Did anybody see that movie 'Constantine' with Keanu Reeves?
In it, as a young man (or boy, it's been a while since I saw it), he dies, but is revived in an ambulance about 30 seconds later. The thing is, while he is dead, he is sentenced to hell, and the 30 seconds he spends there changes his life. When he is revived, he doesn't just believe that God/Heaven exist, he KNOWS it.
Here is one of the major conflicts: he doesn't BELIEVE in God, but instead KNOWS that God exists, which is different. Belief as I understand it is holding something as true without direct evidence, whereas to know something is to have observed it as true. God wants us to choose him because we love and long for him, not because it has become blatantly obvious after we die that he exists. If we only choose God after we KNOW he is there, that's not faith, it's observation.
