Correct. Keep up the good work!

Jesus answered, "My kingdom is not of this world. If My kingdom were of this world, then My servants would be fighting, that I might not be delivered up to the Jews; but as it is, My kingdom is not of this realm." John 18:36 (NAS)

Earlier in the book of John, Jesus perceived that the Jews wanted to make Him their earthly King.  The Jews did not understand that Jesus' kingdom was not of this world:

 Jesus therefore perceiving that they were intending to come and take Him by force, to make Him king, withdrew again to the mountain by Himself alone. John 6:15 (NAS) 

Jesus' Church:  A Kingdom Without End:

The prophet Isaiah foretold of the birth of Jesus saying in Isaiah 9:6-7:

"For a child will be born to us, a son will be given to us; and the government will rest on His shoulders; and His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace. There will be no end to the increase of His government or of peace... Isaiah 9:6-7 (NAS)

This earth will pass away and everything in it:

"But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the earth and its works will be burned up. Since all these things are to be destroyed in this way, what sort of people ought you to be in holy conduct and godliness, looking for and hastening the coming of the day of God, on account of which the heavens will be destroyed by burning, and the elements will melt with intense heat!" 2 Peter 3:10-12 (NAS)

But Jesus' church or kingdom will not be shaken:

"Therefore, since we receive a kingdom which cannot be shaken, let us show gratitude, by which we may offer to God an acceptable service with reverence and awe;" Hebrews 12:28 (NAS)
