That's a very sophmoric understanding of the current monotheistic religions. If you believed any one of them to be true, then you would have to admit that there was at one time one pair of humans and one Creator God - anything that stems from that (ie Baál worship) would have to be considered stemming from Adam, not just Abraham.
Your careless and disrespectful approach towards the three (or more if you consider the Roman Catholic religion different from Protestant, and Jehovah's Witness and Mormonism) completely ignores purpose, philosophy, and the cultural ramifications of each faith.
The Jews and Christians [should] agree on the concepts of sin and atonenment. Yet the Jews are still looking for their Messiah and reject the true savior. That is an extremely different point since it ignores grace and maintaines fealty to the Law. Hence there are remarkable differences in the culture and outlook of the future between the faiths.
The Muslim faith is a demonic faith. They reject all of God's prophets and replace them all with some psycho pederast. (At least Michael Jackson didn't marry the children he was fooling around with). As a result, they are following the doctrines of Demons. So what if they channel all of their worship energy to some fiction named Allah. They have you and many other intellectually lazy people fooled. Just because they aren't polytheistic then in the child-like rationalizing of the culturally ignorant crowd they must be serving the exact same god as Jews and Christians.
but Muslims can be very good people
And what exactly does that comment have to do with anything up to this point? Atheists can be "very good people". In fact, serial murderers can be considered "very good people". Why? Because if a person does not have an objective standard for "good" then anything can be considered "good" or "bad" based on the whimsy of the commentator.
I know some that are actually better people than some individuals who call themselves Christians.
I think that this is proof positive that thoughtless pigeon-holing of people substitutes for careful consideration. I could call myself "Bill Gates", but the discerning bank teller would not cash a check that I sign under that name and bank account. Ask yourself this question, are you so undiscerning or so eager to be nice that you will believe anything anyone tells you? Do you buy swamp land because someone told you it was beach-front property and you could get it for a song?
Christianity is so much different from every other religion that it is easy for those who are products of current government education to believe the total lies of the anti-God State and feel that Christianity is all about being "nice", and anyone can be a Christian just by being nice.
[Insert Calvinist lecture on Soteriology]
A person can "choose" to adhere to whatever religion or lack of religion they want with the exception of Christianity. True Biblical Christianity is not something people volunteer for, it is what they are drafted into. Just this fact alone should place miles of difference between Jews on one side and Muslims on the other.
[Insert lecture on salvation by grace not works]
For religions that depend on good works in order to merit rewards, it would seem axiomatic that they strive harder to please men then Christians who are saved by grace, and their works are not designed for pleasing men.
Christianity is no guarantee of Heaven, if one only uses Christianity as a get out of Hell pass.
I don't know if you are trying to be blasphemous or really don't know much about what you are critisizing. Christianity is based on the promise of atonement. Hell is for those who are not saved by grace, which requires a Christian faith. If a person wants to worship one third of God (as the Jews), a fictional god (like Muslims) a bevy og gods (like Hindus) or no god (like Atheists) then Hell is certain. To use the pejorative and insulting phrase "get out of Hell pass" shows the same attitude towards Christians as one would have while spray painting a swastika on a Jewish temple.
