The Chovos Halevavos explains that as you cannot harm me, you cannot help me as well. Explains the Chovos Halevavos, I have to understand that Hashem is directly involved in running the world, directly involved in my life. No human being can harm me and no human being can help me. You can scheme, you can dream, you could have the most carefully laid plans to harm me. If Hashem doesn’t will it to be, you cannot touch me.
As you cannot harm me, you also can’t help me. You could be the wealthiest fellow in the world and you’ll wish to give me tremendous sums of money. If that money wasn’t coming to me, it’ll go in one pocket and out the other. If it was destined to be the end of my time, my brother could be the head of Sloan-Kettering Cancer Department, but there is nothing that he can do to help me. As you cannot harm me, you cannot help me.
A mashal (allegory) to understand this is that when I walk down the street there’s a Lucite bubble that protects me. You can throw rocks, you can try to penetrate it, but you can’t get in. There is no Lucite bubble, but there is Hashem. Hashem walks with me all day, every day. Hashem protects me. You can scheme, you can dream, but you can’t penetrate. As you cannot harm me, you cannot help me. Hashem determines every outcome. Hashem is involved in every activity that happens in this world.
