You ask what the Son of Man, our Lord God and saviour, who chose Jesus from among the Israelites and filled him with "HIS WORDS" and sent him to the people to speak in 'HIS NAME', all that the Lord commanded him to say, meant when He said; "When you lift up 'The Son of Man' You will know 'I Am WHO I AM.'

"THE SON OF MAN" develops within the body of mankind, just as mankind developed within the bodies of our animal ancestors, He is the son promised to Eve who is to crush the head of Satan.

When Adam was dying at the age of 930 in the (Thousand years) day that he ate of the forbidden fruit Eve asked him when she would follow him, and she was told that she would be united to him in six days, and it is when EVE, who has become the great pregnant androgynous body of mankind, dies after the Great seventh day Sabbath of one thousand years, six days after the death of Adam, that all physical life forms on this planet are incinerated, and the umbilical cord that binds the evolving spirit in man is severed and "The Son of Man" is born into the world.

It is He who then mentally descends into his dead past and is chosen by Abraham as his invisible God, who said to Abraham; "In blessing, I will Bless you, and in multiplying, I will multiply you."

It was "THE SON OF MAN" 'Who I Am=JHWH' who said to Moses in Deuteronomy 18: 18-19; I will raise them up a Prophet from among their own people, like unto thee, and will put ‘MY WORDS’ in his mouth; and he shall speak unto them all that I shall command him. And it shall come to pass, that whosoever will not hearken unto ‘MY WORDS’ which he shall speak in ‘MY NAME’, I will surely Punish.

So when the Lord said through his earthly host body Jesus; ""When you lift up 'The Son of Man' You will know 'I Am WHO I AM.' He was saying that "I" 'The Son of Man' who filled the Israelite Jesus with my spirit= MY WORDS, am the God of Abraham, Isaac and Jacob, the only begotten Son of God the Most High in the creation.

Hebrews 10: 5-6; For this reason, when Christ (The Anointed One) was about to come into the world, he said to God: “You do not want sacrifices and offerings, but you have prepared a body for me. You are not pleased with animals burnt whole on the altar or with sacrifices to take away sins. Then I said, ‘Here I am, to do your will, O God, just as it is written of me in the book of the Law.’ ”

The Body that His Father had prepared for him, was the man Jesus, who was filled with the spirit of our Lord God and saviour, who was to lay down his life for the sins of the flesh in which he had developed, who, on the day that Jesus was Baptised, the spirit of the Lord descended upon him in the form of a dove, as the heavenly voice was heard to say; "You are my Son, (My chosen heir and successor) 'THIS DAY' I have begotten thee."

Hebrews 5: 7-10; In his life on earth Jesus made his prayers and requests with loud cries and tears to God, who could save him from death. Because he was humble and devoted, God heard him. But even though he was “A” son of God, he learnt through his sufferings to be obedient. When he was made perfect, (In his obedience) he became the source of eternal salvation for all those who obey him, and God declared him to be high priest, in the priestly order of Melchizedek.

In order to be the ‘IMAGE’ of the invisible 'Son of Man', Jesus had to be totally obedient to the inner commands, obedient even unto his cruel death upon the cross.

Peace.
