John 14:10 "Do you not believe that I am in the Father and the Father is in me? The words that I speak I do not speak on my own. The Father who dwells in me is doing his works."
So the Father is in Jesus. He dwells in Jesus. Clearly he made Jesus his main dwelling, so therefore those who saw Jesus, saw the Father through him. But still they are two different beings. Jesus clearly distinguished between himself and the Father, both in this verse, and also in the verse you quoted, verse 7. There he called the Father "my Father". Therefore 2 beings, Jesus and his Father.
