Yes, this world is the devil's, leave it to the devil, who is the father of the Jews, that they have given themselves to his house by rejecting their messiah. As Jesus said "render unto Ceasar what is Ceasar's, and unto God what is God's". I have given you quote after quote, all from Jesus, he ay have told you to buy a sword, but did he ever tell you to strike someone with it? Perhaps he was being metaphorical, as he had been when he said "I have come to bring not peace, but a sword" he then clarified "I have come to divide father against son, daughter against mother, brother against brother, and house against itself". His "sword" was not a physical one, but a metaphor for how divisive his message was, what he was cutting with was not steel, but truth, and what he was cutting was not a physical bond, but an immaterial one. Later on, he is more clear as to what he was referring to: "if you do not hate your brethren, if you do not hate your father and mother, brother and sister, if you do not hate yourself also, then you cannot be my disciple". You must love Christ above all to be a Christian, and you must hate all earthly things, including hating your family and yourself, indeed, his followers left their families for him, and took on lives of outcasts living in poverty, praying, worshipping, and preaching. You must turn the cheek yet to be struck to your enemy who had struck you, this asks him to see you as an equal before he strikes you again, You must give up your sandals and robes if your sandals are being robbed from you, this shows your detachment from the world, and the generous spirit that provides everlasting bounty. You must welcome the stranger and provide for his every need above your own, for by doing so you welcome Christ. You must obey the slave master and serve him well, Jesus implores you to do so, for your wages lie in the hereafter, a great bounty for an obedient servant. You resist tyranny by being unbroken in spirit by it, some active revolt is not Christian rebellion, but the rebellion of the worldly man, and he has given himself over to the devil. Christ is very clear on that, to resist with your heart or hand or tongue is to violate his commands of his disciples and to forsake his example of how to rebel against persecution (allowing yourself to be crucified by your oppressors). God's law comes before all, and Jesus is the most direct word of God, his teachings come before anything else you may find in the Bible. "Why did he crash the moneychangers at the steps of the temple and drive them out with a whip? that's violent", he was not resisting the Romans, here, was he? he was not killing anyone, and as his whip was not fashioned of hide, it may not even have harmed them significantly, the worst he did was overturn some tables. Here he was admonishing his own people remembered the law of his people, the laws given to them by God, as was his duty as Rabbi. His actions are explicitly stated by him later on, He acted this way because they violated the laws of the Jews as orally given among the Jews by the Pharisees, and he had come to fulfill the law, not to change it. He said "you shall not make of my fathers house, a house of merchandise", according to the Talmud, business must be conducted away from the tabernacle, and one must not lend money to a fellow Jew, only to a gentile may money be changed. It seems this law predated the Talmud and was indeed a part of the oral law that Jesus sought to fulfill. You may not conduct business of this nature with fellow Jews, and you may not conduct business in the presence of the house of God. Look at Paul, a tax collector, the ultimate money changer, was he demonized in the Bible? no, he was a Jew who was made by the romans to collect information on his people while acting in the role of tax collector, Hearing od Christ and his followers, he reported this to the Romans, who persecuted them, and were not resisted by the Christians. Then he was struck blind on the road to Damascus, by the glorious light of God asking him "why do you persecute my people so?, and inspired to become a messenger of Christ, he was the founder of the Pauline church of Christ, which went on to be directly influential in the later universal church of Christ. That alone is enough to say that money-changing is not a deal-breaker, he was not struck dead, but blinded, and only temporarily, as his sight recovered thereafter, and he went on to be one of the most holy men in the Christian faith among Christ's followers.
