Initially it just sounds like a huge task to me, too big to accomplish with 3 or 4 people. I have a friend who dedicated his life to making something similar and he's a mess now. Because when you do eventually realise that your "Life's Purpose" is not going to work out, it will be difficult to admit and move on from it, and hard to take. These things, private teams trying to make something big, almost always fail. Plus, the extreme religious undertones will probably turn a lot of people off. It would be best to dedicate your life to something with a surer outcome.
