I don't understand why the rabbis created so many laws to ensure that we do not transgress any of the Torah's laws; don't they trust us to do things right?


Here is an analogy:

You insure your house, health, and the things which are important to you. You don't say that I trust myself not to fall down the steps, and that I am confidant that I will not crash my car, because these are things which are too important to leave up to chance.

The Torah is the same way. Every commandment is precious. So precious, that we set up all kinds of precautions to make sure that we do not accidentally transgress.

Not only that, but the very fact that we set up all of these precautions shows ourselves and G‑d how precious these mitzvahs are to us.

After all, we don't insure things that are not worth anything.

Please let me know if this helps.

Yours truly,

Rabbi Menachem Posner
