The Ending was a Religious Message **spoiler alert**
**spoiler alert*** do not read if you don't want to know what happens in the end.
The whole movie, really, played a huge commentary on religious matters. The ending put a final stamp on the religious commentary and this is what it meant:
The 5 of them in the jeep believed (religion) that this was it, that there was no more point to life. The monsters win, we lose. There is no reason to hope and no reason to live, so they decided to take their own lives by gun. Of course, they only had 4 bullets left for 5 people, so the main character survives only to have live with the torture of realizing they were wrong, there really was life and hope after all this.
You see, many people think the same way. They think that life has no meaning or that there is no God or no heaven, and decide killing oneself is perfectly fine. Of course, later on, they will realize that there is life after death, hope after despair, a light at the end of the tunnel after darkness. Just like in this story, if they had just waited a little longer and not killed themselves, they would have been fine. The soldiers were literally right there within seconds of them before they committed suicide.
So the message is, if you choose NOT to believe, the risk is you lose everything, just like he lost his son and the others in the jeep. If you choose to believe and it's not true, you don't risk and lose anything. You just continue onto the process of death as you naturally would have anyways.
So it's better to have some faith and hope than to not be a believer at all.
Now, I'm not talking about that psycho cult lady. She wasn't representative of the true gospel...she was in some sort of psychotic neurotic paranoia of the old testament times. Of course, anyone that knows the reality, the OT has become nullified in terms of the works and sacrifices we were required to perform, because the NT has provided and no more of that OT crazy *beep* needs to be performed.
Cheers.
