I don't recall the context in which the movie discussed danger, but of course there are many kinds of dangerous situations which do not represent "grave danger," or "extreme danger."
For example we might face a danger of running out of beer at our tailgate, or a danger of a basketball game being cancelled because of snow. These would not represent grave dangers to most reasonable people.
The danger that there may be a God, on the other hand, would be a grave danger to you while a pretty inconsequential one to me.
I am thankful for the opportunity to set you straight on this matter. Please advise if I can be of further assistance. And one other thing: GOB BLESS YOU.
