Mark 13:31-37

31 Earth and sky will pass away, but it is certain that my words will not pass away.

32 "But as to that day or the exact time no one knows--not even the angels in Heaven, nor the Son, but the Father alone.

33 Take care, be on the alert, and pray; for you do not know when it will happen.

34 It is like a man living abroad who has left his house, and given the management to his servants--to each one his special duty--and has ordered the porter to keep awake.

35 Be wakeful therefore, for you know not when the master of the house is coming--in the evening, at midnight, at cock-crow, or at dawn.

36 Beware lest He should arrive unexpectedly and find you asleep.

37 Moreover, what I say to you I say to all--Be wakeful!"
