This lecture, delivered by Rabbi Elyahu Kin, is part of the series "The Hand of G-d," and describes what is a miracle, and how to distinguish it from Witchcraft or plain random acts of nature. Rabbi Kin elaborates on how miracles demonstrate G-d's involvement with His Creation, and how they have the potential to awaken in us the faith in G-d, and to strengthen the faith in those in need of hope and encouragement.
