?Therefore keep watch, because you do not know on what day your Lord will come. 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.? (Matt. 24:42-44)
"Now, brothers, 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, are not in darkness so that this day should surprise you like a thief." (1 Thes. 5:1-4)
"Remember, therefore, what you have received and heard; obey it, and repent. But if you do not wake up, I will come like a thief, and you will not know at what time I will come to you." (Rev. 3:3)
?Behold, I come like a thief! Blessed is he who stays awake and keeps his clothes with him, so that he may not go naked and be shamefully exposed.? (Rev. 16:15)
"I do not want you to be ignorant of this mystery, brothers, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in." (Romans 11:25)
"When you see Jerusalem surrounded by armies, then know that its desolation has come near...Jerusalem will be trampled on by the Gentiles, until the times of the Gentiles are fulfilled....Then they will see ?the Son of Man coming in a cloud? with power and great glory. Now when these things begin to take place, stand up and raise your heads, because your redemption is drawing near." Then he told them a parable: "Look at the fig tree and all the trees; as soon as they sprout leaves you can see for yourselves and know that summer is already near. So also, when you see these things taking place, you know that the kingdom of God is near. Truly I tell you, this generation will not pass away until all things have taken place." Luke 21:5-36, Exerpts.
