The Jews teach that prior to Adam/Eve fall their skin was almost "transparent" from the "light of the spirit" inside them that kept them "ALIVE".
After the Fall, "BLOOD" became the "medium" which sustains the "life of the flesh".
We have to be willing to "shed blood" to crucify the "old man" (flesh) so we can "live by the spirit", "AGAIN". (Redeemed)
John, in Revelations, saw God.
Re 4:2 And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne.
Abraham also saw God, but in an "earthly form".
Heb 7:1 For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;
2 To whom also Abraham gave a tenth part of all; first being by interpretation
King of righteousness, and after that also King of Salem, which is, King of peace;
3 Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.
King of righteousness,
King of Salem, (Jeru-Salem)
King of peace;
Jesus is the "PRINCE", or "son of the King".
Isa 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father,
The Prince of Peace.
Jesus is also our "Priest".
Heb 6:20 Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec.
Of course if you have a problem with the trinity, you'll have a problem with this.
