Let's take a look at one of Yeshua's most intimate moments to understand how we can come into the Holy of Holies and the presence of YHWH.  Yeshua knowing he is about to meet His fate of laying down His life for our redemption.  He takes very little thought for Himself.  We will look at the whole chapter as there is gold in every verse.  Again, it starts with Yeshua's power over all flesh.  We can't miss that point anymore can we?  For the purpose of giving eternal life, to glorify YHWH on earth before all the people, to manifest YHWH's name to men.  YHWH, the Word, in the uncorrupted flesh. 

John 17:1These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:  2As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.  3And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.  4I have glorified thee on the earth: I have finished the work which thou gavest me to do.  5And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.  6I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word.  7Now they have known that all things whatsoever thou hast given me are of thee.  8For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me.  9I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine.  10And all mine are thine, and thine are mine; and I am glorified in them.  11And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are.  12While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.  13And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.  14I have given them thy word; and the world hath hated them, because they are not of the world, even as I am not of the world.

 John 17:15I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil.  16They are not of the world, even as I am not of the world.  17Sanctify them through thy truth: thy word is truth.  18As thou hast sent me into the world, even so have I also sent them into the world.

 John 17:9And for their sakes I sanctify myself, that they also might be sanctified through the truth.  20Neither pray I for these alone, but for them also which shall believe on me through their word;  21That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.  22And the glory which thou gavest me I have given them; that they may be one, even as we are one:  23I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.  24Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.  25O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.  26And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.

Those who YHWH received from YHWH were given knowledge of all things, including that Yeshua came from YHWH; Yeshua is glorified in us.  We are kept in YHWH's name, being one with Him as Yeshua is one with Him.  Yeshua declares we are not of the world because He is not of the world.  We are incorruptible because He is incorruptible.  We are one flesh with Him.  Yeshua is in us, as YHWH is in Him.  We are made perfect by being one with Yeshua and YHWH.  Yeshua asks that we may be with Him where He is that we may behold His glory.  He concludes by stating that we know YHWH sent Him in the uncorrupted flesh. 

I Corinthians 15:All flesh is not the same flesh, but there is one kind of flesh of men, another flesh of animals, another of fish, and another of birds. 40 There are also celestial bodies and terrestrial bodies; but the glory of the celestial is one, and the glory of the terrestrial is another. 41 There is one glory of the sun, another glory of the moon, and another glory of the stars; for one star differs from another star in glory. 42 So also is the resurrection of the dead. The body is sown in corruption, it is raised in incorruption. 43 It is sown in dishonor, it is raised in glory. It is sown in weakness, it is raised in power. 44 It is sown a natural body, it is raised a spiritual body. There is a natural body, and there is a spiritual body. 45 And so it is written, “The first man Adam became a living being.” The last Adam became a life-giving spirit. 46 However, the spiritual is not first, but the natural, and afterward the spiritual. 47 The first man was of the earth, made of dust; the second Man is the Lord from heaven. 48 As was the man of dust, so also are those who are made of dust; and as is the heavenly Man, so also are those who are heavenly. 49 And as we have borne the image of the man of dust, we shall also bear the image of the heavenly Man.

The scripture appears to be clear that there are two types of flesh of men, one of dust and one of heaven.  He further states that Yeshua is a life giving spirit.

Luke 24: 36 Now as they said these things, Jesus Himself stood in the midst of them, and said to them, “Peace to you.” 37 But they were terrified and frightened, and supposed they had seen a spirit. 38 And He said to them, “Why are you troubled? And why do doubts arise in your hearts? 39 Behold My hands and My feet, that it is I Myself. Handle Me and see, for a spirit does not have flesh and bones as you see I have.” 40 When He had said this, He showed them His hands and His feet. 41 But while they still did not believe for joy, and marveled, He said to them, “Have you any food here?”
