Q&A: Why did Jesus refer to Himself as "Son of Man"?
A: Jesus referred to Himself as the Son of Man for two main reasons:
1. As "the Son of Man" He came to represent mankind and to undo the failure of our first representative — namely, Adam.
2. Our Lord also used the term Son of Man because it was a title used of Him in the book of Daniel chapter 7. That passage says:"
"I saw in the night visions, and behold, with the clouds of heaven there came one like a son of man, and he came to the Ancient of Days and was presented before him. And 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 one that shall not be destroyed." Daniel 7:13–14 (ESV)
By referring to Himself as "Son of Man" Jesus was identifying with that prophetic passage to show that He was the one Daniel saw in his vision and wrote about.
