because g-d never asked us to sacrifice flesh or plants! does not want our bloody offerings!
i'm thinking that maybe we should put our focus on being grateful, and trust in continued blessings. like "i am grateful that you keep me safe, universe, and i trust that you will continue to do so" instead of "please keep me safe! i'll be good." it might be elementary to others, but it was a big lightbulb moment for me.
