I'm a man of faith, and I can tell you now what your 'friend' is doing is wrong.
God loves us, but he gives us choice. We must respect that. And that your friend, although the bit I've read, is pretty much forcing you into religion. Your friend is telling you the bad things, which puts a bad eye for Christianity. If I were to tell a friend about God, I would give the best of love for it, not say
"You can either follow God or burn in hell for eternity." Your friend isn't speaking the right of what I think God would want them to speak. A Christian should be accepting and loving, not forcing religion upon those who dissagree. I for one have a lot of fallen friends who believe in all sorts of things, but they're friends, and I love them. And I accept who they are. I just wish God could show them the love.
In other words, Your friend needs to learn how to love someone, and how to tell a nonbeliever how God is. Not Haten', but Lovin'.
