If all religions lead to some kind of heaven, then does is really matter who and what you believe in?
Believing something does not make it so. During the height of the 1960’s LSD craze, some people believed they could fly. They jumped from windows. Want to guess what happened? The faith one has is only as good as the Object of that faith. You can have faith in a rock, and it will actually help you and produce some results. When it is time to die, however, what power does that rock really have? Many religions have statements of truth which contradict one another. Christianity claims there is only one way to Heaven- faith in the atonement and person of Jesus, and a relationship with Him on His terms. The reason for the nature of this relationship (Lord and servant) is that only if you give Him authority over you voluntarily can He justly save you without violating your will. Either it’s true or it’s not. Some other belief systems can be true at the same time. If two contradict, one must be false. It’s what we call the "Law of non-contradiction", and one of the ‘Laws of logic".
John 14:6
Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me."
