If I had a fire in my house, does that mean I have to think about doing תשובה?
If a fire took place, חלילה, in somebody’s house, does he have to think about תשובה? Absolutely. Not only if a fire took place. Even if a person touched a hot pot by accident and burned a finger. Of course, you have to run into the bathroom and run it under cold water and put some cream on it. That’s the first thing. But you also have to think, “Why did this happen to me?”
We learned אם רואה אדם שיסורין באין עליו יפשפש במעשיו (Brachos 5a). If one sees that any sort of trouble is coming upon him, he should search out his deeds and do תשובה. Certainly he should think that. Maybe I was pointing at somebody and talking לשון הרע with my finger. Or something else. Of course you have to think. That’s why Hashem sent it.
We forget about Hashem, so He reminds us. Now, if you had been thinking about Hashem in the right way, He wouldn’t have burned your finger. And therefore, anything that happens in this world is for the purpose of making us think about Him. And ignoring these things, is ignoring the reason that you’re in this world – which is to become more and more aware of Hashem.
