2 Peter 3:3-9
Above all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. They will say, Where is this coming he promised? Ever since our ancestors died, everything goes on as it has since the beginning of creation.....
But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.
We scoffers have been right for the past two millennia. The Bible says that no one knows the day that the Lord will come.
