You need to believe that the world is an unnatural place. The world you live in, the world that you were gifted to be a part of, the world that you wake up into every single morning when you take your first breath in the morning—that world is not a natural place.
You see, Amalek came to fight the Jewish people. The reason Amalek came to fight the Jewish people is that they believed we were tired. They came for the stragglers, as the pasuk (verse) says: “They came and they tried to massacre all of those who were weak in the back.” That's what Amalek tried to do: those who were exhausted from the path, those in our world who we say are exhausted, exhausted from the journey of life. And Amalek came and targeted those people. Then Moshe Rabbeinu raised his hands, and those hands were supposed to be hands of faith, hands that instill in the Jewish people a strength: naturally, we're tired; naturally, these people are stragglers; naturally, we can't win. But God does it right. And God can't just run His world in a natural way. Hashem doesn't take care of you and me in a natural way. The fight against Amalek represents this ideal: Hashem protects us in an unnatural way.
If you can acknowledge that you live in an unnatural world, if you can acknowledge that Hashem gives you unnatural gifts, if you can acknowledge that your life is a series of unnatural miracles, you should be able to have the strength to respond to a friend in an unnatural way. A Jew is supposed to be living in an unnatural bubble. That means we're living in a space where we see Hashem again and again and again. And if I could see Hashem in all the good, if I could see Hashem in all the miracles, then I could also see Hashem in your insult and let it go. Because my life isn't natural. So why should I respond to you naturally? My life isn't. The good and bad are completely from Him. So why should I get frustrated with you? I am living in His world, not your world. I'm living by what He wants to happen to me, not by what you decide to happen to me. The world I'm in is an unnatural place. The world I'm in is a world where Amalek can never exist. The world is a world that I believe, I don't care if I'm tired and exhausted, I still have unnatural power and unnatural strength. And if I have that unnatural strength gifted to me by God, and if I have that unnatural strength gifted to me by Hashem, and it's infused inside of me and I'm living in that kind of bubble, then I have the power and the strength to have an unnatural response to how you hurt me.
