Rabbi Twerski wrote the following on this topic: Don't we have strong yiras shamayim?
B"H, we have wonderful yeshivos and seminaries. We have glatt kosher meat, chalavyisrael, pasYisrael and kemachyashan. But listen to the Talmud. When Raban Yohanan ben Zakai was in his last days, his talmidim asked for his beracha. He said, "May your fear of Hashem be as great as your fear of people." His talmidim were shocked. "Is that what you think of us?" Raban Yohanan said, "Halevai you would achieve that! When a person does an aveira he is concerned that no person should see him. It does not bother him that Hashem sees him" (Berachos 25b).
Just think of it! The talmidim of Raban Yohanan ben Zakai! People whose greatness in Torah and kedusha is beyond what we can imagine, yet he felt that they might be lacking in yiras shamayim. How can we say about ourselves that we have adequate yiras shamayim? Remember what Chovas Halevavos says, "You may be asleep, but the yetzer hara is awake." Awake and unrelenting.
What can we do to increase yiras shamayim? Rashi provides the answer." To observe those mitzvos that we tend to trample on" (Devarim 7:12). B"H, we do not trample on kashrus,on Shabbos, or on chametz on Pesach, but unfortunately, we may trample on middos: kaas, lashon hara, kinah, sinah, ga'ava, shekker. We should keep before us the words of Rebbe Chaim Vital, that we should take even greater precaution with middos than we do with aveiros! Middos is the key to yiras shamayim.Middos gives the person a sense of kedusha and dignity that he would not allow himself to soiled with the tumah of the internet.
Let us be honest with ourselves. Do we sometimes lose our temper? The Talmud says that this is equivalent to avodah zara. Do we sometimes listen to or speak lashon hara, which is equivalent to the three cardinal sins of avodah zara, shefichas damim and ariyos? Do we sometimes deviate from the truth? No amount of chumros can be considered yiras shamayim if we are not meticulously careful about middos.
It is easy to buy kosher food. It is not easy to become master of our middos. It may be the most difficult challenge of our lives. But think of the person who will drive ten hours for fear that he may be exposed to the swine flu virus and how disastrous this can be to his grandchildren. If our homes do not become fortresses of true yiras shamayim, our children are at risk of being infected by the virus of the internet. Remember the words of Avraham Avinu "There is just no fear of G-d in this place." Without true yiras shamayim nothing else will work.
