[Jhn 18:33-37 NKJV] 33 Then Pilate entered the Praetorium again, called Jesus, and said to Him, "Are You the King of the Jews?" 34 Jesus answered him, "Are you speaking for yourself about this, or did others tell you this concerning Me?" 35 Pilate answered, "Am I a Jew? Your own nation and the chief priests have delivered You to me. What have You done?" 36 Jesus answered, "My kingdom is not of this world. If My kingdom were of this world, My servants would fight, so that I should not be delivered to the Jews; but now My kingdom is not from here." 37 Pilate therefore said to Him, "Are You a king then?" Jesus answered, "You say [rightly] that I am a king. For this cause I was born, and for this cause I have come into the world, that I should bear witness to the truth. Everyone who is of the truth hears My voice."
Christ has a Kingdom
Christ’s kingdom is a real one. It has a king - the Lord Jesus Christ. [Isa 9:6-7 NKJV] 6 For unto us a Child is born, Unto us a Son is given; And the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace. 7 Of the increase of [His] government and peace [There will be] no end, Upon the throne of David and over His kingdom, To order it and establish it with judgment and justice From that time forward, even forever. The zeal of the LORD of hosts will perform this. In fact, in this same conversation, Jesus told Pilate, "You say [rightly] that I am a king.”
