Mark 13:24-27
The time when the Son of Man returns
24 Then, after all these bad things have happened, the sun will become dark. The moon will not shine any more. 25 Stars will fall out of the sky. And the powerful things in the sky will shake.
26 Then people will see the Son of Man. He will come in the clouds. He will have great power and bright glory. 27 Then he will send his angels. They will go in every direction, to every part of the earth and to every part of the sky. They will bring together all the people that God has chosen.
