If you really knew me, you would know my Father as well. From now on, you do know him and have seen him." (John 14:7)
 
Here Jesus (pbuh) is saying that if you know me, you know God i.e. if you follow me, you are indirectly following Almighty God. Seeing God here means knowing God as we can see from the verse.
 
_Philip said, "Lord, show us the Father and that will be enough for us." (John 14:8)
 
Here Philip is asking Jesus (pbuh) to show him God. The Bible says
 
“No one has ever seen God” (John 1:18)
 
“But," he (God) said, "you cannot see my face, for no one may see me and live." (Exodus 33:20)
 
Note : The word “God” in bracket is mine.

Being a Jew, he knew that no man can see God and live, making such an absurd request to Jesus (pbuh) of showing the father. So Jesus (pbuh) replies
 
_Jesus answered: "Don't you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father. How can you say, 'Show us the Father'? (John 14:9)
 
Jesus (pbuh) is saying to Phillips that he had been with him for so long and still making such an silly request of showing God, so Jesus says that “Anyone who has seen me has seen the father” meaning if you know me, you know Almighty God as well. You follow my teachings; you are following the teachings of Almighty God.
 
In context, we come to know that anyone who knows Jesus (pbuh) i.e. anyone who follows Jesus (pbuh) is indirectly following Almighty God to which we have no objection.
