I know i'm going to get a ton of shit for this, but i really am not a doomer. I think this is a legitimate question...
IN THEORY: What if all of this has all been misunderstood, and isn't what we all think? Is there a plan B, C, D etc. if what we are waiting for doesn't happen for one reason or another?
We have to put all our faith in God.
Revelation 2:10 (NIV)
Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you life as your victor’s crown.
