Jesus is dead, so he can't represent anybody.
Thats the whole point, his death(physical).
It is through his death that he represents. It is how we are saved. It is why the world is the way it is now.
What Jesus did affects even you, whether you realize it or not.
It's up to you to seek why. He left with some words, and a good example of how to live a life to be with God.
By seeking him, you will find him. He left us his Holy Spirit, and when you experience this spirit, you will be a witness.
Acts 1:
8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."
That is what is claimed to have been said by Jesus in the bible.
