Mark 13:32-37; 2 Peter 3:8-15
"However, no one knows the day or hour when these things will happen, not even the angels in heaven or the Son himself. Only the Father knows.
And since you don't know when they will happen, stay alert and keep watch.
"The coming of the Son of Man can be compared with that of a man who left home to go on a trip. He gave each of his employees instructions about the work they were to do, and he told the gatekeeper to watch for his return.
So keep a sharp lookout! For you do not know when the homeowner will return -- at evening, midnight, early dawn, or late daybreak.
Don't let him find you sleeping when he arrives without warning.
What I say to you I say to everyone: Watch for his return!"
But you must not forget, dear friends, that a day is like a thousand years to the Lord, and a thousand years is like a day.
The Lord isn't really being slow about his promise to return, as some people think. No, he is being patient for your sake. He does not want anyone to perish, so he is giving more time for everyone to repent.
But the day of the Lord will come as unexpectedly as a thief. Then the heavens will pass away with a terrible noise, and everything in them will disappear in fire, and the earth and everything on it will be exposed to judgment.
Since everything around us is going to melt away, what holy, godly lives you should be living!
You should look forward to that day and hurry it along -- the day when God will set the heavens on fire and the elements will melt away in the flames.
But we are looking forward to the new heavens and new earth he has promised, a world where everyone is right with God.
And so, dear friends, while you are waiting for these things to happen, make every effort to live a pure and blameless life. And be at peace with God.
And remember, the Lord is waiting so that people have time to be saved. This is just as our beloved brother Paul wrote to you with the wisdom God gave him --
