Mark 13:32-37; 2 Peter 3:8-15

32 “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. 33 And since you don’t know when that time will come, be on guard! Stay alert ! 34 “The coming of the Son of Man can be illustrated by the story of a man going on a long trip. When he left home, he gave each of his slaves instructions about the work they were to do, and he told the gatekeeper to watch for his return. 35 You, too, must keep watch! For you don’t know when the master of the household will return—in the evening, at midnight, before dawn, or at daybreak. 36 Don’t let him find you sleeping when he arrives without warning. 37 I say to you what I say to everyone: Watch for him!”
8 But you must not forget this one thing, dear friends: A day is like a thousand years to the Lord, and a thousand years is like a day. 9 The Lord isn’t really being slow about his promise, as some people think. No, he is being patient for your sake. He does not want anyone to be destroyed, but wants everyone to repent. 10 But the day of the Lord will come as unexpectedly as a thief. Then the heavens will pass away with a terrible noise, and the very elements themselves will disappear in fire, and the earth and everything on it will be found to deserve judgment. 11 Since everything around us is going to be destroyed like this, what holy and godly lives you should live, 12 looking forward to the day of God and hurrying it along. On that day, he will set the heavens on fire, and the elements will melt away in the flames. 13 But we are looking forward to the new heavens and new earth he has promised, a world filled with God’s righteousness. 14 And so, dear friends, while you are waiting for these things to happen, make every effort to be found living peaceful lives that are pure and blameless in his sight. 15 And remember, our Lord’s patience gives people time to be saved. This is what our beloved brother Paul also wrote to you with the wisdom God gave him—
