My dear friends, this is now my second letter to you. I have written both letters to stir up your sincere understanding with a reminder.
References for 2 Peter 3:1
I want you to recall what the holy prophets foretold as well as what the Lord and savior commanded through your apostles.
Most important, know this: in the last days scoffers will come, jeering, living by their own cravings,
and saying, "Where is the promise of his coming? After all, nothing has changed—not since the beginning of creation, nor even since the ancestors died."
But they fail to notice that, by God's word, heaven and earth were formed long ago out of water and by means of water.
And it was through these that the world of that time was flooded and destroyed.
But by the same word, heaven and earth are now held in reserve for fire, kept for the Judgment Day and destruction of ungodly people.
Don't let it escape your notice, dear friends, that with the Lord a single day is like a thousand years and a thousand years are like a single day.
The Lord isn't slow to keep his promise, as some think of slowness, but he is patient toward you, not wanting anyone to perish but all to change their hearts and lives.
But the day of the Lord will come like a thief. On that day the heavens will pass away with a dreadful noise, the elements will be consumed by fire, and the earth and all the works done on it will be exposed.
