Menachem Mendel of Kotzk maintained that "whoever believes in miracles is a fool; and whoever does not believe in miracles is an atheist."
How can the idea of the miraculous be meaningful to us today? We may be guided by the biblical Hebrew term for miracle, nes, which means "sign." A miracle is an event that signifies something of significance, something that makes an important difference in my life or in the life of my community. A miracle is an intimation of an experience of transcending meaning. The sign-miracle does not refer to something beyond or contrary to logic or nature. It refers to events and experiences that make us take notice of the extraordinary in the ordinary, the wonder in the everyday, the marvel in the routine. Signs do not violate reason or nature. They are natural moments in our lives that we recognize as transforming.
