Why would you pray for the human flesh, when YAHshua HaMashiach literally told us that we are not of this world?

They are not of the world, even as I am not of the world.

17 Sanctify them through thy truth: thy word is truth.

18 As thou hast sent me into the world, even so have I also sent them into the world.

19 And for their sakes I sanctify myself, that they also might be sanctified through the truth.

20 Neither pray I for these alone, but for them also which shall believe on me through their word;

21 That 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.

22 And the glory which thou gavest me I have given them; that they may be one, even as we are one:

23 I 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.

24 Father, 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.

25 O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.

26 And 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. John 17:16-26 (KJV)
