>I never said to let them abuse you.
Jesus was telling them to lead by example. If you show love to your enemy, you are giving them a chance to repent and change their minds, that they may become on of us, which is correct when you think about it. But if they insist on your demise, then like he said. If any of were my disciples, you would fight for me instead of handing me over to the Jews - who are about to kill me. When he told Peter put away the sword, he was saying that he already knew that he would deny him, so he knew what was in his future, because they won't put up a real fight.
