When the Son of Man, Jesus, comes he will be seen by everyone, like lightening flashing from the east to the west. Soon after the trouble of those days, the sun will grow dark, and the moon will not give its light. The stars will fall from the sky. And the powers of the heavens will be shaken. At that time, the sign of the Son of Man will appear in the sky. Then all the peoples of the world will cry. They will see the Son of Man coming on clouds in the sky with great power and glory! He will use a loud trumpet to send his angels all around the earth, and they will gather his chosen people from every part of the world. Matthew 24:27,29-31
