Christianity is vastly different from all other religions in one respect that I know of (there are probably many more).
In Biblical Christianity, a human being has NOTHING to offer God. There is nothing one can do to “earn” salvation from Jesus Christ. In fact, one must admit to one’s total bankruptcy spiritually, morally, and sometimes other ways as well. Then it’s up to Jesus Christ to save the person. When He does so, they become a completely different person in Him.
In all other religions, including ones that claim to be a “kind” of Christianity, the human being has a certain prescribed set of things to accomplish or goals to meet to “earn” whatever that religion is saying it offers. Even Catholics, Jehovah’s Witnesses, Mormons and Christian Science followers have a prescribed set of goals they must attain in order to get whatever that religion claims.
In Biblical Christianity (meaning what the Bible alone says about being a Christian) the decision is entirely up to God to save or not save. And once you are saved, you are forever saved. Even our most wonderful deeds of goodness are as filthy rags before the Creator of the Universe. We depend on Him for all.
