25. The Lord is called the Son of man when the subject is judgment. This is clear from the following:

When the Son of man comes in His glory..., then He will sit on the throne of His glory. And He will set the sheep on His right, and the goats on the left. (Matthew 25:31, 33)

...when the Son of man sits on the throne of His glory..., He will judge the twelve tribes of Israel. (Matthew 19:28)

...the Son of man will come in the glory of His Father..., and then He will repay each person in accordance with his works. (Matthew 16:27)

Watch...always, that you may be held worthy...to stand before the Son of man. (Luke 21:36)

...the Son of man is coming at an hour you do not expect. (Matthew 24:44, Luke 12:40)

...the Father judges no one, but has committed all judgment to the Son..., because He is the Son of man. (John 5:22, 27)

The Lord calls Himself the Son of man when the subject is judgment because all judgment is made in accordance with the Divine truth that is in the Word. That this is what judges everyone is something the Lord teaches in John:

If anyone hears My words and yet does not believe, I do not judge him; for I did not come to judge the world.... ...the Word that I have spoken, it will judge him in the last day. (John 12:47-48)

And elsewhere:

(The Son of man did not come) to judge the world, but that the world through Him might be saved. He who believes in Him is not judged; but he who does not believe is judged already, because he has not believed in the name of the only begotten Son of God. (John 3:17-18)

That the Lord does not judge anyone to hell or cast anyone into hell, but that it is the evil spirit himself who judges and casts himself, may be seen in the book Heaven and Hell 545-550, 574.

The name of Jehovah, of the Lord, and of the Son of God, means Divine truth, thus also the Word, which originates from Him, is about Him, and so embodies Him.
