It is written that if one offends you that you should turn the other cheek, not retaliate. I am no saint regardless of our last name is. I am here to provide you with a contemporary explanation and some guidance as to how to best put it in practice without upsetting the man upstairs or being driven to tears down here.
The whole idea behind turning the other cheek is to offer forgiveness or at the very least to stop the cycle of violence and/or injuries. If like the Babylonians we practiced "an eye for an eye" there would be plenty of situations where we would all be blind. Imagine that I accidentally poked out your eye, then in turn had an eye poked out; the natural progression says that two more eyes will soon be poked out. It would be a wise decision for someone to take the "higher road" and rather than repay an insult with an insult to do so with a smile.
Cycles and grudges.
There is no greater virtue than to be able to forgive those who have wronged you and have done nothing to repent. To continue down a path where every wrong-doing is repaid with the same could lead you astray from the beliefs that we are trying to instill in you. There is no way to be genuine, loving, caring when your every action is one motivated by anger and hatred because what has been done to you. In the end carrying on in such a manner is a cancer to your soul, to your character. It cause you to rot from the inside out.
The fine print.
There is an exception for every rule. I want you to be morally responsible, not a doormat. If someone does insult you respond to them, let them know how you feel, tell them that you will not stand by that. If someone should hurt you in any way I do not want you to stand there and take it. Avoid situations and people that can put you in danger; if those situations cannot be avoided, take the higher road.
Fight for yourself.
I would be lying if I told you that all people are capable of rational thought and that every situation could be dealt with in a "adult manner". The truth of the matter is that there are some bad people in the world. Real bad apples. In the event that you should come across one of them. FIGHT BACK! Theodore Roosevelt famously said to "speak softly and carry a big stick". I want you to be respectful, to be a model citizen, and above all else to never lose your integrity. When all that doesn't work... HIT THEM WITH THE BIG STICK.
Or call your father, I will make sure that those problems go on a permanent vacation.
