It must be questioned by a number of people in a myriad of faiths, the nature of their peculiar gods.
Roman Christians live in guilt..the other Christian denominations live in the hope of life eternal, and are overjoyed to pray to a benevolent god.. Muslims believe of proselatizing the entire world and the re-establishment of the Caliphate, and are quite willing to die for it.. The Jews believe their salvation has yet to appear, while praying to a god who throughout history has led from from one disaster to another...Buddhist believe in reincarnation, as do Taoists.. yet another turn around the wheel..
But at some time throughout their lives, they undoubtedly wondered if they were following a dead end track..
It would require an epiphany not unlike that reported by Saul of Tarsus to bring each back to a stste of total confidence.
Especially with the world in it's present state.
