A Nobleman and His Kingdom

Why did Christ have to be 'inspected'? Why did they refuse to have Christ reign over them? Why was the servant to be judged by his own words? Who are these enemies of Christ? How is Christ the Kingdom and the Key to it? Why was the hearts of the disciples troubled? Has the cross always been purposed for both Jew and Gentile? How was Christ speaking of the cross when He said, "I go and prepare a place for you"? Can you understand the second coming of Christ without understanding the first?
