Matthew 22: Jesus answer questions from his enemies

Jesus is in Jerusalem. Pharisees, Sadducees and Herodians are against Jesus. They are enemies among themselves but they found an enemy in common: Jesus. These three groups of people ask questions to Jesus in order to test him and put him in a difficult situation. For instance: what is the position of Jesus about Roman taxes: pro or against? Some Jews hate Rome; and they are against Roman taxes. However if Jesus were against  Roman taxes he becomes against Rome and Caesar. Here is a difficult question in order to trap Jesus. We read:

18-19 Jesus knew they were up to no good. He said, “Why are you playing these games with me? Why are you trying to trap me? Do you have a coin? Let me see it.” They handed him a silver piece.
20 “This engraving—who does it look like? And whose name is on it?”
21 They said, “Caesar.”
“Then give Caesar what is his, and give God what is his.”  

Jesus didn't preach any revolt against the system, against Rome. In a way, he said to submit to Rome. He saw many ways to submit to the Lord and to Rome because most of time there's no conflict between Rome and the Lord even though Rome is a kingdom of this world and essentially evil. Christian pay the taxes and this is not evil (by contrary, it is good). Jesus is the king of the kingdom of heaven, but he came not to destroy the kingdom of this world, but to destroy sin and death. I am a sinner and my destine is the death. Jesus came to free me. Peter, John, etc. were Jews that ,very likely, had Rome as an enemy, but their great enemy was sin and death.

It is very easy to think that a kingdom comes when it win battles. Can we imagine a kingdom that wins by being submissive? Jesus way is very different, it is divine.
