Matthew 24:30-33

Then the sign announcing the Son of Man will appear in the sky, and all the nations of the earth will mourn over him. And they will see the Son of Man appearing in the clouds of heaven, revealed with mighty power, great splendor, and glory. And he will send his messengers with the loud blast of the trumpet, and with a great voice they will gather his beloved chosen ones from the four winds, from one end of heaven to the other!” “Now learn the lesson from the parable of the fig tree. When spring arrives and it sends out its tender branches and sprouts leaves, you know that summer is near. So it will be with you, for when you observe all these things taking place, you will know that he is near, even at the door!
