Look, I come like a thief! 
Matthew 24:43-44  "But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. So you also must be ready, because the Son of Man will come at an hour when you do not expect him." (see also Luke 12:39)

1 Thessalonians 5:1-6  Now, brothers and sisters, about times and dates we do not need to write to you, for you know very well that the day of the Lord will come like a thief in the night. While people are saying, "Peace and safety," destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape. But you, brothers and sisters, are not in darkness so that this day should surprise you like a thief. You are all children of the light and children of the day. We do not belong to the night or to the darkness. So then, let us not be like others, who are asleep, but let us be awake and sober. 
2 Peter 3:10  But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.

Blessed is the one who stays awake 
Luke 12:37  "It will be good for those servants whose master finds them watching when he comes. Truly I tell you, he will dress himself to serve, will have them recline at the table and will come and wait on them."
Matthew 24:42  "Therefore keep watch, because you do not know on what day your Lord will come."
Matthew 25:13  "Therefore keep watch, because you do not know the day or the hour."

and remains clothed, so as not to go naked and be shamefully exposed 
Revelation 3:18  "I counsel you to buy from me gold refined in the fire, so you can become rich; and white clothes to wear, so you can cover your shameful nakedness; and salve to put on your eyes, so you can see."
