Explain how Jews follow the teachings love your fellow human being as yourself

A large part of Jewish law is about treating people with kindness. The same body of Jewish law that commands us to eat only kosherfood and not to turn on lights on Shabbat, also commands us to love both Jews and strangers, to give tzedakah (charity) to the poor and needy, and not to wrong anyone in speech or in business. In fact, acts of kindness are so much a part of Jewish law that the word "mitzvah" (literally, "commandment") is informally used to mean any good deed.
