Jesus Christ is THE CREATOR In Isaiah

[Runningman]

Isaiah wasn't there when Jesus ascended. Daniel did kind of see this.
Dan 7:13 "I was watching in the night visions, And behold, One like the Son of Man, Coming with the clouds of heaven! He came to the Ancient of Days, And they brought Him near before Him.
Dan 7:14 Then to Him was given dominion and glory and a kingdom, That all peoples, nations, and languages should serve Him. His dominion is an everlasting dominion, Which shall not pass away, And His kingdom the one Which shall not be destroyed.

But God isn't the Son of Man.

Numbers 23​

19God is not a man, that He should lie,​

or a son of man, that He should change His mind.​

Does He speak and not act?​

Does He promise and not fulfill?​

In Daniel's vision, he was in Heaven and saw Jesus coming up (ascending) with clouds. The disciples standing on the ground saw Jesus ascend and a cloud blocked their vision. Along with verse 14 above, at the end of Matthew the disciples see Jesus later and He says:
Mat 28:18 And Jesus came and spoke to them, saying, "All authority has been given to Me in heaven and on earth.

Jesus didn't ascend on his own power to heaven. He was carried up into heaven by God.

Luke 24​

51While He was blessing them, He left them and was carried up into heaven.​
