I was taught that it was a matter of simple trust in God. But there wasn't a big Jewish community where I grew up, so my religious education is spotty and often self-taught. If you haven't already, you should catch up with a poem that explains my beliefs in more detail.
Then why aren't you rectifying that situation? Is there any knowledge that is more profitible to you than knowledge of G-d and His ways?
Shalom.
