You are incorrigible with God's Word, which means unregenerate and rebellious against God's written Word.
John 14:8-9
8 Philip saith unto Him, "Lord, shew us the Father, and it sufficeth us."
9 Jesus saith unto him, "Have I been so long time with you, and yet hast thou not known Me, Philip? he that hath seen Me hath seen the Father; and how sayest thou then, 'Shew us the Father'?"
KJV
That doesn't answer Robert's question. To give more context to the verses that you quoted, Jesus had just said:
(6) Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father, except through me.
(7) If you had known me, you would have known my Father also. From now on, you know him, and have seen him.”
meaning that Jesus' character was just like God's, so having known Jesus they also knew what kind of a person God is. The Greek word that's translated as 'know',
ginosko, means, according to the Online Bible Greek Lexicon:
1) to learn to know, come to know, get a knowledge of perceive, feel
1a) to become known
2) to know, understand, perceive, have knowledge of
2a) to understand
2b) to know
3) Jewish idiom for sexual intercourse between a man and a woman
4) to become acquainted with, to know
The Greek word translated as 'seen',
horao, means, according to the Online Bible Greek Lexicon
:
1) to see with the eyes
2) to see with the mind, to perceive, know
3) to see, i.e. become acquainted with by experience, to experience
4) to see, to look to
4a) to take heed, beware
4b) to care for, pay heed to
5) I was seen, showed myself, appeared
So by getting to know Jesus they had also perceived and experienced what God is like - loving, kind, compassionate, merciful and just.
Jesus then went on to say:
(10) Don’t you believe that I am in the Father, and the Father in me? The words that I tell you, I speak not from myself; but the Father who lives in me does his works.
(11) Believe me that I am in the Father, and the Father in me; or else believe me for the very works’ sake.
(12) Most certainly I tell you, he who believes in me, the works that I do, he will do also; and he will do greater works than these, because I am going to my Father.
(13) Whatever you will ask in my name, I will do it, that the Father may be glorified in the Son.
They had come to know God because it was God, Jesus' Father, who was speaking and working through His Son Jesus.
I think this is the answer that Robert was expecting:
John 17:1-8
(1) Jesus said these things, and lifting up his eyes to heaven, he said, “Father, the time has come. Glorify your Son, that your Son may also glorify you;
(2) even as you gave him authority over all flesh, so he will give eternal life to all whom you have given him.
(3) This is eternal life, that they should know you, the only true God, and him whom you sent, Jesus Christ.
(4) I glorified you on the earth. I have accomplished the work which you have given me to do.
(5) Now, Father, glorify me with your own self with the glory which I had with you before the world existed.
(6) I revealed your name to the people whom you have given me out of the world. They were yours, and you have given them to me. They have kept your word.
(7) Now they have known that all things whatever you have given me are from you,
(8) for the words which you have given me I have given to them, and they received them, and knew for sure that I came from you, and they have believed that you sent me.
