Every moment of everyday it’s the exact formula to keep us thriving. We don’t even think about it just expect it. Our Manna today isn’t in the form of food but the very substance that keep us everything going. G-D created the perfect combination for us to take in and exhale out that keeps not only our world working but the life forms around us. It might not be one written in the book but it’s perfect combination of Nitrogen, Oxygen, Carbon Monoxide, Helium etc. is truly a miracle that we often take for granted until we can’t.
