Also, I saw a program on the television that said Jesus was a Jewish King. It is so confusing. I wish Christians would just make one book that says what they all beleive in. Was he a King?
Jesus is a "king," but he is not a king in the usual literal manner of other kings we know from history. He is a very different kind of king. What we need to know about this can be found in the Bible, which I'll explain some here.
When the Jews were trying to convince the Roman authorities to crucify Jesus, they accused Jesus of claiming to be a king. There actually was some truth to this claim, but the Jews wanted to make the Romans fear that Jesus was leading an insurrection against Caesar (John 19:12), who was the king (or emperor) of the Roman empire. On hearing this, the Romans (a governor by the name of Pilate) asked Jesus about this accusation:
33 So Pilate entered his headquarters again and called Jesus and said to him, “Are you the King of the Jews?†34 Jesus answered, “Do you say this of your own accord, or did others say it to you about me?†35 Pilate answered, “Am I a Jew? Your own nation and the chief priests have delivered you over 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 have been fighting, that I might not be delivered over to the Jews. But my kingdom is not from the world.†37 Then Pilate said to him, “So you are a king?†Jesus answered, “You say that I am a king. For this purpose I was born and for this purpose I have come into the world—to bear witness to the truth. Everyone who is of the truth listens to my voice.†38 Pilate said to him, What is truth?†(John 18:33-40, ESV)
Jesus did not deny that he was a king, but he did make known that he was a very unusual type of king ("My kingdom is not of this world").
After questioning Jesus, Pilate did not fear any insurrection "of this world" from Jesus, but he wanted to appease the Jews who he did fear, so he had him crucified anyway. When Pilate then had Jesus crucified, he put a sign above Jesus's head:
19 Pilate also wrote an inscription and put it on the cross. It read, “Jesus of Nazareth, the King of the Jews.†20 Many of the Jews read this inscription, for the place where Jesus was crucified was near the city, and it was written in Aramaic, in Latin, and in Greek. 21 So the chief priests of the Jews said to Pilate, “Do not write, ‘The King of the Jews,’ but rather, ‘This man said, I am King of the Jews.’†22 Pilate answered, “What I have written I have written.†(John 19:19-22, ESV)
This sign "The King of the Jews" was written by Pilate to mock what the Jews were saying, and the Jews objected to it because they really didn't believe in it.
The remarkable thing about this was that neither the Jews nor the Romans believed Jesus was a king, but the truth of Jesus being a king was so powerful that even those who did not believe Jesus was a king were nevertheless compelled to say he was king. This same point was shown earlier before Jesus was handed over to be crucified:
37 As he was drawing near—already on the way down the Mount of Olives—the whole multitude of his disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen, 38 saying, “Blessed is the King who comes in the name of the Lord! Peace in heaven and glory in the highest!†39 And some of the Pharisees in the crowd said to him, “Teacher, rebuke your disciples.†40 He answered, “I tell you, if these were silent, the very stones would cry out.†(Luke 19:37-40, ESV)
Jesus was saying at that time that if people withheld saying that Jesus was a king, the very stones (which aren't even living things) would cry out that it is so.
Jesus also was descended from King David of Israel. So, by birthright he had the right to be king. Many centuries before Jesus was on Earth, God had prophesied to King David about such a future king that would descend from him and whose "throne shall be established forever" and that "I will be to him a father, and he shall be to me a son":
11 When your days are fulfilled to walk with your fathers, I will raise up your offspring after you, one of your own sons, and I will establish his kingdom. 12 He shall build a house for me, and I will establish his throne forever. 13 I will be to him a father, and he shall be to me a son. I will not take my steadfast love from him, as I took it from him who was before you, 14 but I will confirm him in my house and in my kingdom forever, and his throne shall be established forever.’†15 In accordance with all these words, and in accordance with all this vision, Nathan spoke to David. (1 Chonicles 17:11-15, ESV)
There are deep mysteries here. You will not find a simple answer on this question. Jesus himself refused to give a simple answer because a simple Yes or No is insufficient for understanding: a "kingdom not of this world" is not a type of kingdom that worldly people like us can easily relate to, but the many quotes in the Bible from Jesus offer some understanding of what he had in mind.
Jesus has more than one role, including prophet, priest, and king. We need to keep in mind though what Hammer said about not misinterpreting this too literally because these are only ways of expressing the deep thoughts of God in ways humans can hope to relate to:
Jesus is not the son of God, as men mean "son". Muslims are very literal-minded. Jesus is the incarnation of God.
