One thing I have observed is many think the demonstration of the work of unseen Spirit was not a demonstration of the lamb of God who had already slain from before the foundation of the world but the actual working out of it . God is not a man as never was never could be.
Christ of His own flesh informs us it did not profit for it is rather the unseen Spirit that does work to quicken our souls as we walk by faith the unseen . It was necessary that he did come incorruptible flesh that aged in a process of dying typified as sinful to put away sin in the flesh..... again as a demonstration of the work already finished from before the foundation of the world
Romans 8:3For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of
sinful flesh, and for sin, condemned sin in the flesh:
In order to establish a perfect type of the character and nature of the priesthood of the Lord, there was no man who could be a perfect type and so God Himself appeared in the
form of a man as that seen . He did not take on a human nature. Melchizedek did not become man as He did when Jesus Christ became man, but He did appear in the form of a man, in the person of Melchizedek, again in order to set up a type, a perfect type of the eternal character of the priesthood of the Jesus .
Seeing God cannot die his corruptible body was kept from corruption for three day .The same body of flesh was raised .He was therefore raised according to the unseen spirit of holiness. There is no such thing as flesh of holiness.(a Catholic idea)
Romans 1:4 And declared to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead:
Having finished the demonstration be fore he return to the unseen glot ry he had with the father Jesus left clear instructions, that even though some did know him after the flesh that did not profit from then on we know long look for another fleshly demonstration of the power of the Spirit. We walk by faith the eternal not seen
Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh,
yet now henceforth know we
him no more.2 Corinthians 5:16
