We are all familiar with the question put to Christ about paying the poll tax to Caesar (Matthew 22:17-21). Christ held up the coin and ask whose inscription was on it, then he told them to render to Caesar the things that are Caesar's and to God the things that are God's. But earlier in Matthews Christ even when as far as to teach us not to use loopholes to avoid taxes. Christ was not obligated to pay the taxes in Matthew 17, but Christ told Peter that he was not to offend the tax collectors and then proceeded to demonstrate to him that even the tax money is a gift from God.
Christ tried to teach us that there is nothing of value on this earth that man should fight to hold onto.
Matthew 17
24 When they came to Capernaum, those who collected the two-drachma tax came to Peter and said, "Does your teacher not pay the two-drachma tax?" 25 He said, "Yes." And when he came into the house, Jesus spoke to him first, saying, "What do you think, Simon ? From whom do the kings of the earth collect customs or poll-tax, from their sons or from strangers ?" 26 When Peter said, "From strangers," Jesus said to him, "Then the sons are exempt. 27 "However, so that we do not offend them, go to the sea and throw in a hook, and take the first fish that comes up; and when you open its mouth, you will find a shekel. Take that and give it to them for you and Me."
Matthew 5:40
As for the one who wants to sue you and take away your shirt, let him have your coat as well.
