Don't be upset with the nations of the world because they don't understand us; they're not capable of understanding us.
Many of our own brothers and sisters don't know what it means to be a Jew, so what can we possibly expect from our neighbors? One of life's biggest tragedies is when the King's own son and daughter don't know who their father is.
Our Father in Heaven can do whatever He wants, whenever He wants. Nature is nothing more than a tool in His hands. Whenever He so desires, He overrides nature. We call that miracles, but for Hashem, it's business as usual.
