We hear precious little from 2 Peter in the lectionary. This last Sunday we heard from chapter 3, but missed these opening verses:
This is now, beloved, the second letter I am writing to you; in them I am trying to arouse your sincere intention by reminding you 2that you should remember the words spoken in the past by the holy prophets, and the commandment of the Lord and Savior spoken through your apostles. 3First of all you must understand this, that in the last days scoffers will come, scoffing and indulging their own lusts 4and saying, ‘Where is the promise of his coming? For ever since our ancestors died, all things continue as they were from the beginning of creation!’ 5They deliberately ignore this fact, that by the word of God heavens existed long ago and an earth was formed out of water and by means of water, 6through which the world of that time was deluged with water and perished. 7But by the same word the present heavens and earth have been reserved for fire, being kept until the day of judgement and destruction of the godless.
The promised day of scoffers has come (and has been around since Peter was writing, truth be told!). But God's promise is still true, and Jesus is still coming to redeem and restore all things! The fire of the end is not about destruction only, but also about refining and renewing you and me and all things.
Of course, verse five is just an odd cosmological tidbit. The heavens existed long before us, and our world was formed out of water (notice Genesis 1.1 - "God's spirit moved over the waters..."). God's Word has always been calling new creation forth into being and is not done yet!
