Jesus' kingdom

“Jesus said, ‘My kingdom is not of this world. If it were, My servants would fight to prevent My arrest by the Jews. But now My kingdom is from another place.’” John 18:36
There is a huge difference between the kingdom of Christ, and any other worldly kingdom. Worldly kingdoms and governments are inherently selfish. Consider how easily taxes are required and interest on them is charged, yet how hard it is to claim rebates when these are overpaid. Consider the disastrous outcome to a nation because of a tyrant’s selfish whims.
Jesus’ kingdom does not operate on the world’s principles. Instead of ‘look out for number one’, it is “consider others as better than yourselves” (Phil. 2:3). Instead of ‘get what you can, and can what you get’, it is “be generous and willing to share” (1 Tim. 6:18). It is “the last will be first, and the first will be last” (Matt. 19:30, Matt. 20:16, Mark 10:31, Luke 13:30).
Jesus’ kingdom is wherever He has free reign. His kingdom is a spiritual kingdom. It is in the hearts of those who obey Him.
