The Bible describes the events
of Jesus' return in apocalyptic
images.
Mark 13:26-27
And then they will see 'the Son of Man coming in the
clouds' with great
power and glory, and then he will
send out the angels and gather (his) elect from the
four winds, from the end of the earth to the end of the
sky.
Matthew 16:27
For the Son of Man will come with his angels in his
Father's glory, and then he will repay everyone
according to his conduct.
Acts 1:11
They (two men dressed in white) said, "Men of
Galilee,
why are you standing there looking at the sky? This
Jesus who has been taken up from you into heaven
will return in the same way as you have seen him
going into heaven."
