Well, before we can get into the question of which one is true, we need to clarify something. There are not thousands of religions. There are not even hundreds of religions. There are only two: one which tells you that salvation comes as a reward for what you have done, and one which tells you that salvation comes by what somebody else does for you. That’s Christianity. All the rest fit under the other. And if you think you can get your salvation by your own efforts, then Christianity has nothing to say to you. But if you know you need to be saved, then you are a candidate.- Quoted by Ben Patterson in Muscular Faith.
