To see Jesus is to see all that we, as creatures of earth, can perceive of God our Father. We can't see God and we can't know Him. We can know Him through His Son, the Christ of God, The Messiah.
This is very similar to Jesus' statement to Philip:
John 14:7-11
"If you had known Me, you would have known My Father also; from now on you know Him, and have seen Him." Philip said to Him, "Lord, show us the Father, and it is enough for us." Jesus said to him, "Have I been so long with you, and [yet] you have not come to know Me, Philip? He who has seen Me has seen the Father; how [can] you say, 'Show us the Father'? "Do you not believe that I am in the Father, and the Father is in Me? The words that I say to you I do not speak on My own initiative, but the Father abiding in Me does His works. "Believe Me that I am in the Father and the Father is in Me; otherwise believe because of the works themselves.
