The Son of Man, Jesus, will come with the clouds of heaven, THEN He will sit on His glorious throne!
Daniel 7: 13-14
13 “I kept looking in the night visions,
And behold, with the clouds of heaven
One like a son of man was coming,
And He came up to the Ancient of Days
And was presented before Him.
14 And to Him was given dominion,
Honor, and a kingdom,
So that all the peoples, nations, and populations of all languages
Might serve Him.
His dominion is an everlasting dominion
Which will not pass away;
And His kingdom is one
Which will not be destroyed.
