Everything is a miracle. It is a miracle that one does not dissolve in one's bath like a lump of sugar.
A miracle is an event which creates faith. That is the purpose and nature of miracles. Frauds deceive. An event which creates faith does not deceive: therefore it is not a fraud, but a miracle.
Back of every creation, supporting it like an arch, is faith. Enthusiasm is nothing: it comes and goes. But if one believes, then miracles occur.
