IMHO the 'loud command' will be 'Come up here!" Why? Because...
In
Revelation 4:1, Jesus
said it when He called to John, "After this I looked, and behold, a door
standing open in heaven! And the first voice, which I had heard speaking to me
like a trumpet, said, “Come up here, and I will show you what must take place
after this.”
In
Revelation 11:12, the
Lord commands His two witnesses who had lain dead in the street of Jerusalem for
three and a half days to "come up here!"
"Then they heard a loud voice
from heaven saying to them, “Come up here!” And they went up to heaven in a
cloud, and their enemies watched them."
How exciting it will be when
Jesus calls with the voice of an archangel and a trumpet and many waters (in
other words, LOUD!) "Come up here!"
Transcending gravity, hurtling
through space in a glorified perfect body, we WILL come up there, and we will
meet our Groom.
"It will be good for those servants whose master finds
them ready, even if he comes in the second or third watch of the night."
