The mystery of the son of man: The actions that I do in my Father's name testify on my behalf. John 10:25

The Gospel of John presents Jesus in a mysterious way. The Gospel of John recounts that after the wedding at Cana and the expulsion of the merchants from the temple, Jesus met Nicodemus at night, who, bewildered, told him: "Rabbi, we know that you are a teacher who has come from God" John 3:2.
According to the Gospel of John, Jesus presented himself as "son of man" to avoid being accused of being a false prophet, because according to the Book of Deuteronomy, the punishment for false prophets was death (Deuteronomy 13:5). But it so happened that Jesus, with his words and miracles, made many people uncomfortable, as did many prophets who suffered persecution, as the Bible relates. The death of John the Baptist even greatly disturbed Jesus, who feared suffering the same fate before fulfilling his mission in the world. This is why Jesus had to be very careful with his words at all times.
The Gospel of John relates that Jesus, while in Jerusalem, healed a man born blind, and thus Jesus presented himself as the light of the world, that is, as the personification of wisdom. He then also taught that he is the good shepherd, but this provoked those who wanted to condemn him to death, and so the discussion between Jesus and his enemies became heated. Jesus' enemies sought to have him declare himself as the expected Messiah so they would have grounds to accuse him before the authority of Rome and the Sanhedrin, but Jesus remained evasive.
And it happened that during the Feast of Dedication, Jesus was in Jerusalem, and more precisely in Solomon's Portico, and his enemies again rebuked him and said: "How long are you going to keep us in suspense? If you're the Messiah, tell us so plainly" John 10:24. So Jesus answered them: "I have told you, but you don't believe it. The actions that I do in my Father's name testify on my behalf" John 10:25.
Jesus, as the Father's envoy, always kept his identity in a mystery and only revealed himself as the Messiah to his disciples; to everyone else, he was simply the "Son of Man," a subtle and disguised way of saying that he is "God" who becomes the "Son of Man," or in other wors the personification of God's perfections. The teaching of Jesus as the second person of the Holy Trinity, along with the Father and the Holy Spirit, is something later, that was determined with the Council of Nicaea.
