Son of Man

In my vision in the night I continued to watch, and I saw One like the Son of Man coming with the clouds of heaven. He approached the Ancient of Days and was led into His presence. (Daniel 7:13 BSB)

And Jesus said, "I am, and you will see the Son of Man seated at the right hand of Power, and coming with the clouds of heaven." (Mark 14:62 ESV)

Then I looked, and there was a white cloud, and one like the Son of Man was seated on the cloud, with a golden crown on his head and a sharp sickle in his hand. (Revelation 14:14 CSB)

Unlike many religious leaders and founders of religions who popped into history without warning, the coming of Jesus was predicted in advance in the Old Testament. He came to fulfil the prophecies in the Old Testament (Psalm 40:7-8, Hebrews 10:7). He came to be King, as prophesied by Daniel. Jesus Himself also quoted Daniel's prophecy.

He is the Son of Man, who will be seated on the cloud when He comes again.

Then I saw heaven opened, and there was a white horse. Its rider is called Faithful and True, and with justice he judges and makes war. His eyes were like a fiery flame, and many crowns were on his head. He had a name written that no one knows except himself. He wore a robe dipped in blood, and his name is called the Word of God. The armies that were in heaven followed him on white horses, wearing pure white linen. A sharp sword came from his mouth, so that he might strike the nations with it. He will rule them with an iron rod. He will also trample the winepress of the fierce anger of God, the Almighty. And he has a name written on his robe and on his thigh: KING OF KINGS AND LORD OF LORDS. (Revelation 19:11-16 CSB)
