Jesus said that his words are the words of God. Jesus said that his words came directly from God.
Jesus warned his disciples not to allow anyone to call them "Teacher" or "Master" saying that they had only one teacher and one master and that is the Christ. (Matt 23:8-10)
Jesus really was, and is, and always will be God. Jesus said that he was God, that he was the Son of God and that he was the long-awaited Jewish Messiah.
God acknowledged Jesus as his son. We have the words of witnesses that say that God spoke with a voice that could be understood by people and confirmed that Jesus was his son. He also commanded that people should listen to Jesus.
