Dear 100 Hour Board,
Where are you going - heaven or hell?
Kirito does a good job of explaining what hell might be below. I just want to point out that the Telesital Kingdom is a place for "liars, and sorcerers, and adulterers, and whoremongers, and whosoever loves and makes a lie," and that its glory still "surpasses all understanding" (D&C 76).
We've talked a lot about this in my Doctrine and Covenants class. Every Christian sect has wondered about it and Mormonism isn't different in that regard. What does make us different, though, is our view of the purely infinite Atonement of Christ. It applies to everyone in every circumstance, even those who are ignorant of its existence. This means that the age-old question of "Are you saved?" has already been answered because everyone is. Because of that, life instead becomes a question of are you preparing for exaltation, or brought to the high level of God.
The LDS Bible Dictionary teaches that hell can mean two different things. The first is spirit prison, which is temporary. The spirits of those going to the telestial kingdom will be stuck there until after the Millennium, paying the price for the sins until an eventual redemption. The second is outer darkness, a place reserved for the devil and his angels, which is a permanent hell with no possibility for redemption. Since we're here on this Earth, that means we chose God's plan before this life, which makes it extremely unlikely for any of us to change drastically enough to end up there.
The Book of Mormon mentions hell at least 61 times. Each time is referring to one of these two types of hell, distinguishable by context.
As for me, I plan on going to heaven. Heaven can mean any form of redemption, and nearly everyone on the Earth will receive redemption from Christ to some degree. However, not all redemption is equal, and I'm aiming for everything God has to offer—to become like Him. That's the reason I was baptized as a Mormon, and it's a promised blessing of that covenant as long as I don't fall away. So I'm counting on that blessing, not out of presumption or pride, but out of faith and hope in my Savior. He says He can save me and I have to believe that.
