One thing about mitzvot is that every Jew is obligated to do so. This is especially true when they reach the age of thirteen and become a bar or bat Mitzvah. This translated to “son or daughter of God.” The word mitzvah alone means commandment, as in the Ten or 613 commandments in the Torah. These are practically the words and will of God and should be carried out. Every Jew is at the very least obligated to do some of the everyday ones like not murdering, honoring your father and mother, etc. Some people think doing a good deed and doing a mitzvah are the same thing, in some cases this may be right, but not all the time and not literally. They are similar, however, and both are nice to do. Anyway, the mitzvot were likely put into the Torah so that one of the ways of life a person can have is simply following all of them.
. One mitzvah is to keep kosher. Animals that are prepared in a kosher fashion, so to speak, likely have a better experience dying than an animal who is just killed to be used for food without any other things to worry about, as far as experiencing death goes. If animals cannot defend themselves, they at least deserve to die with as little pain as possible. Keeping kosher helps to encourage more kosher food prepared, which comes from animals meeting their maker without too much pain.
Also, even just the Ten Commandments by themselves are already a good code of conduct for the average person. The average man or woman utilizes most, if not all, of these commandments in his or her daily life.
And now let’s talk about God. Without God, do you really think we would be here? I believe a good number of people would answer “no” to this question. Whether they believe the story about Adam being made from the earth, God causing the Big Bang, etc., something created the Universe (or as some people believe the Multiverse) and we owe everything to whatever entity is responsible. Thank God!
