We have the great privilege to be Hashem's children, as it states (14:1) אתם בנים אלקיכם 'לה, "You are children of Hashem, your G-d." One might think that collectively, we are Hashem's children. The Alshich HaKodesh therefore explains that Hashem considers each Yid, individually, as His beloved child. This is a great honor, so great that it is hard to grasp its magnitude.
Even when we transgress the Torah, chalilah, Hashem views us as His children. This is Reb Meir's view in the Gemara (Kiddushin 36.) Reb Yehudah says that we are only called Hashem's children when we act correctly, but the Rashba (teshuvah 194) writes that the halachah is like Reb Meir. Regardless of how we act, we are always Hashem's children.
It states, תשימו ולא תתגדדו לא אלקיכם 'לה אתם בנים למת עיניכם בין קרחה, "You are children of Hashem, your G-d. You shall neither cut nor make any baldness between your eyes for the dead." Ibn Ezra writes, "Now that you know you are Hashem's children, and you know yourselves that Hashem loves you more than a father loves his son, do not injure yourself when something upsetting occurs because everything is for the good. Although we don’t always understand how it is for the good, we trust that Hashem, our Father only does what’s best for us. This can be compared to a child who doesn't understand his parents' ways but relies on them. That's how you should be with your emunah in Hashem." One should trust that Hashem is leading us in the best way, as a father would lead his children.
