Also, things are gonna be a heck of a lot worse in the future. Wars, famines, etc. My seminary teacher last year did a pretty frightening simulation of what the aftermath of Christ's crucifixion was like in North America to the Nephites (basically darkness, and all that), and it scared the heck out of me, and explained that in the last days, our world would be worse than that. Like I said, we're actually nowhere near the worst that the world can get.
