Matthew 24:30-36

30“Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory. 31And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other. 32“Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. 33Even so, when you see all these things, you know that it is near, right at the door. 34Truly I tell you, this generation will certainly not pass away until all these things have happened. 35Heaven and earth will pass away, but my words will never pass away. 36“But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.
