Notice the Pasuk (verse) says, “Musar Hashem beni al tim'as.” Hashem turns to every single Jew and tells them, “My son, I’m giving you yissurim (discomfort). I’m disciplining you for your own benefit. You’re my son. I love you. Don’t look at the yissurim that you get as a pain in the neck. Understand that when I give you discomfort and when I give you yissurim, it’s for your own benefit, because I want you to come back.” Utilize the opportunity of yissurim.
None of us want yissurim, and we daven (pray) for it, not to give us yissurim. But when a person gets yissurim anyway, he has to appreciate it. There’s good in it. There’s something to appreciate. When a person is going through a hard time, when a person is going through pain, when things are not going as planned, although we wish it had never happened to us in the first place, understand that if it is happening to you, there’s a big plus to it.
That plus is that Hashem cares about you. If Hashem gave you that pain, it means you’re not just a random person on the shelf. No, it’s because Hashem cares about you, and He wants you to change and come back to Kadosh Baruch Hu (the Holy One, blessed be He). See, yissurim is a good sign. Yissurim is a sign that you’re capable of a lot, and Hashem has high expectations of you, and He wants you, yes you, you, to come back to Him. That’s what gives you the pain. Musar Hashem beni al tim'as: I’m doing it for your own benefit, and don’t be disgusted from it, don’t despise it.
