Many of us have stated our position on the Godhead (Trinity) on previous threads, but to offer a possible answer to your question highlighted in blue, the following passage must be understood because of what Jesus was claiming to Philip and the other disciples, read the following passage and give us your understanding of what was intended by our Lord ...
Jn 14:6-11
6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
7 If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.
8 Philip saith unto him, Lord, show 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, Show us the Father?
10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
11 Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake.
John 17:20-26
20 Neither pray I for these alone, but for them also which shall believe on me through their word;
21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
22 And the glory which thou gavest me I have given them; that they may be one, even as we are one:
23 I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
24 Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.
25 O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.
26 And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
To see Jesus is most assuredly to see the Father.
Acts 9:1-5
9
And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest,
2 And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.
3 And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven:
4 And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?
5 And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks.
But to see even the least of His brethren is to see Him!
Genesis 33:1-10
33
And Jacob lifted up his eyes, and looked, and, behold, Esau came, and with him four hundred men. And he divided the children unto Leah, and unto Rachel, and unto the two handmaids.
2 And he put the handmaids and their children foremost, and Leah and her children after, and Rachel and Joseph hindermost.
3 And he passed over before them, and bowed himself to the ground seven times, until he came near to his brother.
4 And Esau ran to meet him, and embraced him, and fell on his neck, and kissed him: and they wept.
5 And he lifted up his eyes, and saw the women and the children; and said, Who are those with thee? And he said, The children which God hath graciously given thy servant.
6 Then the handmaidens came near, they and their children, and they bowed themselves.
7 And Leah also with her children came near, and bowed themselves: and after came Joseph near and Rachel, and they bowed themselves.
8 And he said, What meanest thou by all this drove which I met? And he said, These are to find grace in the sight of my lord.
9 And Esau said, I have enough, my brother; keep that thou hast unto thyself.
10 And Jacob said, Nay, I pray thee, if now I have found grace in thy sight, then receive my present at my hand:
for therefore I have seen thy face, as though I had seen the face of God, and thou wast pleased with me.
