At first it's highly recommended to be tolerant, understanding and open-minded. Accept and acknowledge all of the leading prophets on the market—you must say you respect and recognize at least Moses, Jesus and Mohammad. Depending on the following you have, consider adding such characters as Buddha, Bahaullah, Ron L. Habbard, Gandalf, Kurt Cobain, etc to your "Authorized Prophets" list.
Leave crusades, autodafes and infidel massacres for later. Whether you like it or not, some day you will have to inject refreshing zeal into your religion, and wild, effervescent carnage still soars as THE unbeatable faith stimulator.
