Mark 13:24-31

²⁴"But in those days, after that tribulation, the sun will be darkened, and the moon will not give its light, ²⁵and the stars will be falling from heaven, and the powers in the heavens will be shaken. ²⁶And then they will see the Son of man coming in clouds with great power and glory. ²⁷And 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.

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. ²⁹So also, when you see these things taking place, you know that he is near, at the very gates. ³⁰Truly, I say to you, this generation will not pass away before all these things take place. ³¹Heaven and earth will pass away, but my words will not pass away.
