Why did Christ "need" Spirit as His guide is an enigma which +Paul did not explain at all, as far as I am concerned, and it remains an enigma just as the Spirit descending on Him at the Baptism in the River Jordan.
If one concentrates on the differences between Jesus Christ as a man and Jesus Christ as God, he is apt to see Jesus as two persons when He is One Person with two facets.
Heres one way to visualize it:
Likewise, Jesus is the express image of the Fathers person. Again, worthy of meditation that there is no delineation between the image of the person and the person and yet there is a difference. Meditate not on a reflection of an image, like a mirror but the image itself.
Further, I assert that there is no delineation and yet a difference in the seven Spirits before God:
If God in three Persons or Jesus in two facets or the Spirit in seven - were each an Identity according to Aristotles Law of Identity - the following would not be logical:
And the Holy Ghost descended in a bodily shape like a dove upon him, and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased. Luke 3:22
And Jesus being full of the Holy Ghost returned from Jordan, and was led by the Spirit into the wilderness, - Luke 4:1
For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure [unto him]. John 3:34
[Even] the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. John 14:17
But when the Comforter is come, whom I will send unto you from the Father, [even] the Spirit of truth, which proceedeth from the Father, he shall testify of me: - John 15:26
Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. - John 16:7
And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. Acts 2:4
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. Romans 8:9
All my loyal and my much-loved companions,
They approve of me and share my code.

Good point.. I am an engineer, a husband. a father, grand father, and great grand father.. all at the same time.. Actually I'm more things than that..
So is Jesus.. much more.. The Earthy observer can be limited by his observations.. and the spiritual observer by his spiritual observations.. Mixing those limitations can get dicey..
The pain of an earthy life can facet you.. some more than others.. You know, A-G it takes a gemologist to be a christian observer.. don't you think.?
