“From the fig tree learn its lesson: as soon as its branch becomes tender and puts forth its leaves, you know that summer is near. So also, when you see these things taking place, you know that he is near, at the very gates. Truly, I say to you, this generation will not pass away before all these things take place. Heaven and earth will pass away, but my words will not pass away.
“But of that day or that hour no one knows, not even the angels in heaven, nor the Son, but only the Father. Take heed, watch;for you do not know when the time will come. It is like a man going on a journey, when he leaves home and puts his servants in charge, each with his work, and commands the doorkeeper to be on the watch. Watch therefore””for you do not know when the master of the house will come, in the evening, or at midnight, or at cockcrow, or in the morning””lest he come suddenly and find you asleep. And what I say to you I say to all: Watch.”
–Mark 13:28-37
