Hashem gives a child to BOTH a mother and a father, as a responsibility;
and He makes BOTH parents responsible for the child’s upbringing, which makes it important for BOTH parents to know the correct Halacha.
Instilling the correct values in a child is easier when it’s started as early in life as possible.
If the child is over Bar Mitzvah or Bas Mitzvah age and persists in violating the Halacha, even when the parents do their best in trying to teach the correct Halacha;
then ulimately, that child will be held responsible for the sin; NO EXCUSES. Rebelliousness is not an excuse. Not liking the way that the parent reproves is not an excuse.
Eventually, that child will grow into an adult and will be held responsible for his or her actions, because that person deliberately did not want to observe the Halacha correctly.
If the punishment is not received in This World, then C”V it will be received in the Next World, which is much worse.
Jews must be aware that Hashem is watching them every second and must act and dress in the modest ways, established by Chazal.
“Shivisi Hashem L’Negdee Tamid.”
“I keep Hashem before me, always.”
The Yetzer Hara tries to get us to sin and to rationalize the sin.
It is our job to fight off the Yetzer Hara.
