Mark 13:24-37
13:24 "But in those days, after that suffering, the sun will be darkened, and the moon will not give its light,
13:25 and the stars will be falling from heaven, and the powers in the heavens will be shaken.
13:26 Then they will see 'the Son of Man coming in clouds' with great power and glory.
13:27 Then he will send out the angels, and gather his elect from the four winds, from the ends of the earth to the ends of heaven.
13:28 "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.
13:29 So also, when you see these things taking place, you know that he is near, at the very gates.
13:30 Truly I tell you, this generation will not pass away until all these things have taken place.
13:31 Heaven and earth will pass away, but my words will not pass away.
13:32 "But about that day or hour no one knows, neither the angels in heaven, nor the Son, but only the Father.
13:33 Beware, keep alert; for you do not know when the time will come.
13:34 It is like a man going on a journey, when he leaves home and puts his slaves in charge, each with his work, and commands the doorkeeper to be on the watch.
13:35 Therefore, keep awake--for you do not know when the master of the house will come, in the evening, or at midnight, or at cockcrow, or at dawn,
13:36 or else he may find you asleep when he comes suddenly.
13:37 And what I say to you I say to all: Keep awake."
