Re: Daniel's prophecy at Daniel 7:13-14 and?

The Ancient of Days is God the Father. The "son of man" was a title the Lord Jesus used of Himself many times. Most scholars think that He used that title "son of man" as a reference to this page that you have posted. They are "one" in unity and essence, yet the mystery of God is that while there is only One God, He has revealed Himself to humanity in 3 "persons".
