If I am not alone then there must be another person standing by, and I cannot send myself somewhere, I would just GO there.
"But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."
-- John 14:26
To anoint is like giving a blessing. The priesthood of God is used to bless and help others, not yourself. Being selfish is against the will of the Lord, and prevents one from exercising the priesthood. When Christ was baptized by this same priesthood authority, 'God was with him'. I cannot be with myself, I simply am myself.
"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
The Holy Ghost has the form of a body all on his own, and if Christ was in the water then how could He be speaking from Heaven. 'Thou' and 'Thee' are pronouns like 'you' and are used when talking with someone else, not yourself.
This was realized about 300 years later when a 14 year-old farmboy in New York was reading the Bible, which was made possible by Tyndale's efforts to translate it into English.
Excerpts from the history of how this farmboy, Joseph Smith, learned more about scripture than an educated priest, is as follows. For the entire record see Joseph Smith History.
"There was in the place where we lived an unusual excitement on the subject of religion.
"During this time of great excitement my mind was called up to serious reflection and great uneasiness; but though my feelings were deep and often poignant, still I kept myself aloof from all these parties, though I attended their several meetings as often as occasion would permit....but so great were the confusion and strife among the different denominations, that it was impossible for a person young as I was, and so unacquainted with men and things, to come to any certain conclusion who was right and who was wrong.
"In the midst of this war of words and tumult of opinions, I often said to myself: What is to be done? Who of all these parties are right; or, are they all wrong together? If any one of them be right, which is it, and how shall I know it?
"I was one day reading the Epistle of James, first chapter and fifth verse, which reads: If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.
Joseph Smith was called as a Prophet of God, to restore the church that Christ had established during His mortal ministry. Through him we have the Knowledge that God the Father and His Son Jesus Christ appeared in the year 1820, side by side.
In regard to the Godhead the scriptures teach that They are each individual, yet one in purpose. Separate physically, but united spiritually. Even as I and my mortal father are united in our labors when we go out into the field to work, so also was Christ united with the Father while laboring here in His vineyard.
"Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me."
The Father, the Son, and the Spirit are not each other. However they each hold the title of God.
