LOL but yes, impact is the source of all trolling.
I actually agree with you on this to an extent, however there is one fundamental flaw in the argument, well actually it's a fundamental flaw in their argument to make us repent for past sins. God is supposedly in the eyes of the Christian Church all forgiving. If God is all forgiving in the eyes of the church then really we don't actually need to repent for all our sins are already forgotten.
If God is truly all powerful and thats a big if and if he rooted for the Stormtroopers then the Stormtroopers would win end of.
Now really if the worlds going to end in our lifetimes is there any point in worrying about it? Really, the world is going to get destroyed. We don't have interstellar spaceships capable of evacuating the place or even of building one in time to save less than a measly 1%. If the Earth was going to be destroyed by natural occurrence say, Armageddon style (the movie, alternatives include Deep Impact basically an asteroid/comet smashing in to the Earth) then we would know about the event taking place several weeks in advance and all normal life would probably grind to a tremendous halt and we could just live life like there will be no tomorrow in x many days time. In which case I would probably spend my last days doing things with my friends and say smurf my job, smurf taxes because Death is more than certain.
If however the world is simply going to get destroyed by an all powerful being who is acting like a douche because we don't believe he exists anymore then he's hardly going to advertise the fact he's destroying the world and if he did advertise it and demand our affections and belief then I would say he doesn't deserve it because it's taking our right to free will away from us and that he can go ahead and smurfing kill me because I will never beg him for my existence or exist in a state where my will is meaningless.
Simple really.
