There are lots of smart ways to respond to a punch, and Qi Gong can teach you several of them. They don't necessarily result in the other person being flattened (although they can), but they do result in his punch doing you absolutely no damage whatsoever and throwing him right off balance at the same time. After a short while he gets the idea that he'd better not try punching you again. This is a smart way of turning the other cheek when it comes to punches. :-) And it doesn't involve getting angry or hating the other person. Yet it's extremely effective.

The "turning the other cheek" passage in Jesus' teachings was a metaphor for an inner action, not an outer one. A psychological movement rather than a physical one.

When you get angry or hateful you have put yourself in a toxic emotional condition, and it's not good for you or anyone else. When you remain calm but take an effective defensive action, you are not in a toxic emotional condition.

Angry people go beyond mere defence. They go on the attack and attempt to hurt, to damage, to humiliate, to destroy. This is not helpful to anyone, and it's downright ugly.

Turning the other cheek means continuing to love and respect other beings, regardless of their behaviour...but it does NOT mean surrendering to their bad behaviour and letting them get away with it.

As for Jesus being "the Son of God", everyone is the Son or Daughter of God. Everyone. And he was demonstrating that in no uncertain terms and stating it, but his followers didn't get it. They turned him into an idol. He also called himself the Son of Man. Everyone is that too. If you were born into this World, you are the Son or Daughter of Man, and of God.
