True Christianity requires sacrifice!
The etymology of the word Islam actually means submission (to the will of God). The biblical deity also requires the complete submission of ones life over to his will. The god of the Jews has the same requirements and apparently so does Krishna. All religions whether they use the word or not require faith without evidence.
As a believer of any religion that has some sort of holy texts as its basis you must rely on faith that the authors of those texts were truly inspired by their god either through some miraculous way or visions and revelations. Like their god, this puts their claims entirely outside of the reach of scientific and historical research making their claims unverifiable. The biggest problem with this was made abundantly clear by Thomas Paine in 'The Age of Reason:'
"that something has been revealed to a certain person, and not revealed to any other person, it is revelation to that person only. When he tells it to a second person, a second to a third, a third to a fourth, and so on, it ceases to be a revelation to all those persons. It is revelation to the first person only, and hearsay to every other, and consequently they are not obliged to believe it."
Based on the logic of Paine what theists of all religions have is not founded on revelation but on hearsay. It seems to always start with someone making extraordinary claims of events that seemingly occurred conveniently when he was alone in some cave, under some holy tree, etc. This pattern persists throughout all so called revealed religions. Even today we have more modern day examples such as Joseph Smiths claims to have been visited by the angel Moroni.
Whatever happened to the stone tablets of Moses?
I am fully aware that he broke the first set that his god had given him but the same god made him go back and make another set. "The LORD said to Moses, "Chisel out two stone tablets like the first ones, and I will write on them the words that were on the first tablets, which you broke." Exodus 34:1 (NIV). Those were lost along with the Tabernacle of Israel along with some other religious artifacts.
With Joseph Smith the angel Moroni came back to take the tablets back to heaven or wherever he is supposed to abide along with the Urim and Thummim stones he allegedly used to help him translate the tablets.
Submission is necessary because there is no evidence nor any possible way of obtaining any. All of the major religions are founded on word of mouth and faith. The odds of them being true are about the same as any one individual winning a major jackpot playing lotto. For instance playing New York lottery and picking 6 winning numbers out of 51 the odds are 1 chance in 18,009,460! Here is a chart on odds on some of the most popular lotto games right here. I think it is a pretty safe bet to assume that the odds of the existence of a god are fair no better.
Finally, when you decide to submit you also have to decide to which god to submit to. What if you submit to the wrong god? Then you are condemned either way for worshiping false gods and idols. With religious beliefs you can't win. Which god should you worship, what evidence is there to prove he/she/it is the right god, how can you rely on subjective experiences since most other religious adherents claim to have the same or similar experiences with their god of choice. Basically you submit without evidence and your subjective experiences will confirm the truth of your religion of choice! Subjective religious experiences don't count as evidence so good luck with that.
