My Kingdom is not of this World
Is John 18:36 speaking, spiritually, of the Body of Christ coming into the great tribulation? Let's examine.
PARABOLIC RESPONSES: GOSPEL BURIED IN HISTORICAL CONVERSATION?
Joh 2:3-4 And when they wanted wine, the mother of Jesus saith unto him, They have no wine… Jesus saith unto her, Woman, what have I to do with thee? mine hour is not yet come.

FIGHTING: VENGEANCE ON BABYLON?
Joh 18:36 Jesus answered, My kingdom is NOT OF THIS WORLD: if my kingdom were of this world, then would my servants fight <75>, that I should not be delivered to the Jews: but now is my kingdom not from hence.
1Ti 6:12 Fight <75> the good FIGHT OF FAITH, lay hold on eternal life, whereunto thou art also called, and hast professed a good profession before many witnesses.
2Ti 4:7 I have fought <75> a good fight, I have finished [my] course, I HAVE KEPT THE FAITH:
Zec 14:2 For I will gather all nations AGAINST JERUSALEM TO BATTLE; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city.
Zec 14:3 Then shall the LORD go forth, and FIGHT AGAINST THOSE NATIONS, as when he fought in the day of battle.
Zec 14:14 And Judah also shall FIGHT AT JERUSALEM; and the wealth of all the heathen round about shall be gathered together, gold, and silver, and apparel, in great abundance.
Jer 51:30 The mighty men of BABYLON HAVE FORBORN TO FIGHT, they have remained in [their] holds: their might hath failed; they became as women: they have burned her dwellingplaces; her bars are broken.
Re 2:16 Repent; or else I will come unto thee quickly, and will FIGHT AGAINST THEM WITH THE SWORD OF MY MOUTH.

WORLD TO COME: POST TRIBULATION, REDEMPTION OF THE BODY?
Re 11:15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become [the KINGDOM] OF OUR LORD, and of his Christ; and he shall reign for ever and ever.

Re 21:1 And I saw a NEW HEAVEN AND A NEW EARTH: for the first heaven and the first earth were passed away; and there was no more sea.
Joh 18:36 appears to be parabolic of the fact that Christ had to endure the atonement without a fight. Spiritually, this would point to His Body in tribulation when the one-third was under judgment with the unsaved church. It was not a time for revenge, which comes at the revelation of Christ.
