Enjoy The Matrix. Build some of your physical and mental prowess with Yoga. But go to the Bible for eternal life.

You are allready blessed with eternal life. No-one on earth has the power to grant or restrict that based upon religious conditions. To believe is sometimes to fail to see that point because a book allready provides an acceptable awnser to cover your conscious. This is perfectly fine when it soothes a man from his worries but needs to be stopped when it turns into a pissingcontest with other religions, or worse.
All religions squelch the mind, some minds tho have not developed a sense to see that as unfit. And in those cases it isn't unfit at all: minds in need of guidance should be given guidance, in whatever form. A church is a good start but using your mind indepently is where it should finish.
Maybe not in this lifetime, then surely in the next.
Okay, we have a difference of religious beliefs.
If Jesus were simply a man, He could do nothing. The facts of the miracles that He did, along with His resurrection and ascension show that He is God as well as man. That is why only He can offer salvation. If we could do it ourselves, we would. But we don't because we can't.

EDIT: The mind of mankind is flawed. It can never come to the correct conclusions on its own.
