at peace with him, and count the Lord's patience as salvation. Paul wrote the same, though there are things hard to understand that the ignorant twist, as they do the other Scriptures. Peter warns them not to be carried away by error and urges them to grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the glory now and to the day of eternity. Amen (vv. 11-18).
