Juan 5:27

And he gave him authority to execute judgment, because he is a Son of man.

Authority ... is the great word with reference to Christ. None of the apostles failed to be impressed with it. Matthew summarized it in Jesus own words as "all authority in heaven and upon earth" (Matthew 28:18).

Because he is a Son of man ... God would not judge the intelligent creation whom he fashioned in his own image, until first he himself had become a man in the person of the Son, in order that his judgment would therefore be more merciful, righteous, and just.
